Aneesha D. Dhalin dhalin.d@kau.in Seena R. Subhagan O. P. Reji Rani Dipak S. Khatawkar <p>This study aimed at finding out the efficacy of electrostatic sprayer on pest control in comparison with mist blower and air compression sprayer. Six pests were selected based on specific characteristics viz. integumental, movement and ecological niche. Energy use efficiency in production and application of pesticides used by different sprayers for the control of selected pests were quantified based on application efficiency, pre and post pest count and reoccurrence of pest infestation after spray. The greenhouse gas emission for the total energy usage for the corresponding quantity of pesticide were computed for all the selected sprayers. The energy use efficiency of electrostatic sprayer was found to be 1.5 times more than that of mist blower and 2 times more than that of air compression sprayers. The chemical usage by electrostatic sprayer was reduced by 65%, and that of knapsack mist blower was 35% with air compression sprayers. The corresponding greenhouse gas emission was only 20% for electrostatic sprayer and 65% for powered mist blower than that of air compression sprayers. The post pest count was almost nil in all the categories of pest while applying with electrostatic sprayer and the reoccurrence of the pest to the threshold level was minimum. This contributes a significant reduction in emission of CO<sub>2</sub> when considered globally, and ultimately contribute to mitigation of global warming.</p> 2020-09-25T00:00:00+00:00 ##submission.copyrightStatement## https://journalcjast.com/index.php/CJAST/article/view/30952 Weed Management Strategies for Enhanced Productivity in Groundnut 2020-09-25T04:41:25+00:00 T.

Dar Bilal Ahmad Lone Farooq A. Sheikh Umer Rashid Bhat <p>Genetic diversity study was conducted in 38 chickpea (<em>Cicer arietinum</em> L.) genotypes using Mahalanobis D<sup>2</sup> Statistics. The current research performed at FoA, Wadura Sopore, SKUAST-Kashmir in the rabi 2017-18. In the present study, total seven clusters have been formed and range of D<sup>2</sup> values is from 301.78 to 8477.71, cluster II includes maximum 12 genotypes after that cluster I having 9 genotypes, cluster IV having 6 genotypes, cluster Ⅲ and Ⅴ having 4 genotypes, cluster Ⅵ having 2 genotypes and cluster Ⅶ with 1 genotype. 959.33 to 8477.71 is the range of inter cluster distance. Highest inter cluster distance (8477.71) was found between the clusters, Ⅵ and Ⅶ followed by the clusters, Ⅳ and Ⅶ (5814.62), Ⅳ and Ⅴ (5807.441), Ⅴ and Ⅵ (4659.34). The minimum inter-cluster distance (959.33) possessed by clusters, Ⅱ and Ⅲ. After comprehending the intra cluster divergence it has been found that cluster Ⅳ has highest intra cluster distance (637.07) then cluster I (459.16). Since cluster Ⅶ includes only one genotype which indicates that there is no intra cluster divergence. Total nine traits have been evaluated, plant height registered higher divergence (49.25%) then pods plant<sup>-1</sup> (36.12%), days to 50% flowering (4.13%) and days to maturity (2.7%), secondary branches plant<sup>-1</sup> (3.24%), seed yield plant<sup>-1</sup> (1.28%) and primary branches plant<sup>-1</sup> (1.14%). The 100-seed weight (1.12%) and seeds pod<sup>-1 </sup>(1.02%) possesses less divergence. By considering above results the nine genotypes viz., IR-1, IR-3, IR-30, IR-20, IR-21, IR-10, IR-2, IR-7 and IR-31 have been recognized as desired genotypes for use in future breeding programme.</p> 2020-09-24T00:00:00+00:00 ##submission.copyrightStatement## https://journalcjast.com/index.php/CJAST/article/view/30954 Bio-effectiveness of Sabuj Gold as Organic Manure on Cabbage, Cauliflower and French Bean 2020-09-25T10:29:08+00:00 Eggadi Ramesh eggadiramesh@gmail.com Subhamoy Sikder Shibnath Basfore <p>The present experiment was laid out in randomized block design maintaining three replications during the <em>Rabi</em> season of 2017-18 on three major <em>Rabi</em> season crops <em>viz., </em>cabbage, cauliflower, and French bean under four treatment <em>viz., </em>Sabuj Gold as principle sole nutrient supplement with recommended organic and inorganic plant protection inputs as well as recommended standard crop-specific inorganic cultivation practice to evaluate the bio-effectiveness of SABUJ GOLD as main organic manure. The result showed that 100% Organic Manure (Sabuj Gold as a primary nutrient supplement) + full organic recommended certified inputs (plant protection measures) had a predominant significant effect on almost all the characters under study, specifically plant height (26.89 cm in cabbage, 45.32 cm in cauliflower and 55.24 cm in French bean), number of primary branches (7.84 in French bean), leaf quantitative parameters, individual head weight in cabbage (1.32 g), curd weight of cauliflower (1.31 g), pod weight (3.37 g) and pod per plant (46.34) in French bean, yield (32.37 t/ha in cabbage, 17.58 t/ha in cauliflower and 8.94 t/ha in French bean), ascorbic acid in cabbage (65.24 mg/100g) and total chlorophyll in cabbage (445.61 mg/100 g). However, 100% Organic Manure (Sabuj Gold as a primary nutrient supplement) + full recommended inorganic supplement (plant protection measures) showed a significant effect on multiple characters such as &nbsp;germination percentage (88.52 %) and ascorbic acid (31.62 mg/100 g) in cabbage, total chlorophyll (424.75 mg/ 100 g in cauliflower and 134.95 mg / 100g in French bean). From the above discussion, it could be concluded that Sabuj Gold as a substitute for inorganic plant nutrient along with organic or inorganic plant protection measures could be very effective in enhancement of important yield and quality-related characters of different commercially important vegetables.