Abstract

The request for enzymes in the global market is expected to rise at a fast pace in recent years. With this regard, there has been a great increase in industrial applications of pectinase owing to their significant biotechnological uses. This study was undertaken with main objectives of meeting the growing industrial demands of pectinase, by improving the yield without increasing the cost of production. In addition, this research highlights the underestimated potential of agroindustrial residues for the production of biotechnologically important products. In this study, the maximum pectinase production was attained by using wheat bran, among the tested agro residues. These studies deals with to produce pectinases enzyme using A. niger in SmF. Agroindustrial residues used as pectin sources were wheat bran, citrus peel, sugarcane bagasse, rice husk, potato peel and orange peel. Best pectinolytic activity based on the diameter of clear hydrolyzed zones on the pectin agar media plates was obtained with A. niger. The strains of A. niger have good prospect for pectinase production. Wheat bran is a good low-cost fermentation substrate for pectinase production by the investigated fungus. The increased level in the production of pectinases was noticed when the agrowastes were supplemented with additional metal ions was more effective in submerged fermentation.

Abstract

Mango is one of the most popular fruit crop of India having high nutritional value. Among the all cultivars Langra is most popular under North Indian conditions. But it has shorter shelf life of 4-5 days. The present investigation was carried out to assess the effect of nutrients on yield, quality as well as postharvest behaviour of Cv. Langra. The treatments included CaCl2 @ 4%,CaCl2 @ 6%, CaCl2 @ 8%, K2SO4 @ 1.0%, K2SO4 @ 1.5%, K2SO4 @ 2.0%, Borax @ 1.0%, Borax @ 1.5%), Borax @ 2.0%, ZnSO4 @ 0.2%, ZnSO4 @ 0.4%, ZnSO4 @ 0.8%. Pre-harvest application was done at 30 days before harvest and fruits were evaluated at intervals of 3, 5, 7 and 10 days after ambient temperature storage. The foliar application of macro and micronutrients had immense potential to increase the quality as well as shelf life of fruits. Results showed that calcium chloride (4.0%) was found best in reducing weight loss along with minimum decay on the 10th day of storage. However, borax (1%) effectively maintained other quality attributes like TSS, sugar, total carotenoids, ascorbic acid till 10 days of storage. Therefore, CaCl2 & Borax could be an effective treatment for enhancing yield and postharvest quality.

Abstract

Top soils (0-15 cm) from seven different soil types were collected in order to analyze the status of different S fractions and their relation with available S and other physico-chemical properties of soil. All the S fractions (sulphate S, total water soluble S, heat soluble S, sulphate soluble after ignition and total organic S) and total S were reported very high in Pokkali soils due to the presence of high organic matter and sea water inundation. Total S content of Pokkali soils were recorded with an average value of 26903.33 mg kg-1. In other soils total S content ranged from 230 to 4400 mg kg-1. Other low land soils were also reported with high S fractions where high amount of organic matter was present. Sandy soils from Onattukara sandy plain and northern coastal plain were recorded with lower S fractions. Among the different fractions, sulphate S contributed least to the total S (1.67 to 29.27 per cent). Sulphur fractions showed significant positive correlation with EC, OC, AEC, clay content and negative correlation with pH and sand content. Sulphur fractions were significantly and positively correlated with available S, which is indication of their contribution to the available pool. Organic carbon content showed significant positive correlation with total N (0.988**) and total S (0.906**). Narrowest C:N:S ratio of 2.2:0.16:1 was recorded in Pokkali soils and the widest ratio of 59:6.42:1 was recorded in soils from north central laterite.

Abstract

Development of alleviation strategies and mitigation of metal toxicity by the use of different amendments may be an important approach for improving the plant growth and yield in heavy metal polluted soils, is of prime important. In this regard, present study was conducted during July 2017 to October 2017 at the pot culture yard of the Department of Soil Science and Agricultural Chemistry, Faculty of Agriculture, Annamalai University to evaluate the effect of organic (FYM, press mud) and inorganic (EDTA, potassium humate, lime, gypsum, natural zeolite) amendments on sunflower performance and nutrient uptake (sulphur and micro nutrients - Fe, Zn, Mn, Cu) under lead and cadmium stress conditions. Results revealed that significantly more Pb and Cd were immobilized by FYM, press mud and gypsum amended pots by having positive influence on physico-chemical properties compared to other amendments. Consequently, enhanced the uptake of iron (Fe), manganese (Mn), and zinc (Zn), copper (Cu) and sulphur (S) and improve DMP and seed and stover yields of sunflower. Whereas lime and potassium humate amended plants registered lower nutrient uptake, DMP and yield indicating that increased metal-nutrient interactions due to lesser immobilization of heavy metals by lime and potassium humate in soil. From the findings, FYM and press mud application alleviated the negative effects of Pb and Cd in soil and enhanced the dry matter production and yield of sunflower as a result of decreased heavy metals interactions with plant nutrients which increased the plant nutrient uptake.

