The effectiveness of an extension organization can be defined as how well it performs its activities to attain the pre-determined objectives. In this present context KVKs are a key organization for transfer of technology based advisory services to the farmers at district level. The present study was conducted purposively in Chhattisgarh state, with a view to evaluate perceived effectiveness of Krishi Vigyan Kendra by the beneficiary farmers in utilization and accessibility of extension service delivery. Chhattisgarh comprises of three agro-climatic zones, out of that one district were selected randomly from each agro-climatic zones. From each selected district, 40 KVK beneficiary farmers were selected randomly which constitute a total sample size of 120. An ex-post facto research design was used for this study. The effectiveness of the extension organization (KVK) in technology advisory and delivery services was measured by effectiveness index developed for this purpose. The extension services rendered by KVK were found to be medium and low in effectiveness by majority (39.17%) of the farmers. About 11.70 percent of the farmers found the extension services is highly effective, with a mean effectiveness of 41.19±14.36. Extension services rendered by KVK were found to be medium in effectiveness by major share of the farmers followed by low in effectiveness. KVKs is the key institutions at the district level for transfer of technologies leading to a transformation of the agricultural and allied sector in the country. The constant extension and advisory support in addition leads to better adoption of technologies which further leads to increase in yield and income and ultimately satisfaction of the farmers towards the extension service.
A complete 3x3 diallel cross experiment involving 3 chicken breeds namely Aseel Peela (AP), Kadaknath (KN) and CARI-Red (CR) were used for comparison of performance of pure and crossbred chickens for body weight gain and to estimate the relative importance of different types of gene action involved in the inheritance of these trait. The chicks were brooded up to 6 weeks of age in four tiers battery cage brooder then shifted to deep litter and managed with ad libidum feeding and watering. Gain in body weight was calculated at biweekly interval up to 20 wks of age. Further, data were subjected to combining ability and other effects analysis using important models namely, Griffing (1956), method 1 under model 1. Among the purebreds CR had higher body weight gain in male, female and combined sex at 0 to 20 wk of age except, at 15-16 and 19-20 wk of age AP had higher body weight gain in combined sex. Among the cross bred, cross AP x CR had highest body weight gain in combined sex at 0-8, 0-16 and 0-20 wk of age. The analysis of variance between mating revealed highly significant difference at all ages of measurement except at 11-12 wk of age, among genetic groups are also revealed highly significant difference at all ages of measurement in male, female as well as combined sex. It was observed that the overall performance for body weights gain in crossbred were significantly better than the pure bred performance. Body weight gain revealed highly significant difference for general combining ability (GCA) at all ages of measurement in male, female and combined sex except, at 17-18 wk of age in female. However, Analyses of variance for specific combining ability (SGA) revealed highly significant difference in irrespective of sex at all ages of measurement except, at 5-6 wk of age in female, 11-12 wk of age in male, female as well as in combined sex and at 19-20 wk of age in male and combined sex. Reciprocal effects were also significant at all the ages of measurement irrespective of sex except at 11-12, 15-16 and 19-20 wk of age in male. CR had higher and positive GCA estimates. While, lowest and negative value was observed in case of KN. The cross AP x KN had positive and highest value of SCA as well as reciprocal effects in case of male, female and combined sex at all the age of measurements.
The sustainable production of agricultural crops in the Mid-Hills of Himachal Pradesh requires efficient resource allocation strategies. This study aims to investigate and propose measures to enhance resource allocation strategies for sustainable crop production in the region. A comprehensive study was conducted, utilizing a combination of quantitative analysis and filed surveys. The research focused on understanding the current resource allocaation practices, identifying areas of inefficiency, and exploring potential solutions to enhance sustainability. A multistage random sampling technique was employed to select a sample of farmers involved in crop production. The study revealed that existing resource such as seeds, fertilizers, labor, and irrigation. Furthermore, the study analyzed the relationship between various variables and resource utilization efficiency. Results indicated that variables such as rainfall, land area, literacy index, and crop yield index demonstrated a positive relationship with resource utilization efficiency. Conversely, crop diversification exhibited a negative relationship with efficient resource allocation. Based on the findings, recommendations were formulated to enhance resource allocation strategies for sustainable crop production. These recommendations emphasized the importance of providing farmers with additional technical knowledge and training to optimize resource utilization. By addressing the knowledge gap and promoting access to extension services, farmers can make informed decisions regarding resource allocation, leading to increased production and improved returns on major agricultural crops.
Implementation of moisture stress tolerant maize is one of the way to achieve sustainable production which will secure food for feature generation. On account of that, this study has objective to estimate general combining ability (GCA) and specific combining ability (SCA) of developed hybrids under moisture stress. The study was undertaken at M.P.U.A.T. Udaipur, Rajasthan from 2015‒2017. 45 hybrids were generated from 15 inbred lines with 3 testers and 4 commercial checks utilizing L x T design. These were evaluated in RBD under 3 managed environments with 3 replications each in 2015‒16 rabbi to avoid rainfall in order to estimate the effect of well-watered and moisture stress imposed at different stages on physiological and yield contributing characters of corn. Studies were conducted on only well-watered and managed stress but we developed 3 different environments and tried to make accurate effect of moisture stress on both important stages (i.e. at tasselling and grain filling). That’s why irrigation was regulated at tasselling E2 and grain filling E3 stages which targeted for giving moisture stress for 20 days at starting of both stages while E1 was well-watered. The low significance of GCA and SCA observed revealed the importance of dominant gene action while high GCA / SCA implies both additive and non-additive gene action. Drought stress reduces GY, Chlorophyll content, RWC, LA in both environments E2 and E3 and increases ASI, Proline content, LCT, LDS in E2 when compared with E1.
The poultry industry is actively seeking effective strategies to optimize feed utilization and improve efficiency. One area of growing interest is the impact of feed particle size and form. Pelleting offers advantages such as reducing ingredient segregation, improving feed flow, and allowing for cost reduction through alternative ingredient incorporation and reduced dietary energy. Cold-press pelleting, which eliminates the need for steam, addresses cost concerns and serves the intended purpose. In this study, the effects of cold-press pellet and mash feed on the production performance of laying hens during their peak laying period were investigated. Ninety-six commercial white leghorn layers were divided into two experimental groups: one fed a mash diet (MD) and the other a pellet diet (PD). Each group consisted of six replicates with eight birds in each replicate. Isocaloric and isonitrogenous diets were provided to all groups, with the mash diet serving as the basis for formulating the cold-press pellet feed. Observations were made on feed intake, feed efficiency, egg production, and egg weight. The results indicate that feed form influenced laying performance, with the pellet diet (PD) outperforming the mash diet (MD) in terms of egg production, average egg weight, feed intake, and feed efficiency. Pellet diets showed positive changes in feed intake, egg weight, and laying rate, ultimately improving production performance. These findings provide support for the advantages of feeding cold-press pellets to commercial laying hens during their peak egg laying period. Overall, incorporating cold-press pellet diets can enhance production performance through improved feed intake, egg weight, and laying rate in commercial egg type chicken.
