Abstract
Assessment of soil erosion risk, especially in hilly areas, is a challenging task mainly due tovariability in topography and non-availability or insufficiency of relevant data. The Revised Universal Soil Loss Equation (RUSLE) model is applied worldwide for prediction of soil loss. Although it is an empirical model, it not only predicts erosion rates of ungauged watersheds but also presents the spatial heterogeneity of soil erosion that is too feasible with reasonable costs and better accuracy in larger areas. Remote sensing (RS) technology plays an important role in mapping of soil erosion risk in agriculture, forest and degraded land. Its application in the soil erosion risk mapping introduces new opportunities for conservation planning and management. With the incorporation of Geographical Information System (GIS), it is possible to analyze satellite data, which gives required information like land use and cover, slope, distribution of rainfall, flow direction etc. of study watershed. The capabilities of these technologies even increase when they are integrated with empirical erosion prediction models like RUSLE. RS and GIS integrated erosion prediction models do not only estimate soil loss but also provide the spatial distributions of the erosion. Generating accurate erosion risk maps in GIS environment is very important to locate the areas with high erosion risks for prioritization and to develop adequate conservation techniques. Micro-watershed prioritization within a large watershed is considered as one of the most important aspects of planning and development for natural resources for soil and water conservation measures. This review article highlights the application of RUSLE, RS and GIS technology in the study of soil erosion and gives an insight of their valuable application in soil erosion risk mapping.

Abstract
The practice of rearing silkworms for raising cocoons to be reeled for silk yarn production and finally weaving of fabrics is in vogue in almost every state of India. The state of Jammu and Kashmir is also one of the traditional silk producing states where sericulture is well suited to elevate the agrarian economy and people of the state continue to augment their income through silkworm rearing. Although during the times gone by the rearing of silkworm was the only occupation available with the stake holders of the rural area, yet with the passage of time there has been a shift from sericulture to other ventures available to the farmers. The reasons of such shift could be on one hand attributed to availability of more lucrative avocations and on the other hand reduced productivity of cocoons which in turn could be attributed to non adoption of various technologies available in the field of sericulture. Such technologies if taken or adopted by the farmers would definitely result in fetching more revenue to them and thus could pave way for setting sericulture industry back on the path of sustenance. These technologies are available in various components of sericulture viz. mulberry cultivation where different propagation techniques, soil fertility management practices besides various protection technologies can be adopted by the farmers. Similarly chawkie rearing and adult age rearing technologies besides silkworm disease protection measures are also available for adoption by them. The present paper besides reviewing the impact of various technologies available in sericulture also highlights some of the constraints faced by the farmers and brings out reasons for non adoption of technologies by them.

Abstract
Heterosis is one of the most important phenomenon for breaking the yield barrier level of crops. Hence, an experiment was undertaken to identify the best heterotic combinations for exploitation of heterosis or hybrid vigour. In this context, five newly converted cytoplasmic male sterile lines were crossed with 6 fertility restorer lines in line × tester mating design during kharif 2014-15. Thus, the resultant 30 hybrids along with their parents and standard check variety (GT 101) were evaluated in a randomized block design with three replications during kharif 2014-15. The results indicated that the manifestation of heterobeltiosis for seed yield per plant was significantly superior of twenty nine hybrids ranging from -2.33-171.67% and fifteen hybrids over standard variety ranging from -21.93 -82.28%. Most of the crosses which exhibited superiority over better parent or standard variety for seed yield also showed significant heterosis for number of branches per plant, number of pods per plant, pod length, biological yield per plant, harvest index and leaf area. The best cross combinations in order of merit seed yield and other yield components CMS GT 603 A × GTR 52 (82.28%), CMS GT 603 A × GTR 23 (76.69%), CMS GT 288 A × GTR 95 (68.78%) and CMS GT 603 A × GTR 95 (53.76%), CMS GT 601 A × GTR 95 (49.41%), CMS GT 33 A × GTR 18 (47.69%), CMS GT 603 A × GTR 8 (46.81%), CMS GT 601 A × GTR 52 (37.30%),CMS GT 302 A × GTR 8 (33.39%) and CMS GT 301 A × GTR 95 (28.61%) were found to be more than 20% standard heterosis for seed yield recommended for commercial utilization.

