Abstract
Phytophagus mites are the most important group of pests distributed worldwide. Indiscriminate use of acaricides and other chemical pesticides to manage them results in destruction of natural enemies, pesticide resistance and pesticide residues in crops. Hence, exploitation of natural enemies like predatory mites as a tool in pest management programmes has been the main focus of research in recent times. Among the predatory mites, the family Phytoseiidae is known to have potential predators which have proved their efficacy against several mite pests in different crop ecosystems. Classical, augmentative and conservation biocontrol programmes using some of the important phytoseiid mites remained as success stories in developed countries. Meanwhile, the potential of phytoseiids as biocontrol agents of mite pests are yet to be exploited in developing countries like India. Therefore, through the present review, the updated information on the basic as well as applied aspects of predatory mites covering biology, food habits, foraging behavior, feeding potential, mass rearing strategies and their compatibility with other pest management approaches are included.

Abstract
Seeds die inevitably but unexpectedly during storage and current understanding of seed quality and storage conditions do not allow reliable means to predict or prevent this critical problem. Seed deterioration is an irresistible physiological phenomenon. This process is a separate event from seed development and germination. Deterioration caused by field weathering is directly related to seed exposure to adverse conditions. Losses in seed quality occur during field weathering, harvesting and storage. The change of seed deterioration occurs in almost every system, and affects many kinds of enzyme and almost all organelle, as a result, the seed loses its vigor. Seeds are highly susceptible to damage and mechanical injury during post-harvest handling. Several environmental factors contribute to seed deterioration and these conditions make very difficult to maintain viability during storage. Seed quality is depends upon initial seed quality, temperature, moisture content and mycoflora. Chemical degradation of seed components likely occurs through oxidative damage, but the rate of these reactions is dominated by properties of seed that are affected by temperature and moisture. These visco-elastic properties contribute to the structure of seeds as amorphous solids. Rapid deterioration occurs due to these environmental conditions make very difficult to maintain its viability during storage. However, the seed quality and viability during storage depend upon the initial quality of seed and the manner in which it is stored. Seed deterioration is associated with various cellular, metabolic and chemical alterations including lipid peroxidation, membrane disruption, DNA damage, impairment of RNA and protein synthesis and cause several detrimental effects on seed.

Abstract
Thirty sugarcane elite clones/varieties were evaluated for different sugar yield and component traits under two water regimes revealed significant differences among clones tested for different characters in both normal (E1) and water stress (E2) environments. Reduction in brix percent ranged from 3.43 to 23.76 and 3.82 to 18.80 per cent with a mean value of 12.27 and 8.53 percent under stressed (E2) environment at 10 and 12 months, respectively. However, under E2 pol percent reduction in juice varied from 4.72 to 30.43 (%) and 12.59 to 17.38 at 10 and 12 months, respectively. A good range of fibre percent was recorded E1 (11.36 to 14.97%) and (8.50 to 12.24%) under E2 environment. Commercial cane sugar (CCS%) decreased in E2 and drought susceptibility index (DSI) for this trait was lowest for the genotype Co238 followed by ISH159, CoPb12182, CoPb13182 and ISH135 (S <0.75). DSI value for pol (%) cane at harvest ranged from 0.50 to 1.88. In this study, it was inferred that cane yield was more sensitive to water stress than quality traits and clones namely KV2012-2, KV2012-3, KV2012-4, ISH148, ISH07 and ISH135 have ability to withstand water stress conditions with minimum effect on sugar yield traits, and could be considered as drought tolerant.

Abstract
Ethanol is one of the alternative renewable sources of energy with high efficiency and low environmental impact. Various raw materials have been used as carbon sources for ethanol production. Present study was to develop and optimize consolidated bioprocessing to convert the potato processing waste into ethanol using amylolytic strain of S. cerevisiae ETGS1. The fermentation variables significantly affecting the bioethanol production were screened out using Plackett-Burman factorial design. These results identified starch concentration, peptone, yeast extract and incubation time as the key determinants to optimize the process, while MgSO4, temperature, pH and inoculum size had a negative effect (p-value ˂ 0.05).The optimized medium composition for maximum ethanol production was obtained by response surface methodology (RSM) based on a Central Composite Design (CCD). Based on results of RSM, a medium consisting PPW having starch concentration 8.5 g% (i.e. 700 ml effluent mixed with 300 g of gelatinised potato mash), peptone 10 g/l, yeast extract 2 g/l was found optimal and yielded 37.17 g/l of ethanol at 35°C after 84 h of fermentation. The optimized process showed 1.15 fold increase in ethanol yield and 11.5% increase in overall fermentation process efficiency. In conclusion, this study demonstrated that potato processing waste can be used effectively to enhance bioethanol production.