Abstract

Plant Growth Promoting Rhizobacteria (PGPR) represents a broad diversity of bacteria resides on the root surface and root vicinity. They involved in varied biotic activities of the soil ecology to make it active turnover and sustainable for agricultural crop production. The present experiment was conducted to evaluate the effect of Azospirillum lipoferum, Rhizobium radiobacter and Bacillus megaterium on the plant growth parameters, yield and nutrient content in finger millet. The results showed that inoculation with bacteria either individual or combined had an encouraging effect on growth and yield of treated plants as compared to control. Among all the treatments, consortium was best and significantly increased shoot and root length; fresh and dry shoot biomass, fresh and dry root biomass, and number of leaves and tillers. Yield parameters viz. 1000-seed weight (62.29%), grain yield per plant (77.31%), length of finger (45.16%), weight of finger (76.70%), width of finger (29.56%), fingers per panicle (38.28%), and number of grains per spikelet (36.99%) were observed maximum in consortium treatment followed by individual treatments over control. Our results showed that combined treatment also reduced the maturation period of the crop by 33 days. A nutrient profile such as nitrogen, phosphorus, potassium and iron of different plant parts and soil were improved best in consortium treatment. The present study depicted that combined inoculation of PGPR is an efficient and sustainable resource for the better yield and quality of finger millet.

Abstract

Compatibility between organo phosphorous compounds like monocrotophos 36 SL, Dichlorovas 76 EC and Acephate 75 WP and entomopathogenic fungi studies were conducted at IIRR (Indian Institute of Rice Research), Hyderabad. Each insecticide was tested at three concentrations viz. recommended concentration (RC), sub lethal concentration (0.5 RC) and more than recommended concentration (1.5 RC) against three entomopathogenic fungi viz. Beauveria bassiana, Metarhizium anisopliae and Lecanicillium lecanii (Verticillium lecani) by using poison food technique under laboratory conditions. At recommended concentrations monocrotophos 36 SL found harmless to all the three tested fungi (<20% reduction of the growth of the fungus), acephate 75 WP found harmless to B. bassiana and L. lecanii and slightly harmful to M. anisopliae (20-35% reduction of the growth of the fungus), Dichlorvos caused complete inhibition of growth of the B. bassiana and L. lecanii and 72.40 per cent reduction of M. anisopliae indicating its toxicity to all the tested fungi. So, avoiding mixing of dichlorvos with entomopathogenic fungi.

Abstract

Rice is one of the most important cereals in the world feeding 4 billion people across the world. Direct seeding is becoming an important alternative of rice transplanting and spreading rapidly in Haryana due to labour shortage, escalating cost of production and water crisis. Transplanted rice method on the other hand required flooded water, more labour in the fields. Stress free condition in DSR like it can withstand non availability of electricity for upto 7 days resulting in delay of water supply. This was endorsed by 35% conventional and 68% DSR growers. Early maturity (7-10) days in timely sowing of succeeding crop and DSR is a better economic technology was observed by about 1/3rd of respondents (conventional growers), weedicide cost is less was reported by (94% conventional and 90% DSR growers); low production cost of DSR than conventional (63% conventional growers and 73% DSR growers); followed by less pesticide are required in DSR than conventional were reported by (48% conventional growers and 50% DSR growers).

Abstract

Bio-efficacy of different treatment schedules of intercropping, viz. T1 (potato + onion), T2 (potato + garlic), T3 (potato + tomato), T4 (potato + coriander), T5 (potato + radish), T6 (control) and T7 (recommended insecticide) were evaluated against incidence of whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) in single potato variety, Kufri Jyoti during rabi season of two potato-growing years in 2017-2018 and 2018-2019 from November to February. A great deal of variation in the incidence of whitefly was observed on potato crop and with different intercrops. Among the intercropped treatments potato intercropped with onion (T1) and garlic (T2) resulted in minimum incidence of whitefly, while potato intercropped with tomato (T3) recorded the maximum incidence of whitefly. But intercropping method is not as effective as recommended insecticide (T7) in reducing whitefly incidence on potato.

Abstract

Generally farmers are in a hurry to sow next crop (wheat) after cultivation of kharif crop (rice) and dispose off the straw immediately by burning and without recycling of crop residues. This is a great loss to the farmer as well to the land. Farmers resort to burning of the crop residue as removing it involves higher costs for labour to uproot, chop and mix in the soil. In order to encourage farmers to change this practice, rotavator machine was introduced to chop the harvested crop stalks / stubbles into small pieces and incorporated in-situ into the soil with varying efficiencies depending upon the left over residue. The rotavator prepares the field in single operation. It carries out secondary tillage operations such as harrowing and leveling in single operation. It destroys weeds, incorporates left-over stubbles of previous crop, conserves soil moisture and pulverizes soil. It prepares seed bed in both wet and dry conditions. It saves time, labour and cost. Keeping in view the perspectives of rotavator a study was conducted among 80 rotavator adopters in Kaithal district of Haryana to know socio economic impact of its adoption on farming families in 2017-18. Regarding reasons for adoption of overwhelming majority of the farmers (83.75%) reported that rotavators are capable of tilling large areas of land in a short time period and break up the soil and land leveling followed by eradicating of weeds (82.50%). Water management, time and fuel saving were also reported by majority of the respondents. Cumulative socio-economic impact of using rotavator like increased in investment on quality education of the children (83.33%) and social ceremonies (79.16%) by medium land holding farmers were reported while investment on quality education of the children, payment of amount of credit availed from bank increased, extension contacts increased (80% each) were reported by marginal land holding farmers.