Abstract
A study was carried out in river Sutlej around Ludhiana to assess the effect of pollution on the reproductive behaviour of some selected cyprinid fishes. Two different sites were selected for sampling of water and fish. The first site was before the confluence of Buddha Nallah near Rail/road Bridge at Ludhiana which is 86 km downstream from Ropar Head works over river Sutlej and second site was 22 km downstream from Site-1 after confluence of Buddha Nallah near village Walipur Kalan. The study was carried out for a period of six months from June to December, 2015. All the major physicochemical parameters of water i.e. temperature, pH, alkalinity, total hardness, total dissolved solids, ammonia, nitrite, nitrate and organic pollution indicators i.e. dissolved oxygen, biological oxygen demand and chemical oxygen demand were studied. Relatively higher values of all these parameters were recorded at S-2 as compared to S-1 however lower values of pH and dissolved oxygen were found at S-2. Besides, this all the biometric parameters of the cyprinid fishes were studied. Although all the fishes bred during the monsoon period but lower values of GSI were found at Site II as compared to Site I. The values of condition factor (K) were found to be low at Site-II indicating an effect of pollution on the well-being of fish.

Abstract
A field experiment was conducted during the kharif season of 2012 and 2013 at Bihar Agricultural University, Sabour, (Bihar) to evaluate the effect of different nitrogen levels and cultivars on yield of rice. The experiment was conducted in split plot design with 3 replications with treatments comprising three nitrogen levels viz. 50% RDN (Recommended dose of nitrogen), 100% RDN and 150% RDN in main plots and five different rice cultivars viz. RAU 724, RAU 759, Sita, Rajendra Sweta and Rajendra Mahsuri in sub-plots. The results revealed that maximum effective panicles/m2, No of grains per panicle, Leaf area index, chlorophyll content, 1000- grains weight, panicle length (cm) and grain yield (q/ha) were the highest value at 150% RDN. The highest grain yield was obtained with 150% RDN (49.0 q/ha) which was at par with 100% of RDN (48.41 q/ha) but significantly superior over 50% RDN (42.04 q/ha). Amongst the cultivars, Rajendra Mahsuri was found to be best and gave significantly more grain yield (72.52 q/ha) than other cultivars. The cultivars RAU 724 (52.22 q/ha), RAU759 (53.33 q/ha), and Rajendra Sweta (51.63 q/ha) were significantly at par with each other. Uptake of NPK was maximum with Rajendra Mahsuri. Maximum net return (₹ 41900 and ₹ 41774/ha, respectively) recorded with 150% RDN and 100% RDN. These treatments also recorded higher B:C ratio (1.56 and 1.60, respectively). Amongst cultivars, maximum net return and B:C ratio (₹ 75528 /ha and 2.90 respectively) was recorded with cultivar Rajendra Mahsuri.

Abstract
Patakapoora, a landrace of Rasthali (Amrithpani) group of bananas are mostly grown in coastal tracts of Odisha, admired by one and all because of its pleasant aroma. However, availability of this variety of banana is limited and has a very poor shelf-life for which the fruits do not reach the distant destinations. Here, an attempt has been made to prepare pulp from the ripe fruits and preserve with KMS to give a better shelf life. The effect of KMS treatment with three different concentrations (0.1%, 0.5%, and 1.0%) on quality attributes of banana pulp was studied. The result of the experiment showed slight increase in TTA and microbial load with a slight decrease in TSS, ascorbic acid, pH, texture and sugars over the 0-30 day’s period of storage in 9±1°C. Though the sensory evaluation rated maximum for the sample with 0.1% KMS. Addition of KMS as preservative and lower temperature storage at 9±1°C decreases the possibilities of higher microbial contamination. Thus, the present study indicated that the processed banana pulp remained in safe consumption level up to 30 days of storage.