Abstract
The experiment was conducted to determine the effect of feeding attractant glycine on the growth and feed conversion of juvenile Huso huso (Beluga). The experiment was carried out on the juveniles with an average initial weight of 26.04 ± 0.43g at Shahid Marjani center of Sturgeon Hatchery and Cultivation in Golestan province of Iran. After 54 days the weight gain, feed intake, feed conversion ratio (FCR), daily growth index (DCI), daily growth rate (DGR), specific growth rate (SGR) and condition factor were analyzed and were found to be higher in beluga juveniles fed with glycine incorporated diets as compared to the control feed. Among the glycine added diets, juveniles fed glycine of 5, 10, 15 g Kg-1 level showed highest weight gain (134g) by registering 136.6% in growth over control and higher feed intake (7.34) and good FCR (2.20). The weight gain, feed intake, feed conversion ratio (FCR), daily growth index (DCI) varied significantly between the three treatments and the control, however, no significant difference (P>0.05) was found in survival between the different treatments.

Abstract
The present investigation in rice (Oryza sativa L.) was undertaken during Kharif, 2015 at Agriculture and Horticulture Research Station, Kathalagere, India to study the path analysis, character association, variability parameters and identification of transgressive segregants in respect of grain yield and its component traits in F2 population of ‘BPT5204 × IET21075’ cross. The distribution pattern of F2 population indicated large number of genes with dominance based complementary interaction in the inheritance of total tillers per plant, number of panicles per plant, number of grains per panicle, grain yield per plant and L:B ratio in both crosses but duplicate type of interaction was noticed for days to 50 per cent flowering, panicle length, number of spikelets per panicle, spikelets fertility, test weight, grain length and grain breadth in ‘BPT5204 × IET21075’. GCV and PCV values were relatively higher with high heritability coupled with high genetic advance for total tillers per plant, productive tillers per plant and grain yield per plant in both the crosses indicating additive gene action in their genetic control. Grain yield per plant was exhibited significant positive correlation with plant height, total tillers per plant, number of panicles per plant, panicle length, number of spikelets per panicle, number of grains per plant and spikelet fertility. Path analysis in F2 generation indicated the positive direct effect of total tillers per plant, number of panicles per plant, grains per panicle, panicle length and harvest index on grain yield.

Abstract
A field experiment was conducted during rabi season of 2011-12 at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad to evaluate the effect of heat stress on growth, physiology and productivity in different wheat species under normal irrigated conditions. The experiment consisted of 12 genotypes (UAS-320, NIAW-1415, NIAW-34, HI-1571, DWR-1006, UAS-415, UAS-428, UAS-439, DDK-1025, DDK-1029, MACS-2971 and HW-1098) belonging to cultivated species viz. Triticum aestivum, Triticum durum and Triticum dicoccum and were laid out in a factorial randomized block design with three replications. The different temperature regimes were maintained by manipulating the date of sowing. Significant differences were observed in morphological, growth, physiological, biochemical, yield and yield parameters with different temperature regimes. Among the treatments, low temperature regime exhibited superiority over high temperature regime, while giving a better response to most of the yield contributing characters such as more number of branches, more number of nodes, more leaf area, more TDM, higher percentage of dry matter partitioning into economically useful parts, higher AGR, CGR, SLW, LAI, LAD, BMD, ultimately resulting into more number of spikes, more spike length and weight and 1000-grain weight, thus resulting in higher grain yield. The genotypes UAS-439, UAS-415 and UAS-428 performed better both in low and high temperature regimes, thus indicating their use in breeding the wheat genotypes for tolerance to heat stress.