Abstract

A pair of ovaries present in Antheraea mylitta (D.) (tasar silk moth) is polytrophic meroistic type. Each ovary consists of four ovarioles and each ovariole divided in to 3 regions- a terminal filament, germarium and vitellarium. The germarium is the distal part of ovariole consisting of germinal oocytes and vitellarium is proximal part of ovariole consisting of developing ovarian follicles in a linear arrangement. The ovarian follicle consists of an oocytes surrounded by follicular cells. The development and maturation of oocytes in the female insects passes through three phases, the previtellogenesis, vitellogenesis and choriogenesis. The ultrastucture of vitellogenic follicles reveals the transport of yolk material through follicular cells in oocyte. The microvilli are developed between follicular cells and oocyte to incorporate yolk protein from haemolymph to oocyte in the form of electron dense micropinocytic vesicles or pinosomes. Later on, microvilli undergo degeneration and formation of vitelline membrane as well as chorion takes place. The oocyte development process is over prior to emergence of adult female moth from pupa. The present study illustrates the different events in the process of vitellogenesis at cellular level during the ovarian development in A. mylitta (D).

Abstract

Maize is a cereal crop consumed worldwide and its improvement involves a detailed understanding of the biological processes underlying various qualitative and quantitative traits including yield. Opaque2 (o2) a transcriptional factor influences the expression of zein fractions in maize kernel protein. During the development of Quality Protein Maize (QPM) having enhanced levels of essential amino acids, the genetic background of the recipient maize line has an impact. Protein-protein interaction (PPI) is one of the dynamic interaction network that help to unravel the molecular basis of such anomalous behavior. Our current research thus thrusts upon the delineation of all the possible interactions of opaque2 protein through In silico approaches to understand their functional impacts; as many in vitro and in vivo methods of PPI detection have limitations. Sequence based prediction approach databases, DIP and BioGRID depicted the interaction with proteins involved in development, calcium signal transduction pathway and response to external stimuli paving emphasis on its multidimensional function other than quality improvement. Cytoscape version 3.6.1 software retrieved records from IMEx and IntAct databases showed DNA (EBI-1578952) from arath as an interactor conferring its TF behavior. STRING software a gene expression database showed Heat Map of o2 protein with co-expressing dzs18 and pdf1 proteins. A cumulative RNA co-expression score of 0.234 was obtained in Zea mays and none in other organisms.

Abstract

Experimental trials were conducted during two consecutive seasons on 2015-16 at Experimental Farm, Annamalai University, Annamalai Nagar, Tamil Nadu, India to assess the response of different sources and levels of sulphur on hybrid sunflower (Helianthus annuus L.). The experiment comprised ten treatments includes RDF, RDF combines with three sources and levels of sulphur viz. elemental sulphur, single super phosphate and gypsum with each applied at three levels such as 15, 30 and 45 kg S ha-1. The trials were laid out in randomized block design and replicated thrice. Among the treatment combinations, elemental sulphur @ 45 kg ha-1 with RDF (T7) found to be promising with increased seed yield increase up to 86.7 and 103.4 per cent over RDF alone during both the period of experimental study. Highest accumulation of nitrogen, sulphur, phosphorus and potassium were noticed during the period of study. Application of RDF + Sulphur @ 45 kg ha-1 through elemental sulphur enhanced the availability of nutrients and eventually increased the nutrient uptake of N, S, P and K and thereby increased the growth and yield of hybrid sunflower under northern Cauvery Deltaic region.

Abstract

The studies were carried out in a private orchard at Kotkhai (Shimla), India for two years during 2014-15 and 2015-16 to find out the optimum doses of calcium nitrate as an alternate of calcium ammonium nitrate for nitrogen application to the apple trees. Fifteen years-old trees of apple cultivar Starking Delicious raised on seedling rootstock and planted at a spacing of 6.0 × 6.0 meters were selected for the study. Different calcium nitrate doses significantly influenced growth, yield, fruit quality and nutrient contents of apple. Highest trunk diameter, annual shoots growth, leaf area, chlorophyll content, fruit size, weight, total sugars, reducing sugars, soil pH, soil N, soil K and Leaf NPK contents were recorded under RDN through CN, followed by RDN through CAN and decreased with decreasing doses of calcium nitrate. However, highest fruit yield, TSS and available soil P contents were observed under RDN through CAN, followed by RDN through CN and decreased with decreasing doses of calcium nitrate. Application of 60 per cent recommended dose of N through calcium nitrate was found as effective as recommended dose of N through calcium nitrate and CAN for maintaining adequate tree growth and nutritional status of the orchard and improving the yield as well as fruit quality of apple. Thus calcium nitrate dose equivalent to 60 per cent recommended dose of nitrogen could be considered optimum for improving the growth, yield, fruit quality and nutrient status of apple orchards.