Abstract
Small cardamom (Elettaria cardamomum) is a major spice crop cultivated in India and mostly confined to Kerala, Karnataka and Tamil Nadu. With varying degree of climate, disease and insect-pest infestation in last three decades, numerous challenges have been imposed on farmers for sustainable cultivation of small cardamom. Since 1990s environmental conservation has become a key issue in farming community. In this study, I have interacted with farming community and investigated the depth of interest of farmers toward IPM and attitude to adapt this practice. If timely technical/financial support is provided and farmers are made clear about the technology and its ease, it is eventually accepted by them.

Abstract
The present investigation was carried out at Research Farm, S. K. N. College of Agriculture, Jobner, Rajasthan. 60 genotypes of fenugreek were evaluated under normal and limited moisture condition in randomized block design with 3 replications for seed yield and its component characters. Analysis of variance indicated significant genetic variability among the genotypes for all the characters in individuals as well as the pooled basis under both the environments. The association analysis revealed that seed yield per plant was significantly and positively correlated with branches per plant, pods per plant and seeds per pod in both the environment. Path coefficient analysis indicated that direct selection for pods per plant in both the environments, was the important character for selection of high yielding genotype as this exerted high positive direct effect as well as showed high and positive correlation with seed yield. Based on the present investigation it is suggested that in breeding programme major emphasis should be given to pods per plant in both the environmental conditions as it had positive correlation with seed yield per plant with high direct effect. On the other hand concerted efforts on evaluation of a larger number of genotypes are likely to identify genotypes worth exploitation in breeding programme to develop limited moisture stress tolerant varieties in fenugreek.

Abstract
High levels of fluoride present in drinking water causes health problems like dental fluorosis, skeletal fluorosis, risk to brain, thyroid gland etc. Among all water purification methods, Reverse Osmosis (RO) became a best process to remove fluorine. All RO systems runs on electrical power. Power supply in rural areas is a serious concern. Some of the remote villages are still not connected with power grid; hence there is no scope for using commercially available RO systems for water purification. A suitable Solar Photo Voltaic System was designed to run RO system. The designed Solar Photo Voltaic Reverse Osmosis (SPVRO) System comprises of Solar Panel, Storage batteries, Charge Controller, Water Booster Pump, Water purification membrane set. Newly developed SPVRO system can remove fluorine from 1.9 mg/lit to 0.18 mg/lit. The other chemicals such as Nitrate, Iron, Sulfate and Chloride were also reduced to safe limits with the purification process. The SPVRO system has capacity of 9.6-12.8 lit/h, an average capacity of 11.55 lit/h. The overall recovery % of pure water was 37.32 was observed. Less recovery % was due to presence of more chemicals and inorganic substances present in raw water.

Abstract
Mechanical harvesting and threshing of numerous crops in general and Tur in particular is getting popular among large as well as medium scale farmers of northern Karnataka in view of farmers facing acute shortage of labour and time during harvesting. Some of the large farmers made an effort to get machines from other states like Punjab and Haryana for harvesting but, their timely availability is not ensured. The situation calls for investment on these machines by local entrepreneurs. This study was conducted with an objective to analyze the financial feasibility of investment on combined harvesters in the northern part of Karnataka and to document major constraints faced by the owners of the combined harvesters. Financial feasibility analysis was used to analyze the data elicited by ten owners of combined harvesters in north Karnataka and Garrett ranking technique was used to document major problems faced by the owners. Life of the machine was considered as 15 years. Results of the study revealed that investment on combined harvesters in the study area is financially feasible with NPV, BCR, IRR and PBP of ₹ 4016980.42, 1.43, 24.17 per cent and 2.65 years. The major constraints faced by the owners of combined harvesters included fluctuations in area under the crop and quantity of output, high cost of maintenance of machines and workers and transportation problem due to bad roads. For easy availability of machines during requirement and maintenance of uniform rates, the cooperative model of custom hiring of agricultural machinery implemented in Punjab should be introduced in Tur growing regions of Karnataka.