Abstract
As part of the study conducted in the Department of Agricultural Microbiology, College of Agriculture, Vellayani, Thiruvananthapuram, Kerala, Pink Pigmented Facultative Methylotrophs (PPFMs) were isolated from the phyllosphere of paddy collected from different agro climatic conditions of Kerala by leaf imprint method using Ammonium Mineral Salt (AMS) agar media supplemented with 0.5% methanol and cycloheximide. In all, 46 isolates were obtained. The isolates were obtained from different districts of Kerala such as Thiruvananthapuram, Alappuzha and Palakkad including Attappadi hill tract. The isolates were subjected to morphological, biochemical, and molecular characterization studies. In the present investigation the antagonistic efficiency of all the 46 isolates were assessed against the most important fungal and bacterial pathogens inciting various diseases in different crops grown in Kerala by dual culture technique. The fungal and bacterial pathogens selected for the study were Rhizoctonia solani, Pyricularia oryzae, Alternaria alternata, Phytophthora capsici, Colletotrichum gleosporoides, Fusarium oxysporum and Xanthomonas oryzae pv. oryzae. Out of forty six isolates tested, the isolates PPFM3, PPFM7, PPFM10, PPFM36, PPFM44, and PPFM46 exhibited inhibition against the fungal pathogen Rhizoctonia solani. Four isolates (PPFM9, PPFM11, PPFM14, PPFM24) showed antagonistic activity against Pyricularia oryzae. PPFM24 inhibited the mycelial growth of the fungal pathogen Alternaria alternata. Among all the isolates tested, four Methylobacterium isolates (PPFM1, PPFM5, PPFM10, PPFM28) inhibited Xanthomonas oryzae pv. oryzae. PPFM24 and PPFM37 exhibited antagonism against Colletotrichum gleosporoides. The isolates PPFM19, PPFM24, PPFM26, and PPFM33, inhibited the pathogen Fusarium oxysporum under in vitro conditions and PPFM3, PPFM4, PPFM9, and PPFM22 exhibited antagonistic activity against Phytophthora capsici.

Abstract
The present investigation was carried out in College of Agriculture, Bengaluru and Mandya in Karnataka. In total 80 students and 30 teachers constituted sample size of the study. Ex-post facto research design was employed. Majority of both teachers and students perceived that RAWEP provided; more opportunity to students for practical exposure, organize demonstrations in the framers field, village stay coincides with cropping season as the important merits. Less stipend, inadequate funds to conduct RAWEP activities were as the major constraints. Increase stipend amount, more financial assistance to RAWEP and timely disbursement of stipend amount were the important suggestions to improve RAWEP.

Abstract
The experiment was carried out at Mountain Research Centre for Field Crops, Khudwani and was laid out in randomized block design with eleven treatments replicated thrice during kharif season (2014). The soil of experimental site at harvest was silty clay loam in texture. Incorporation of organic and inorganic fertilizers (T6) enhanced the fractions of zinc in soil and their availability in plants and obviously, their uptake in plant and grain and straw at harvest in comparison to rest of the treatments. Various organic sources significantly increased the contents and the uptake of respective micronutrients in plant at various growth stages over the control (T1), the maximum improvement in the contents and uptake of micronutrients were recorded in organic and inorganic treatments (T6). Application of organic and inorganic sources of nutrient in combination [50% NPK + 50% N (FYM) T6] remarkably increased nutrient content, uptake and yield of rice than control. Dry matter accumulation at tillering, panicle initiation and at harvest was 39.54, 67.10 and 160.22 q ha-1, respectively than control. Zn uptake at tillering, panicle initiation and at harvest was 0.22 and 0.36 kg ha-1, straw (0.21 kg ha-1) and grain (0.15 kg ha-1) in comparison to control. Higher straw and grain yield 10.81 and 6.87 t ha-1 was also in treatment T6. Water soluble, exchangeable, carbonate bound and organic bound and total Zn showed positive significant correlation with Zn content and uptake at different growth stages and yield respectively.