Abstract

Data was collected during 2014-15 and 2015-16 from 120 small farmers of 12 villages from randomly selected Amritsar and Gurdaspur districts of Punjab, India, to evaluate the performance of various pulse based crop rotations viz. rice-wheat-summer moong/mash (summer pulse based crop rotation (SPBCR1)), Rice-sugarcane-summer moong/mash (summer pulse based crop rotation (SPBCR2), Arhar-Wheat (main pulse based crop rotation (MPBCR3)), Rice-lentil (main pulse based crop rotation (MPBCR4)), Arhar-lentil (pulse-pulse based crop rotation (PPBCR5) compared to the existing non-pulse based crop rotation i.e. rice-wheat cropping system as (non-pulse based crop rotation (NPBCR6)). Rice equivalent yield in SPBCR1 (129.42 q/ha) and SPBCR2 (126.58 q/ha) was found statistically at par but observed significantly higher compared to all other crop rotations. Rice equivalent yield in NPBCR6 (99.28 q/ha) witnessed significantly higher than MSPBCR3 (87.43 q/ha), MSPBCR4 (87.20 q/ha) and PPBCR5 (68.52 q/ha), gross returns (₹ 185063.46/ha), net returns (₹ 118116.83/ha), crop profitability (₹ 334.58/ha/day) and system profitability (₹ 323.61/ha/day) compared to all other cropping systems. Benefit cost ratio was significantly higher in MSPBCR3 (1.99) than all other crop rotations and SPBCR1 (1.76), MSPBCR4 (1.74) and PPBCR5 (1.66) witnessed significantly higher benefit cost ratio than NPBCR6 (1.55). Among various problems faced by small farmers for cultivation of pulse crops, low production and productivity, low market price of the produce, marketing problems, non availability of suitable varieties and high cost of cultivation was ranked-I (65.28%), ranked-II (57.98%), ranked-III (56.31%), ranked-IV (55.83%) and ranked 5th (51.44%) respectively. The other problems such as unpredictable weather conditions, major price fluctuations, lack of harvesting mechanization, large number of pests and diseases and non- availability of labor etc were found important with less than 50 per cent of mean value.

Abstract

Separate and simultaneous effect of gamma rays and NMU on Lathyrus sativus (P- 24) and Cicer arietinum (RSG- 963) has been undertaken in the present study. The current varieties of grass pea and chick pea were subjected to different doses of gamma rays (5kr, 10kr and 15kr) and 0.02% Nitroso Methyl Urea (NMU). The effect of mutagens was observed in the percentage of seed germination, seedling height on the 15th day and survivability and chlorophyll mutants on the 25th day of sowing. From the result it was observed that all the selected traits significantly affected with the increasing and combined doses of gamma rays and 0.02% NMU in both the legumes. But the simultaneous application of physical and chemical mutagens was more effective. Result indicated variations for the selected characteristics in grass pea and chick pea.

Abstract

This study examines the potential of the African night crawler Eudrilus eugeniae in the bioconversion of paper waste and cow dung into vermicompost and effect of some additives. Free choice experiment was conducted to see the preference of worms towards mixture of paper waste and cow dung. Paper waste was mixed with cow dung to make it feasible for earthworms and after introduction of non clitellate earthworms, various parameters were assessed. It was found that a mixture of waste paper and cow dung acts as a good medium for the survival and reproduction of earthworms. Free choice experiment showed the preference of earthworms towards differentially treated media. Trichoderma treated media was the most preferential medium followed by Vermiwash and Jaggery+buttermilk and control. Significant increase was found in all the parameters like percent increase in number, weight, percent population growth and biomass production. Physico-chemical parameters also showed increment in comparison to control. Vermicomposting is thus a very useful and economic stabilization of this waste.

Abstract

Genetic divergence analysis in rainfed green gram [Vigna radiata (L.) Wilczek] was carried out using 16 genotypes for eight component characters including seed yield. A field experiment was laid under a randomized block design with three replications; observation was recorded on ten plants were selected at random from each plot for each genotypes viz. plant height, pod length, number of seeds per pod, test weight, seed yield per plot and seed yield per hectors whereas for days to 50% flowering and days to maturity data were recorded on whole plot basis among the genotypes of green gram. On the basis of D2, the genotypes were grouped into four clusters where cluster IV had single genotype only. Cluster I contains maximum seven genotypes while cluster II contains five genotypes and cluster III contains three genotypes. Among characters subjected to D2 analysis, test weight (37.50%) contributed maximum towards total divergence closely followed by seed yield per plot (32.50%), days to 50% flowering (14.17%) and plant height (13.33%). In the D2 analysis the characters viz. test weight, seed yield per plot, days to 50% flowering and plant height jointly contributed 97.50 per cent towards genetic divergence. The genotypes RMG-1147, RMG-1139, RMG-1132 and RMG-1134 were having high mean values of these traits. Hence these could be utilized as parental material in future breeding programme for green gram improvement.