Abstract
Consumers have become more aware of safe food produced with low environmental impact in which organic agriculture is of particular interest in this respect. The possible differences between organic and conventional plant products are examined from the view of possible effects on human health. However there can be considerable risk that the avoidance of chemical inputs in organic farming will result in poor food production. Agriculture must meet the twin challenge of feeding a growing population, with rising demand of high calorie diets, while simultaneously minimizing its global environmental impacts. Organic farming is a system aimed at producing food with minimal harm to ecosystems, animals or humans which is often proposed as a solution. Keeping in view of sustained crop yields as well as soil health, an experiment was conducted at Agricultural Research Station, Vizianagaram, Acharya N. G. Ranga Agricultural University, Andhra Pradesh, during Kharif 2015-16 to study the effect of complete organic method of farming in comparison to conventional method on soil health, yield and quality of little millet crop. The organic inputs were supplied in the form of green manures (Sunhemp), farmyard manure, neem cake and biofertilizers (Azospirillum and Phosphorus Solubilising Bacteria) whereas the conventional method by application of recommended dose of inorganic fertilizers (20-20-20 kg NPK/ha). The results revealed that significantly highest number of spikes/plant (14.1), grain yield (6.7 q/ha), straw yield (69.6 q/ha) and N uptake (62.1 kg/ha) and K uptake (33.48 kg/ha) were recorded in inorganic treated plot when compared to the organic plot (10.1, 5.0 q/ha, 58.6 q/ha, 50.2 kg/ha and 27.21 kg/ha respectively). Whereas the soil available macronutrients and micronutrients were found highest in the organic treated plot but there was no significant difference between the organic and conventional plots.

Abstract
The paddy variety MTU-1075 was recorded higher plant height (98.1 cm), effective tillers hill-1 (21.5), length of panicle (24.1 cm), grains panicle-1 (248) and test weight (23.65 g) than the local check (RGL-2538). The same also recorded grain yield 50.87 q ha-1 which is 38.52% higher yield than local check (RGL-2538) with harvest index of 47.2% over the years of study. In spite of increase in yield of improved technology the technological gap, extension gap and technology index existed which was 5.43q ha-1, 19.55q ha-1 and 10%, respectively. The improved technology of paddy variety gave higher gross return of ₹ 75000 ha-1 with a benefit cost ratio of 3:1 and additional net return of ₹ 25277 ha-1 as compared to local check. Hence the existing medium duration paddy variety RGL-2538 (Vasundhara) can be replaced by medium duration paddy variety MTU-1075 (Pushyami) since it fits to the existing farming situation for higher productivity and income.

Abstract
An experiment was conducted with sixty genotypes of fennel for phenotypic characterization of different vegetative characters such as plant height, branches per plant, primary branches per plant, secondary branches per plant, umbels per plant, umbellate per plant, seeds per umbellate, seeds per umbel and seed yield. Variability observed for quantitative traits showed high range variation for plant height, umbels per plant, umbellate per plant, seeds per umbellate, seeds per umbel and seed yield. Characterization of germplasm based on morphological parameters signifies the extent of variability present in the population and also provides needful information for selection of desirable genotypes for varietal development and also genotypes which can be conserved for unique traits. The identification keys based on morphological characters are very useful for identification of genotypes and have a pivotal role to identify genotypes in the field without any use of costly chemicals and are fairly comparable with their results.

Abstract
In the present study 21 tomato genotypes were used for association analysis in twelve plant characters. Correlation studies explained that fruit yield had positive and highly significant correlation with relative water content (RWC), membrane stability index (MSI) and lycopene content at both phenotypic and genotypic level. Path-coefficient study at genotypic level revealed that RWC, chlorophyll ‘a’, proline, lycopene and acidity had high positive direct effect on yield whereas chlorophyll ‘b’, total chlorophyll, chlorophyll a/b ratio, TSS and ascorbic acid had negative direct effect on yield. This showed the degree for development through direct selection for these characteristics and it might be very viable as these characters are less impacted by environment. Based on the physiological and biochemical parameters the genotypes Pusa Sadabahar, Balkan, TH-348-T2 and LP-2 were selected as superior thermo tolerant tomato genotypes.