Abstract
Intercropping leads to higher yields and increase the economic returns and greater crop equivalent yield as compared to sole cropping. Intercropping system offers increased cropping intensity as two or more crops occupy the land simultaneously. In intercropping system foxtail millet is most important short duration cereal crop. Yield of foxtail millet is decreasing due to many reasons and one among them is use of local varieties and nutrient supply at the field level. To enhance the yield of foxtail millet, Krishi Vigyan Kendra, Kalaburagi has conducted frontline demonstration in farmer’s field of Kalaburagi district during kharif 2017-18, pigeonpea based millet intercropping system with use of improved Foxtail millet variety (SIA-2644). On an average, yield obtained was 19.2 q/ha under demo plots that is (T1: SIA-2644) as compared (14.5 q/ha) to check (T2: local verity). On an average the Demo plots recorded higher yield parameter viz. number of tillers per plant was (7.6), panicle length and 1000 seed weight was (17.2 cm and 2.55 g) respectively, and higher net returns was in improved variety (₹ 12804.1/ha) compared to check that is local verity (₹ 9151.6/ha, respectively).

Abstract
Rajasthan is one of the major fenugreek producing states, which is used in cooking as seed spices. It is indicated as medicine for digestive problems such as loss of appetite, upset stomach, constipation, inflammation of the stomach (gastritis). Costs with reference to cost of cultivation in agriculture play a significant role in making the farm sector economically viable and feasible. The current reading was intended to conclude the comparative study of cost of cultivation of fenugreek in Sikar and Jaipur. The fenugreek growing farmers of the selected villages within the catchment area were divided into marginal, small, semi-medium, medium and large and the primary data were collected and processed statistically. The per hectare average total cost (cost C2) of cultivation of fenugreek on Jaipur and Sikar farms were ₹ 24137.66 and 23399.93 per hectare, respectively. The average overhead costs were ₹ 7197.96 (29.82%) on Jaipur farms and ₹ 6547.91 (27.98) on Sikar Farms. The net income ranged from ₹ 18108.06 on marginal farms to ₹ 27440.74 on large farms under Jaipur farms and from ₹ 18257.92 to ₹ 28096.08 on the same categories of Sikar farms. The per rupee return from cultivation of fenugreek crop ranged from ₹ 1.79 on marginal sized farms to ₹ 2.11 on large sized farm with an average of ₹ 1.91 on Jaipur farms and there range were 1.86 (marginal) to 2.12 (large) with an average of ₹ 1.94 on Sikar farms. The overall cost of production per quintal of fenugreek crop was ₹ 1154.25 on Jaipur farms and ₹ 1111.78 on Sikar farms.

Abstract
Drought is a major limiting factor which directly affects the yield in rice production. qDTY12.1 is a locus which has a tremendous effect on grain yield under drought in rice. MAS is a time saving DNA marker based technology which had been used to transfer qDTY12.1 from drought tolerant parent IR90019-17-159-B to Swarna sub 1, a mega variety but susceptible to drought. The population was evaluated under TSD and rainfed condition. 11 linked SSR markers were used for foreground selection where 5 found to be polymorphic (RM511, RM1261, RM7195, RM28099 and RM28130). Significant amount of variability was observed for all the yield and yield attributing trails under study. However, maximum variability was observed for grain yield. Correlation analysis indicated that grain yield had significant association with biological yield, harvest index followed by effective tillers, panicle length and plant height. Overall, 30 lines were observed to exhibited qDTY12.1 for all the five polymorphic markers but out of 30 only 15 lines (line N0o. 731, 736, 793, 817, 835, 836, 890, 910, 918, 939, 969, 1005, 1010, 1016, and 1061) were possessing Swarna background.

Abstract
The traditional method of cracking walnut in Kashmir is hammering the walnut by any tool including stone which is not only laborious, slow and tedious but results in wastage because of damage caused to kernels by excessive force. A low cost prototype machine was developed to crack the walnuts wherein walnuts are passed between two wooden rollers. Graded walnuts are passed between two wooden cylindrical rollers which exert uniform force to walnuts and crack their shells which are then removed manually. The uniform force ensures less damage to walnut kernels thereby increasing the productivity of end result. This portable machine can be used by small scale entrepreneurs for extracting kernels for marketing.