Abstract

Current study was conducted to record the seasonal incidence and severity of Pink Mealy Bug Maconellicoccus hirsutus (Green) on two popular mulberry varieties viz. V1 and S36 grown in the mulberry gardens of two villages Kulamdi and Raipur of district Hoshangabad, Madhya Pradesh. Studies on incidence (PI) and percent disease index or severity (PDI) of Pink Mealy Bug Maconellicoccus hirsutus (Green) on the selected mulberry varieties were carried out from the months of October to April during the year 2017-18 and 2018-19 by deploying standard methods. The said pest had been found dangerous to the mulberry gardens caused a significant lose to mulberry yield. Its incidence and severity started increasing suddenly after monsoon seasons and reached to peak in the month of October, afterwards showed a decline with the onset of winter thus indirectly causing loss to silk yield by damaging the quality of mulberry leaf needed for autumn and spring rearing. Role of weather factors in PI and PDI was find out by deploying Pearson correlation. Correlation studies showed significant relationship between weather parameters and pest outbreak. Temperature both maximum and minimum and relative humidity (RH%) of same fortnight and previous fortnight weather showed highest positive correlation with incidence and severity of pink mealy bug. Though the precipitation showed negative impact but not significant enough to show the relationship.

Abstract

The present work has significantly contributed to the methods of weed control in tea gardens of Terai region of Darjeeling District of west Bengal. Chemicals need to work under the influences of local environment and the genetic makeup of the assemblages of taxonomically very widely diversified wild plants. However, presently increasing awareness against the use of chemicals in agriculture and horticulture is a healthy trend and may be in near future we shall be able to develop proper local methodology in controlling weeds of our valuable plantations. In this work the efficacy of two herbicides (Paraquat and Glyphosate) is studied in pre monsoon and post monsoon seasons. Glyphosate is found to be most effective in pre monsoon whereas the Paraquat in the post monsoon season.

Abstract

Field experiment was conducted during Rabi 2017-18. The results revealed that weed control measures markedly reduced crop-weed competition. Both pendimethalin at 0.75 kg/ha (Dry) and pendimethalin + imazethapyr at 0.80 kg/ha (dry), were found significantly reducing weed density and nutrient depletion by both broad leaved and grassy weeds. Pre plant incorporation of pendimethalin at 0.75 kg/ha and pendimethalin + imazethapyr at 0.80 kg/ha were more effective in controlling broad leaved as well as grassy weeds. Weed free treatment gave the higher value of root nodules per plant, seed yield, straw and biological yield and nutrient uptake by crop which were found significantly higher over rest of treatments. Among herbicidal treatments, pendimethalin + imazethapyr at 0.80 kg/ha as PPI seed yield, biological yield and nutrient uptake by crop which were found significantly higher over rest of treatments. Higher root nodules per plant found in pendimethalin at 0.75 kg/ha as PE.

Abstract

Disease free layings of popular double hybrid (CSR6 x CSR26) x (CSR2 x CSR27) were utilized for the present study which was carried out at College of Temperate Sericulture, SKUAST-Kashmir Mirgund during summer in the year 2017. The larvae were fed with normal mulberry leaves till fourth moult. Silkworm larvae in the fifth age till spinning were fed on mulberry leaves sprayed with different concentrations of vermiwash 5, 10 and 15 percent alone and in combination with one percent nitrogen. Daily four feeds of mulberry leaves were given to the silkworms. There was significant improvement in growth and yield of mulberry and also in most of the commercial characteristics of silkworm through foliar application of vermiwash and nitrogen. The maximum larval weight (46.53 g) was observed in T7 (15% vermiwash and 1% nitrogen) and the minimum value (40.97 g) was recorded in T0 (control). The larval duration was statistically non-significant. Cocoon weight was highest (1.979 g) in T7 (15% vermiwash and 1% nitrogen) and the lowest cocoon weight (1.536g) was recorded in T0 (control). The shell weight (0.448 g) was maximum in T7 (15% vermiwash and 1% nitrogen) and the minimum shell weight (0.343 g) was recorded in T0 (control). The maximum shell ratio (22.63%) was observed in T7 (15% vermiwash and 1% nitrogen) and the lowest shell ratio (19.40%) was observed in T0 (control). The filament length (1171.70m) was maximum in T7 (15% vermiwash and 1% nitrogen and the minimum filament length (929.50m) was observed in T0 (control). The cocoon yield by number was statistically non-significant. The maximum yield of cocoons (17.88 kg) was recorded in T7 (15% vermiwash and 1% nitrogen) and minimum yield (12.73 kg) was recorded in T0 (control). The thinnest denier (2.890) was recorded in T0 (control) and the thickest denier (3.370) was recorded in T7 (15% vermiwash) however the treatment is non-significant. The highest raw silk percentage (14.322) was recorded in T7 (15% vermiwash and 1% nitrogen) and the lowest raw silk percentage (11.061) was observed in T0 (control). Foliar application of (vermiwash 15% + I% nitrogen) on mulberry leaves resulted in improvement in most of the commercial characteristics of silkworm. Vermiwash can thus be used as a component in integrated nutrient management for improvement in leaf quality and consequently the commercial characteristics of cocoon crop.