Abstract
In remote tribal areas of the country, still electrification is yet not reached. To overcome the problem of increasing cost of generating electricity by advanced method, some cheaper method is to be introduced in those areas. Keeping in view the above, rotary mode unit run by a pair of draught animal i.e. bullocks is the best option to generate electricity. Draught animals are used for 50-60 days for agricultural operations and the rest of the period is idle for them. Thus this will also increased the utilization of draught animal power in the country. During the study, walking speed of bullock, draught and power output developed by bullocks was observed at an interval of one hour for the span of seven hours of working. The rotary unit of size 74 × 48 × 38 cm having a set of spur and bevel-pinion gear was used through universal shaft and belt pulley arrangement. The average speed of bullocks during work was found to be 3.23 kmph and the power output developed by bullocks during electricity generation and battery charging was found to be 0.264 KW. The physiological responses of animal in terms of pulse rate, respiration rate and body temperature were recorded during the work increasing with advancing of working time. During seven hours of work the animal body temperature, respiration rate and pulse rate were increased up to 44oC, 51 blows/min and 68 bpm at load condition. The animal power output reduced with passage of time. Battery used for the experiment was 20 AH, 13 plates and 12 voltages, which was charged up to 11.5 volt and its specific gravity was observed 1250 during 7th hour of working. The total cost of electricity generation and battery charging was found ₹ 40.00.

Abstract
The study was conducted at Durg block in Durg district of Chhattisgarh where banana is an important fruit crop. A sample of 60 respondents in the ratio of 20:20:20 was selected randomly. The respondents were classified into three groups viz. small (>2.00 hectares), medium (2.01-4.00 hectares) and large (4.01 hectares and above) farms. It was found that the problem faced by the sample farmers in the production and marketing of banana were problem in obtaining quality seed at reasonable price and higher prices for human labour and fertilizer inputs. Higher human labour input cost due to lack of management and high rate of human labour per days because constraint of human labour. And high fertilizer cost due to lack of market yard and reasonable price and also lack of credit facilities for securing crucial inputs at reasonable prices was not funded timely to banana growers through institutional financing agency. Some important constraints found in banana marketing such as price fluctuation in banana marketing lack of market information, lack of storage facilities, lack of processing industries based on fruit, lack of government facilities in marketing of banana.

Abstract
Guava is known for its flavour and nutritional value. Being climacteric and soft in nature its storage and export to other countries is a difficult task. Chitosan is the major bi-product produced from crustaceans shell waste, which can be utilized for the purpose of extending storage life of horticultural produce. In this paper, we have studied the effect of chitosan coating on physiochemical properties of guava stored at critical low temperature (8°C). The fruits were either treated with chitosan (1% and 2%), Acetic acid 1% or untreated and various quality attributes were studied at successive intervals of storage. The chitosan 1% treated fruits showed delayed ripening, reduced respiration rate with retention of higher firmness and acidity. The physiological loss in weight and total soluble solids were recorded low in chitosan treated fruits when compared to other treatments. Thereby, Chitosan 1% was able to extend the storage life of guava up to 35 days when stored at 8°C and showed good quality even 2 days after shifting to room temperature.

Abstract
An experiment was conducted during 2012-13 at Vegetable Section, Department of Vegetable Science, College of Horticulture Arabhavi, on combining ability studies in bitter gourd for quantitative characters by using six lines and four testers in a line × tester mating design. Except two characters (number of primary branches and fruit yield per vine) significant differences were observed for the characters under study. Variances due to SCA were higher than the corresponding GCA for all the characters except for vine length at 60 and 90 DAS, it indicates predominance of non additive gene action and there is a scope for heterosis breeding. Out of ten parents Panurthy, Coimbatore Long, Chidambaram Small and VRBT-100 were observed to be best general combiner as they have made significant contribution in yield contributing characters. Coimbatore Long × Panurthy exhibited high SCA effect for fruit yield per vine, node at first female flower appearance and days to first harvest, VRBT-100 × Panurthy is best for days to first male and female flower appearance, Coimbatore Long × Panurthy is best for sex ratio and number of seeds per fruit in desirable direction.