Abstract
Financial decision-making for investing in portfolio shares are gaining significance in recent days. This study analyses the validity of Fama French Three Factor model and Capital asset pricing model in portfolio investment in Indian stock market. To maximize share price, it is important to assess two key determinants viz. risk and return. The objective of the study is to compare the validity of the capital asset pricing model and Fama French three factor model in portfolio assets of Indian stock market. The index selected for the study is S&P BSE 200 and within this 120 companies were selected as the sample for conducting the study. To understand the basic type of risk, the stocks are selected from S&P BSE 200 index. The firm specific risk is diversified by grouping the stocks of companies into portfolios. This leads to estimate more accurate returns. A size (market capitalization) and value (P/E ratio) sorted portfolio is constructed for further analysis. Six portfolios were constructed namely, S/L, S/M, S/H, B/L, B/M and B/H. The result shows that B/L and B/M portfolio are giving higher return when compared with other portfolio in the model. The study confirms the reliability of size and value factor for the Indian equity market. Hence the findings are supportive of the Fama French model applied to Indian equities.

Abstract
Grading is the assessment of various parameters of food to obtain its overall quality. The health awareness has focused food industry to give more attention for quality and homogeneity of the product. Grading is of utmost priority for consumer with assured quality to fetch better price for the seller. The market demand gives great emphasis on quality assessment which gives primary importance for grading. Grading of agricultural products is accomplished on the basis of appearance, texture, shape, and size. Manual grading is based on traditional visual quality, inspection performed by human a operator, which is tedious, time consuming, slow, non consistent and uneconomical. An economic grading requires good speed and accurate grading which can be achieved with machinevision assisted grading. In recent ten years, operations in grading systems for fruits and vegetables become highly automated with mechatronics. The machine vision technique is expensive and a trade off is to be looked into for high adoption of technology by common masses. This paper presents a low cost expanding pitch type grader for Walnuts with size based grading. As walnuts move over expanding moving belts they fall under gravity process in accordance with their sizes and are separated in different grades.

Abstract
Sixty three selection indices were constructed on six characters using thirty five genotypes of mungbean by discriminant function analysis. For constructing the selection indices the characters viz. seed yield per plant, harvest index, number of clusters per plant, number of pods per plant, days to maturity and plant height were considered. Discriminant function analysis indicated that selection efficiency of function was improved by increasing the number of characters in the index. For indirect selection, the index involving the combination of five characters viz. seed yield per plant, number of clusters per plant, number of pods per plant, days to maturity and plant height which exhibited maximum relative efficiency and genetic advance of 854.70% and 15.65g, respectively followed by an index based on four characters viz. seed yield per plant, number of pods per plant, days to maturity and plant height which exhibited maximum relative efficiency and genetic advance of 787.09% and 14.42g, respectively could be considered for selection schemes to improve seed yield in mungbean.

Abstract
The present study was conducted at SHUATS, Allahabad during 2013-14 and 2014-15 to study the effect of bio-fertilizers, vermicompost and Trichoderma on fruit quality and NPK residual in field of strawberry (Fragaria x annanasa Duch.) cv. Sweet Charlie. The experiment was laid out in randomized block design with twelve treatments and three replications. The maximum total soluble solids (6.69°Brix) was recorded in T11 (5 kg ha-1 Trichoderma + 2.5 t ha-1 Vermicompost + 7 kg ha-1 Azotobactor + 6 kg ha-1 PSB + 10 kg ha-1 VAM) followed by (6.28°Brix) with T10 (5 kg ha-1 Trichoderma + 2.5 t ha-1 Vermicompost + 6 kg ha-1 PSB + 10 kg ha-1 VAM). The maximum acidity (0.72%) was also observed with T11 followed by T7 and T10 while the least (0.58) was observed with T0 (RDF through chemical fertilizers). The ascorbic acid and total sugars were also found maximum in T11 (55.96mg and 8.12% respectively). In 2013-14 the maximum residual NPK among the treatments was noticed 267.41 kg ha-1 with T11 among the treatments.