Abstract

An experiment was conducted on Jasminum sambac cv. Mysuru Mallige to study the effect of fertigation, micronutrients spray in the soil and leaf nutrient contents in Doddamaragowdanahalli village, Mysuru during 2017-2018. The design used was RCBD with 9 treatments and 3 replications. As there is no standard fertigation schedule for jasmine, so the farmer practicing dosage (200 DAP, 200 g MOP, 50g Urea/plant/year) was considered as a control. The study revealed that, plant applied with 100% RDF (60:120:120 NPK g/plant/year) along with foliar spray of micronutrients (Humic acid at 0.5%, Chelated Zinc and Borax at 0.75g each per plant) recorded highest soil pH (7.18), EC (0.82 dSm-1), available soil N (748.33 kg ha-1), P (294.00 kg ha-1) K (611.75 kg ha-1), Zn (0.77 ppm) and B (0.47 ppm) and highest leaf nutrient status like N (1.85%), P (0.31%) K (1.20%), Zn (39.50 ppm), and B (12.53 ppm) content.

Abstract

Among the various factors responsible for successful cultivation of barley, the optimum uses of nitrogen as well as potassium are of prime significance. Nitrogen is the main constituent of photosynthetic pigments and amino acids which are precursor to protein. On the other hand, potassium is essentially required for plant growth and regulates crop yield and quality. Foliar application of potassium helps in increasing plant height as well as number of spikes and tillers per unit area. Keeping above considerations in mind a field experiment was conducted to study the response of malt barley (Hordeum distichon L.) to nitrogen and foliar application of potassium during the rabi season of 2017-18. The study revealed that plant height, dry matter accumulation, leaf area index, effective tillers, ear length, grains per ear and test weight increased significantly from N0 (control) to N2 (100% recommended N) but N2 (100% recommended N) and N3 (125% recommended N) remained at par with each other. The highest grain yield (48.60 q/ha) and straw yield (66.84 q/ha) was recorded with application of 125% recommended N which was significantly higher than control and 75% recommended N but at par with 100% recommended N. Among foliar application of potassium, there were significant results obtained in growth and yield attributes. The highest grain yield (41.21 q/ha) and straw yield (58.46 q/ha) was obtained in K3 (1% at ear emergence + 1% at 50% flowering) which was significantly higher than K0 (Control) and K1 (1% at ear emergence) but at par with K2 (1% at 50% flowering).

Abstract

Alternaria blight caused by Alternaria brassica (Berk.) Sacc. has been reported to be the most widespread and destructive fungal disease of rapeseed-mustard throughout the world. It has a drastic effect on various yield components which is reflected in reduction of yield up to the tune of fifty percent. Pathogen attacks the mustard crop and develops spots on leaf, pods and seed. Infection of seed results in loss of seed yield and germination. The experiment was conducted with a view to study the effect of different biological control agents on the management of Alternaria blight in rapeseed -mustard under the agro-ecological conditions of red and lateritic belt of West Bengal. The in vivo evaluation of biocontrol agents against Alternaria brassicae showed the supremacy of fungicide, Mancozeb among all the treatments tested and reduced the disease severity (PDI, 9.62). Among the bio-control agents, T. viridae proved to be the best treatment with reduced PDI value (29.44) followed by T. harzianum (31.54), T. virens (33.14) and finally A. niger (43.35) all of them showed significant differences against control (PDI, 58.60). This reduction in PDI was reflected in yield with maximum yield obtained in case of T. viridae (1161.3 kg/ha) followed by T. harzianum (1093.2 kg/ha), T. virens (1041.5 kg/ha) and A. niger (1019.9 kg/ha) against control treatment (990.05 kg/ha). These values were also found to be comparable with Mancozeb (1383.75 kg/ha) proving the scope of using these biocontrol agents in reducing Alternaria blight and enhancing yield of mustard and rapeseed. The effect of these biocontrol agents on various yield components like test weight, 100 siliquae weight and number of siliquae per plant was also studied which again validated T. viridae as the most preferred biological control agent against Alternaria blight, while Aspergillus niger was considered as the least preferred biological control agent. Apart from these studies, the most effective mode of application of biocontrol agent was also studied. It was found that the most effective method of combating Alternaria blight is seed treatment followed by spraying of culture filtrate at regular intervals followed by seed treatment and lastly culture filtrate application. The present study not only validated the role of the studied biological control agents in combating the disease but also provided a scope of using these biocontrol agents for resistance against Alternaria blight without an adverse effect on plant and soil, thereby forming an important part of integrated disease management.