Abstract
Comparative study of three types of manual weeder namely wheel hoe, crescent hoe and dry land weeder were ergonomically evaluated for women farm workers. The different physiological parameters like heart rate, oxygen consumption, energy expenditure and posture parameters like average twisting velocity, maximum sagittal flexion, maximum lateral velocity, body part discomfort and overall discomfort were evaluated for operator operating each weeder. The highest heart rate, oxygen consumption and energy expenditure of worker were observed in the operation of wheel hoe. Working with wheel hoe and dry land weeder were categorized as “heavy work” with heart rate 114 and 112 beats per minutes respectively. The subjective evaluation of body part discomfort and overall discomfort score for subjects operating wheel hoe were higher among all the weeder (31.01 and 2.51). The field capacity of wheel hoe was highest (150m2h-1). The ergonomic evaluation of wheel hoe, crescent hoe and dry land weeder were done and found that field capacity and energy expenditure were high; therefore there is need of modifying the existing weeder to make it compatible for women farm worker. Modifications in the existing weeder according to anthropometric and physiological parameters of female workers can reduced the energy consumption and body deviations between work and thus enhanced work output.

Abstract
Distillery spentwash a wastewater discharged by distilleries can be utilized as a nutrient rich resource for crop production. In order to study the impact of different dilutions (1:1, 1:5, 1:10, 1:20 and 1:40) of spentwash application on growth and yield of paddy a pot experiment was conducted mainly to identify the best dilution for paddy crop. Results revealed that the growth parameters like plant height, number of tillers and number of panicles were highest with lower dilutions (1:1 and 1:5) of spentwash compared to higher dilutions (1:20 and 1:40). Yield parameters like number of filled grains per panicle was highest in higher dilution (1:40) and was on par with 1:20 dilution which decreased significantly with decrease in dilution levels. Application of distillery spentwash at 1:40 dilution recorded significantly higher yield (26.80 g pot-1) followed by 1:20 dilution (T4) 21.58 g pot-1. With respect to soil properties, significantly higher soil pH and Electrical conductivity was recorded in T1 (1:1 dilution) compared to initial values. Significantly highest organic carbon content was recorded in T1 (1:1dilution) but was on par with 1:5 times diluted spentwash. The available N, P and K content of soil increased with increase in the proportion of effluent confirming the fact that the effluent contained the above mentioned nutrients in sufficient amounts. The exchangeable sodium content was highest in treatment with lower dilutions and decreased with higher dilutions. The nutrients present in spentwash offer an excellent opportunity to use it as a liquid fertilizer along with irrigation water to achieve higher yields of crops.

Abstract
The present study was conducted in outdoor cemented ponds comprised of three factors i.e. two supplementary feeds (D1, routine diet vs. D2, diet supplemented with vitamin-mineral mixture @ 2%), two feeding rates (R1, 3% BW vs. R2 4% BW) and two feeding frequencies (F1, once-a-day vs. F2, twice-a-day feeding). Thus, there were 8 treatments combinations viz. T1: (D1, R1, F1), T2: (D1, R1, F2), T3: (D1, R2, F1), T4: (D1, R2, F2), T5: (D2, R1, F1), T6: (D2, R1, F2), T7: (D2, R2, F1) and T8: (D2, R2, F2). The diets were fed for a period of 8 months and the effect of different treatments on biochemical composition of flesh in terms of total proteins, total lipids, total carbohydrate, ash and moisture of fish from each treatment was analyzed during the pre-spawning (July) and post-spawning/resorption (September) period. During pre-spawning period, flesh protein content was maximum in T8 (12.78%) and minimum in T7 (11.71%), total lipid was maximum in T6 (1.53) and minimum in T5 (1.15), total carbohydrate was maximum in T8 (2.58%) and minimum in T1 (2.13%), moisture content was maximum in T8 (80.49%) and minimum in T1 (77.76%) and ash content was maximum in T1 (1.77%) and minimum in T8 (1.33%) and the difference among all the treatments were significant. During post-spawning/resorption period, the flesh protein content was maximum in T8 (13.10%) and minimum in T7 (12.12%), total lipid was maximum in T6 (1.81%) and minimum in T5 (1.35%), total carbohydrate was maximum in T4 (2.86%) and minimum in T7 (2.38%), moisture content was maximum in T7 (79.55%) and minimum in T1 (77.25%) and ash content was maximum in T1 (1.64%) and minimum in T8 (1.37%) and the difference among all treatments were significant. Not much difference was recorded in different parameters during pre-spawning and post-spawning period. In contrast, total carbohydrate content in fish increased with increase in feeding rate, feeding frequency as well as supplementation of vitamin mineral mixture in the diet. Similar trends were related in case of moisture content, while ash content decreased in fish fed twice with vitamin-mineral supplemented diet at both the feeding rates (3% and 4% BW). Overall results of vitamin-mineral supplementation of diets and feeding regimes was not found to have any positive effect on the flesh quality of fish.