</p> 2020-09-25T00:00:00+00:00 ##submission.copyrightStatement## https://journalcjast.com/index.php/CJAST/article/view/30955 Development of Electrically Aerated Stove for Pyrolyzed Briquettes 2020-09-26T04:57:55+00:00 O. K. Fadele fadeleseyi@yahoo.com M. B. Usman O. C. Ariyo U. U. Emeghara D. O. Adelani D. O. Oloyede <p>In this study, an electrically aerated stove was developed using locally available materials. The performance of the stove was evaluated by utilizing briquettes produced from pyrolyzed jatropha shell and <em>Eucalyptus camadulensis</em> wood shavings. Thermal parameters such as thermal efficiency, power output, specific fuel consumption and burning rate were determined. The mean values obtained for the thermal efficiency, power output, specific fuel consumption and burning rate were 7.62 %, 1685 J/s, 0.2377 g/g, 330.90 g/hr respectively. The performance of the briquette stove was considered to not be suboptimal. The thermal efficiency can further be improved by proper insulation and adequate utilization of the heat generated in the combustion chamber.</p> 2020-09-26T00:00:00+00:00 ##submission.copyrightStatement## https://journalcjast.com/index.php/CJAST/article/view/30956 Impact of National Food Security Mission (NFSM) on Growth Rates and Decomposition Analysis of Pulses Production in India 2020-09-26T10:41:43+00:00 R. Nagarethinam r.naga014@gmail.com M. Anjugam <p>This paper investigates the trends in area, production and yield of major pulses in India by using component growth rate, Instability index and decomposition analysis during last twenty years. Further the study period has been divided into three periods based on the implantation of NFSM: Pre NFSM period I (1995 to 2006), Post NFSM period II (2007 to 2016) and Overall period (1995 to 2017). The result of CGR in total pulses revealed that the area (1.87%), production (3.58%) and yield (1.89%) registered highly positive significance with increased growth in period II. The yield growth rate was higher than area growth rate implying that the area allocation under pulses is increasing poorly even after NFSM scheme, while improvement in yield is there. The instability of total pulses production and productivity has first decreased and then increased in the overall period its shows increased growth. Among the major crops, the area effect was high in lentil production and by yield effect was high in gram production and the interaction effect was high in moong production during the overall study period. In case of total pulses, area and yield effects were positively higher and they were responsible for total pulses production.</p> 2020-09-26T00:00:00+00:00 ##submission.copyrightStatement## https://journalcjast.com/index.php/CJAST/article/view/30957 Diversification of Cropping Systems for Different Integrated Farming System Models under Irrigated Situation of Southern Telangana Zone, Telangana, India 2020-09-26T11:04:48+00:00 Ch.

S. Dana S. B. Ramya Lakshmi <p>The present study was conducted to assess the empowerment level of women in the fisheries sector in the Ganjam district of Odisha. In the inland sector, the highest numbers of women are of the fishermen population in Ganjam district i.e. 29476 out of a total 263514 number of female fisheries population of the state (Directorate of Fisheries, Government of Odisha, 2015). A very good concentration of women is involving in fisheries activities in this district. But when sector-specific cases are concerned, there are very few studies found where different dimensions of women empowerment through fisheries are discussed. The results revealed that the majority of the respondents (66.60%) in the Inland sector are grouped under a medium level of empowerment followed by low and high-level empowerment (16.70%). These results indicated that there is a significant move towards the empowerment of women in the case of inland fisheries. However, in the Marine sector equal percentage of respondents belonged to both medium and high levels of women empowerment i.e. each 30 (50.00%) and low level of empowerment was nil which indicates the level of empowerment in the marine fisheries activities compared to inland fisheries. With this background, the overall empowerment score was categorized into the low, medium, and high level of empowerment where a majority of the respondents (71.6%) were under the medium level of empowerment followed by the equal percentage of the low and high level of empowerment (14.2%). The composite score of empowerment of women is also encouraging. However, efforts are needed to bring women empowerment from medium level to a higher level. There is also a need to uplift a section of women who are still in the lower category of empowerment.</p> 2020-09-26T00:00:00+00:00 ##submission.copyrightStatement##