Abstract

The present study was undertaken to evaluate the genotoxic potential of acetamiprid on Allium cepa L. root tip cells. A. cepa L. roots were treated with different concentrations of acetamiprid (0.25, 0.5, 0.75 and 1.0 gL-1) for different time intervals. The results indicate that acetamiprid significantly decrease the mitotic index when compared with their controls (distilled water) at all concentrations and treatment periods. As well as it significantly increases chromosomal abnormality frequency and mitotic inhibition. Different types of physiological and clastogenic kinds of chromosomal aberration were also recorded. This study therefore confirms that acetamiprid acts as a mitotic depressor and mutagenic agent on plant cells when absorbed in a high dosage with prolonged time duration. Therefore, for every chemicals EC50 dose must be determined before field application.

Effect of moisture content on physical properties of three local varieties of field pea of Manipur namely Makhyatmubi, Makuchabi, Ningtekpi and one commercial variety namely Rachna were investigated at three different moisture content levels (15%, 20% and 25% dry basis). The properties such as length, width, thickness, geometric mean diameter, sphericity, 1000 seed mass, bulk density, true density, terminal velocity, angle of repose and static coefficient of friction of the four pea variety seeds were determined using standard methods. The results obtained from the study revealed that as the moisture content increased from 15% to 25% d.b., the seed size dimensions (length, width, thickness, and geometric mean diameter), and thousand seed mass increased. Bulk density and true density of all the seed varieties decreased linearly as the moisture content increased from 15% to 25% d.b. Average geometric mean diameter of 7.40±0.52 mm and 1000 seed mass of 308.92 ± 5.06 g for Makhyatmubi seeds were observed as the largest and heaviest among the four pea variety seeds. The angle of repose, terminal velocity and static coefficient of friction increased with increase in moisture content from 15% to 25%.

Abstract

The present study endeavors to examine direction of farm wage in North Eastern states (NES) of India with the maturity of Mahatma Gandhi National Employment Guarantee Scheme (MGNREGS), using longitudinal data collected from various published sources. The study also assessed the implication of the change in sectoral contribution to gross state domestic product (GSDP) on farm wage in the study area. Beside increase in sectoral contribution to GSDP evidences suggests that farm wage in the study area has moved together with the maturity of MGNREGS. The administrative and locational characteristics might be the reason for higher farm wage in Manipur relative to other selected NES.

Abstract

The climate is a complex, interactive system consisting of the atmosphere, land surface snow and ice, oceans, and other bodies of water and living things. Climate is the weather condition prevailing in a place over many years. It is measured by assessing the patterns of variation in temperature, humidity, atmospheric pressure, wind, precipitation, atmospheric particles and other meteorological variables in a given region over an extended period. Timely and useful information about the possible consequences of climate change, farmers perception of those consequences and available adaptation options etc. is necessary and beneficial of slowing the rate of climate change. To examine how farmers have perceived the consequences of changing climate conditions, a study was conducted in Kohima district of Nagaland State in North-East Region (NER) of India. Kohima district comprised of seven Rural development blocks, out of which one block was selected randomly for the study. The data were collected from 300 respondents identified based on proportional random sampling technique. The perception of respondents about the climate change is studied under the following heads (i) Perception on precipitation (ii) Perception on temperature (iii) Perception on wind speed (iv) Perception on Relative humidity and (v) Perception on impact of climate change. The results revealed that more numbers of farmers have moderate level of perception followed by low and high levels of perception about the climate change.

Abstract

The present study attempted to estimate the yield gap and constraint in Green Gram cultivation in the Nagour district of Rajasthan. The multi-stage random sampling procedure was adopted to choose the sample farmers. In the first stage, Nagour district was selected based on highest green gram area in Rajasthan. In second stage, tehsil having highest area under Green gram ware selected. Later two villages from each tehsil having highest area under Green gram crop were selected in the third stage. For the collection of primary data, a sample of 80 farmers were randomly selected with probability proportion to number of farmers in each size group.Farmers were grouped into three categories such as (1) Small farmers holding land less than 2.0 ha, (2) Medium farmers holding land between 2.0 to 10.0 ha and (3) Large farmers holding land above 10.0 ha. The data pertained to the agricultural year 2015-16. The Total Yield Gap (TYG) is computed as the difference between the potential yields (Yp) and the actual yield (Ya). The results revealed that among the three categories of farmers the yield (gap–I) at overall level, was higher for green gram crop in the selected district, which implies that the technology developed at research station cannot be duplicated on demonstration plots to exploit the full potential of green gram. Maximum yield (gap–II) was observed highest on small farms followed by medium farms and large farms in the study area. The farmers usually do not adopt a technology as package but take up individual practices suitably trimmed to fit into their budget and skills which lead to the variation in the adoption of cultural practices and consequently to the yield gaps. These are constraints found from (over all farmers) that the water shortage was ranked first followed by weeds, and severity of disease and pest attacks were ranked 3rd and soil fertility ranked fourth. Non-availability of input like was ranked fifth.