Abstract
The study was conducted in selected paddy markets viz. Nizamabad and Suryapet (Andhra Pradesh), Sindhanur (Karnataka) and Toofanganj (West Bengal). The data pertained to the period from January 2000 to December 2015 for Nizamabad, Suryapet and Sindhanur markets and from January 2005 to December 2015 for Toofanganj market. There was an increasing trend in the prices of paddy in all the selected markets and were highly significant at 5 per cent level of significance. The monthly increase in prices of paddy was found to be highest in Toofanganj market, where as it was the lowest in Nizamabad market. In respect maize in monthly increase in prices was highest Udumalpet market, where as it was lowest in Nizamabad market. The results of seasonal indices indicated that the highest seasonal indices of prices were observed in the months of July and September in Nizamabad market followed by Suryapet in the months of February and September, and October and February in Sindhanur market and September and October in Toofanganj market for paddy. The lowest seasonal indices of prices were observed in the month of in Nizamabad and Suryapet markets followed by June in Sindhanur and Toofanganj markets respectively. No price cycles were discernible in the selected markets of paddy as well as maize. The irregular fluctuations in prices did not exhibit any definite periodicity in any of the selected markets.

Abstract
The biologically active compounds present in smoke are now emerging as potential growth regulators. In the present study maize seeds were imbibed with - water, diluted plant derived smoke water and diluted filter paper derived smoke water for 14 hours. It was observed that the germination percentage and seedling growth of different maize genotypes were enhanced in seeds treated with smoke water (derived from filter paper and plant residues) as compared to seeds treated with water. This enhancement is partially due to changes in water uptake pattern and seed reserve mobilization.

Abstract
An attempt has been made to examine the carry over stock, production, and consumption pattern, marketed and marketable surplus of pearl millet on different farm sizes and to study the factor affecting the marketed and marketable surplus. Primary as well as secondary data were used for the study. Primary data were collected during the year 2011-12 on pre-structured schedules. Pre-testing of the schedules was done by collection of data from few farmers through personal interview method. Secondary data in respect of area, production, yield, were obtained from Deputy Director of Agriculture, internet and various issues of statistical abstract of Haryana. The analysis of marketable and marketed surplus of pearl millet revealed that overall marketable and marketed surplus was 5343.25 kg/acre and 4630.25 kg/acre in Mohindergarh and Bhiwani districts, respectively. It was observed that there was no difference between marketed surplus and marketable surplus in both the districts. It was because no distress sale was recorded and no stock was retained by the farmers for the next year. With the increase in the size of holding among the different component of the total consumption, livestock consumption forms the major portion of total consumption followed by family consumption in both the district. Production, area under crop showed positive relationship with marketable & marketed surplus whereas livestock consumption, family consumption, family size showed the negative relationship with marketable and marketed surplus.

Abstract
Greater yam (Dioscorea alata L.) is a climbing monocotyledonous tuber crop belongs to the family of Dioscoreaceae and it is reported to be an old crop species native to South East Asia (Burkill 1951). Several environmental factors affect the growth of yam, in particular, the development of the flowers, tubers and bulbils. Tuber growth in yam is slow immediately after initiation and then it becomes very rapid at full canopy formation and finally slows down during maturation with a loss in dry matter (Onwueme 1978).

Abstract
Cotton, often referred to as the White Gold, is an important cash crop of India and it plays a key role in the Indian economy. It provides livelihood to more than 60 million people by way of support in agriculture, processing and use of cotton in textile (Barwale et al. 2004). Cotton occupies a predominent place among cash crops touching the country’s economy at several points by generating direct and indirect employment in the agricultural and industrial sectors. It is being cultivated over an area of about 9.5 million hectares, which represents approximately a quarter of the global cotton area of 35 million hectares. Despite low productivity, India has become the largest producer as well as consumer of cotton, next only to China.

Abstract
Agri- based industry primarily concerned with agriculture and business activities related to allied sector. Agro based industries involved in the production, processing, marketing and transportation of agricultural produce. Agribusiness activities covers a variety of industrial manufacturing and processing activities based on agricultural raw materials as also activities and services that go as inputs to agriculture. Agriculture can be transformed into more attractive from passive stage and can create huge employment opportunities through forward and backward linkage by development of agri-based industries and agribusiness. Under this paper an attempt was made to explore the various opportunities offered by agro-based industries. Agri-based industries can play a very significant role in generation of various employment opportunities for rural youth in villages itself and has lot of potential to contribute and enhance rural income which consequently helps in improving standard of living of rural people and also helps in checking the migration of rural youth from rural areas to urban centers. There is need to review the above mentioned situation of agribusiness sector or industries based on agriculture in totality and present it from comprehensive perspective which include detailed analysis from production to marketing aspects of agroindustry and alleviate the constraints faced by agro-industries.