Abstract
The experiments were conducted in the Plant Pathology Field and Glasshouse at Indira Gandhi Krishi Vishwavidyalaya, Raipur Chhattisgarh in the year 2014-2015 to study the effect of soil type, cropping sequence/crop rotation and intercropping on Albugo bliti incitant of white blisters of Amaranthus bicolor. This experiment was conducted to know the effect of soil type. Four major soil type found in the Chhattisgarh state were used in the present investigation, different soil type viz. Entisol (Bhata), Inceptisol (Matasi), Alfisols (Dorsa) and Vertisols (Kanhar) were taken. The pot experiment was conducted in glasshouse. Revealed maximum disease severity in Dorsa soil (12.14%) followed by Matasi (11.49%), Bhata (9.84%) and least in Kanhar (6.29%). Disease severity in Dorsa and Matasi soil was statistically at par while disease severity in Kanhar soil was significantly lower as compared to other soils. Cropping sequence with non-host crop decreases the disease severity significantly in comparison to that of control. Significantly lowest disease severity was recorded in Methi-Methi-Amaranthus but disease severity in Methi-Coriander-Amaranthus and Coriander-Coriander-Amaranthus was at par with each other. It also appears that disease severity was lower when Methi was included in the cropping sequence. Influence of intercropping on white blister disease severity of Amaranthus. Disease severity was recorded on 20 randomly selected plants twice - first 15 days after sowing and second before harvest (30 days after sowing). All the experiments were repeated thrice on same plots in same season. From the result, Amaranthus + Palak intercropping was found better among other intercropping combinations. This might be due to less secondary spread of inoculum in field conditions due to in presence of Palak foliage.

Abstract
An experiment was carried out during March 2015 to January 2016 at farmer’s field, Thiruvananthapuram, Kerala, India, to evaluate the economic feasibility of land management practices, time of lime application and fertigation in banana (var. Nendran) cultivation. The variation between land management practices for precision farming and conventional cultivation and different time of lime application did not impart any significant influence on banana yield and economic parameters viz. gross income, net income and B:C ratio. The different fertigation levels positively influenced the bunch weight plant-1, yield ha-1 and economics of production over soil application. In soil with medium N and K and high P levels, the fertigation levels of 100% and 60% recommended dose (RD) of N and K (300g N plant-1; 450g K plant-1 and 180g N plant-1; 270g K plant-1, respectively) applied at weekly interval along with soil application of P (86.25 g P plant-1) were observed to be on par and superior to 140% RD (420g N plant-1; 630g K plant-1) on yield and economics.