Abstract

Curcuma longa L. (Zingiberaceae), commonly known as turmeric, is native to Southwest India with its rhizomes being the source of a bright yellow spice with various medicinal applications. It is widely cultivated throughout the tropics. Rhizome is used for its medicinal value and as a dye. In the present study epicuticular wax content of turmeric leaves were analyzed as a part of germplasm screening of turmeric. Thicker wax deposition is correlated with drought resistance in plant species. The epicuticular wax load (EWL) on leaves reduces surface transpiration and thus improves crop water use efficiency. Wax estimation allow us to evaluate the importance of surface waxes in regulating non stomatal water loss. SL 4 and SL7 genotypes had the highest values of EWL, 15.96 and 15.71 µg/cm2 respectively thus expected to have higher tolerance to drought and NTC 189 andPH2 genotypes had the lowest wax of 6.24 and 9.51 µg/cm2 respectively. Genotypes selected based on such criterias will be further used for analyzing biochemical mechanisms underlying drought tolerance. SL 4 and SL7 genotypes had the highest values of 15.96and 15.71 respectively. NTC 189 and PH2 genotypes had the lowest wax of 6.24 and 9.51 µg/cm2 respectively. Cuticular wax potentially decrease transpiration and thus these plants may give higher yields under drought climate condition.

Abstract

A study was conducted to investigate the effect of fruit bagging on post-harvest attributes of grape cv. Muscat Hamburg at farmer's field, during 2018-19 in two seasons. The grape bunches were covered with five different colours viz. blue, white, yellow, red and green non-woven UV stabilized polypropylene bags immediately after fruit set and uncovered bunches were treated as control. The grape bunches were harvested after proper ripening and were stored at ambient condition (26±1°C, 75±5% RH) to assess the shelf life and post-harvest loss in weight. The bunches bagged with white colour non-woven UV stabilized polypropylene bags registered highest berry firmness (9.04 N and 11.16 N), peel thickness (0.12 mm and 0.16 mm), calcium ion concentration in peel (0.47% and 0.53%) and pulp (0.33% and 0.30%) in winter and summer season respectively. Highest shelf life (5.31 days and 9.10 days) and lowest physiological loss in weight (10.17% and 11.16%) were observed in winter and summer season crops respectively in bunches bagged with white colour UV stabilized non woven polypropylene bag (T3).

Abstract

The present study was carried out at College of Temperate Sericulture, SKUAST-Kashmir Mirgund during summer 2017. Foliar spray of Vermiwash with different concentrations 5%, 10% and 15% alone and in combination with 1% nitrogen was prepared and sprayed on the established mulberry plantation to study the impact of the foliar application on mulberry growth and yield attributing characters. There was significant improvement in growth and yield of mulberry through foliar application of vermiwash and nitrogen. The total branch length was maximum (3,774.667cm) in T7 (15% vermiwash + 1% Nitrogen) and minimum (2819 cm) was recorded in T0 (control). The highest Fresh weight of 100 leaves (453.733 g) was observed in T7 (15% vermiwash + 1% Nitrogen) and the lowest (331.517 g) was observed in T0 (control). The maximum yield (2.875 kg) was observed in T7 (15% vermiwash + 1% Nitrogen) and the minimum leaf yield (2.346 kg) was recorded in T0 (control).The maximum moisture content (73.07%) was found in case of T7 (15% vermiwash + 1% Nitrogen) and the lowest (67.34%) was recorded in case of T0 (control). There was an improvement in yield / plant, fresh weight of leaves, total branch length and moisture content of mulberry leaf with treatment T7 (15% Vermiwash + 1% N). Vermiwash thus can be used as a component in integrated nutrient management for improvement in leaf quality and consequently the commercial characteristics of cocoon crop.

Abstract

Tapioca is an important staple food crop in many tropical and subtropical regions in the world. It is grown in India more than a century. Tapioca is drought tolerant crop, can be successfully grown in marginal soils. It is now a major industrial crop in Tamil Nadu. Tapioca is an enterprise that provides support to the rural industrial sector. More than 5 lakhs of rural people are directly employed in tapioca-based industries. This has given employment for the rural mass and augments the economic growth of rural India. Hence this study was taken up to know the market perception of the tapioca growers in Dharmapuri district of Tamil Nadu State with a sample size of one hundred and twenty respondents. The respondents were selected based on proportionate random sampling method. The results of the study revealed that majority of the tapioca growers had low level of market perception followed by more than one-third of the tapioca growers with medium level market perception and less than one-fifth of them had high level of market perception. Hence, it should be definitely noted down by planners and policy makers at State and District level to make arrangement for marketing the products for maximum price. It is also necessary to streamline all the marketing channel. An effective marketing strategy also needs to be framed by the State Department of Agriculture in co-ordination with the regulated markets, commission agents and other marketing organizations functioning at village level. There is a need to establish a separate co-operative society and regulated exclusively for tapioca growers.