Abstract
Soybean categorized as poor storer because a rapid loss in viability occur under warm and humid conditions. Under warm and humid condition oil seeds become susceptible to storage fungi. The seed of soybean varieties PS 1347, PS 1042, PK 472 and PK 262, obtained from Crop Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar were used for this study. All parameters taken under this study decreases as the accelerated ageing period increases but at varied level in different varieties of soybean. All characters were affected by accelerated ageing in all varieties. Less adverse effect of accelerated ageing was imposed in variety PS 1042 followed by PS 1347 while maximum in PK 472 and PK 262. This indicate that variety PS 1042 can tolerate the ageing conditions with less effect on studied parameters, thus can be stored for longer duration, variety PS 1347 considered as medium storer and PK 472 and PK 262 as poor storer.

Abstract
Present study deals with the cost and return of sugarcane in Balod district of Chhattisgarh. 150 sugarcane growers were selected randomly from 5 blocks and were categorized into marginal, small, medium and large farmers based on their holding size. The primary data were collected for the year 2014-2015. The study observed that the average size of farm was 2.80 hectares. The tube well was observed as major source of irrigation as irrigated area was found to be 46.72 per cent. On an average, the cost of cultivation of sugarcane was amounted as ₹ 88153.85 per hectare. The major share of cost of cultivation gone to labour cost hired and family being 40.38 per cent of the total cost. The gross return obtained 171315.67 and net return against the cost of cultivation was observed ₹ 83161.82 per hectare. The input - output ratio of sugarcane came to 1:1.94. The study suggested that during peak period of agricultural operations the unavailability of sufficient labour and available at very high cost. To avoid the escalation of cost and better use of inputs mechanization may be encouraged.

Abstract
Potassium releasing power of ten soils of West Bengal and Jharkhand evaluating through step K and constant rate K showed that K release reached plateau at 4th to 6th number of extractions indicating variability of K availability to plants. Step K ranging between 9.40 to 22.74 mmol (p+)/kg exceeded the amounts of non exchangeable K in all soils and expected to be non-responsive to K fertilization for longer duration. Constant rate K varied from 0.25 to 0.44 mmol (p+)/kg and expected low to moderate K supplying power under stress. Cumulative K release varied within 11.40 to 26.26 mmol (p+)/kg soil. All these forms of K showed significant positive correlations with exchangeable, non exchangeable and lattice K. These suggest that there is need to apply moderate doses of fertilizer K at regular interval for optimum plant K nutrition.

Abstract
The study was conducted to know the resource use efficiency and resource use pattern in BT cotton cultivation in Dharwad district of Karnataka. In Dharwad district 3 villages were selected randomly such as Heballi, Narendra and Shivalli. From each village, 10 respondents growing BT Cotton were selected thus making a total sample of 30. To estimate the resources use efficiency Cobb-Douglas production function was employed and Allocative efficiency = MVP/MFC In order to determine the efficiency of allocation of the resources or price efficiency. The analysis of input utilization clearly indicates that the labour utilization was more because of the number of picking was more. With respect yield obtained in study area was 27.25 quintal of main product (Kappas) and 46.61 quintals of by product. The regression coefficient of fertilizer (0.31) and PP Chemicals (0.21) are significant hence it indicating increase in the use of these resources over and above the present level lead to a significant increase in gross returns. Whereas, the resources in study area was over utilized but are still in the rational region of production Except seed and FYM because these two are beyond the rational region hence there is need of optimal use of resources.

Abstract
In many agricultural systems around the world, competition from weeds is one of the major factors reducing crop yield and farmers’ income. In developing countries, herbicides are rarely accessible at a reasonable cost, hence farmers often need to rely on alternative methods for weed management. Worldwide limited success in weed control is probably the result of an over-simplification in tackling the problem. Too much emphasis has been given to the development of weed control tactics (especially synthetic herbicides) as ‘the’ solution for any weed problems, while the importance of integrating different tactics (e.g. preventive, cultural, mechanical, and chemical methods) in a cropping system-based weed management strategy has long been neglected. Integrated weed management is based on knowledge of the biological and ecological characteristics of weeds to understand how their presence can be modulated by cultural practices. As such, the interactions between weed management and other cultural practices must be duly taken into account. Integrated weed management uses a variety of control techniques to keep the weeds “off balance” in a sustainable manner.
