Socio-Economic Profile of Sheep Farmers in Diverse Agro-Climatic Zones of Tamil Nadu: A Comparative Study
A study on the socio-economic status of sheep farmers was conducted in Tamil Nadu, India. From each of the five selected agro-climatic zones, eight blocks were selected randomly and from each selected block, two villages were selected randomly. From each selected village, five farmers were selected randomly constituting the total sample size of 400 sheep farmers. The data were collected by personal interview method with the help of pretested interview schedule. The study revealed that the nearly half of the respondents (48.50 per cent) belonged to the middle-aged category (above 35–50 years), majority of the respondents were male (85.50 per cent), half of the respondents (48.25 per cent) were illiterate, Cent per cent of the respondents reported sheep farming as their primary occupation, the majority of the respondents (68.50 per cent) belonged to the medium experience category (15.59 to 36.55 years), majority of the respondents (41.75 per cent) belonged to the small flock size category (up to 49 animals), 38.25 per cent of the respondents belonged to the low-income category (up to ₹5 lakhs per annum), an overwhelming majority of the respondents (99.75 per cent) preferred selling sheep through intermediaries or middlemen.. The study on socio-economic status of sheep farmers revealed that the sheep farming contributed to the livelihood security of rural households with different socio-economic background and inclusion of sheep farming in welfare scheme would improve the livelihood in rural areas.
Impact of Institutional Agricultural Credit on Farmers’ Income: A District-Level Panel Data Analysis of Andhra Pradesh
Institutional agricultural credit plays an important role in enhancing agricultural productivity and improving farmers’ income. The present study examined the impact of institutional agricultural credit on farmers’ income across districts of Andhra Pradesh using district-level panel data for the period 2010–2024. A balanced panel dataset comprising thirteen districts was constructed using secondary data collected from the Reserve Bank of India, National Bank for Agriculture and Rural Development, and Directorate of Economics and Statistics. Descriptive statistics, correlation analysis, panel unit root tests, and panel regression techniques were employed for analysis. The Hausman specification test confirmed the suitability of the Fixed Effects Model. The results revealed that institutional agricultural credit had a positive and statistically significant impact on farmers’ income. The coefficient of agricultural credit was positive and significant at p < 0.01, indicating that increased access to institutional agricultural credit contributes significantly to higher farmers’ income. Irrigation coverage, cropping intensity, and fertilizer consumption also positively influenced farmers’ income. The regression model explained 71 percent of the variation in farmers’ income across districts. The study concludes that strengthening institutional agricultural credit systems is essential for improving agricultural productivity and enhancing rural livelihoods. Policy measures aimed at ensuring timely and adequate institutional credit along with investments in irrigation infrastructure and efficient input utilization can significantly contribute to sustainable agricultural development in Andhra Pradesh.
Sustainable Management of Chilli Anthracnose (Colletotrichum capsici) using Plant Extracts from the Mid-Himalayan Region of Uttarakhand
The present investigation was under taken for the management of anthracnose chilli caused by Colletotrichum capsici using plant extracts in vitro and in vivo conditions. The study was carried out at College of Horticulture, VCSG UUHF -Bharsar, Pauri Garhwal during 2025-26. The pathogen was isolated from infected chilli fruits and purified for further studies. The experiment aimed to check the effect of various plant extracts on the mycelial growth of Colletotrichum capsici under in vitro condition. Seven plant extracts viz., Artemisia vulgaris, Acorus calamus, Rosmarinus officinalis, Cinnamon tamala, Tagetes minuta, Melia azedarach, and Cinnamon camphora were tested against C. capsici using Poison food technique at different concentration i.e. 5%,10% and 15%. Out of all the extracts, Rosemary showed maximum inhibitory effect to C. capsici recording (74.99 %) mycelial inhibition at 15% concentration followed by Artemesia (67.45%) inhibition under in-vitro condition. under field conditions Rosemary extract at 15% concentration recorded minimum per cent disease index (19.67%, 23.89%, 27.97%) and maximum disease control (71.08%, 69.23%, 68.13%) at 90, 105 and 120 (DAT) respectively. Based on the above findings, it is proved that spraying Rosemary @15% was the most efficient approach to minimize plant disease intensity.
Efficacy of Hormonal Therapy and Ultrasound guided Transvaginal Follicular Aspiration for Non-Responsive Follicular cysts in Jersey crossbred cows
The occurrence of ovarian follicular cyst has significant effects on the reproductivity in cattle and lead to economic loss. The objective of this study is to investigate the efficacy of hormonal therapy for treating follicular cysts to improve the fertility in crossbred cows and the application of ultrasound guided transvaginal follicular aspiration technique in non-responsive chronic follicular cysts. A total of 28 crossbred cows with follicular cysts were included in the study and were treated with GnRH analogue @ 20μg intramuscularly on day 0. The cows which responded to first GnRH injection (16/28, 57.14%) having corpus luteum on day 11 were termed as Group I (n=16). Group I cows were treated with Co-synch protocol. The cows which did not respond to first GnRH having persistent cyst on day 11 were termed as group II (n=12) and received second GnRH injection. Only seven cows responded for second GnRH injection (7/12, 58.33%) and the rest of the protocol was followed similar to that of group I. Three among the five cows exhibited estrus and were re-inseminated. Ultrasound guided transvaginal follicular aspiration was performed for remaining five non-responsive cows in group II. Pregnancy diagnosis on day 60 post AI revealed nine out of sixteen cows were pregnant (9/16, 56.25%) in group I and three out of seven were pregnant (3/7, 42.85%) in group II responded cows. However, the recurrence of fluid accumulation in the follicular cyst were recorded in two cows (2/5, 40.00%) and three cows had recovered (3/5, 60.00%) following follicular aspiration and later one cow was pregnant. The overall pregnancy rate in group I, group II, hormonal therapy and follicular ablation were 56.25%, 33.33%, 52.17% and 20.00%, respectively. The ovarian follicular cysts were characterized by higher levels of BUN, calcium and lower levels of glucose, cholesterol, total protein, albumin, creatinine, AST and phosphorus. Hence, in the cases of failure of hormonal therapy, ultrasound guided transvaginal follicular aspiration technique can be advocated for the management of chronic and non-responsive cystic ovarian follicles in dairy cattle.
Unravelling the Drivers of Entrepreneurial Behaviour: A Structural Equation Modelling Approach in Agriculture
This study explores the interplay between self-efficacy, entrepreneurial climate, technology awareness, entrepreneurial orientation, and entrepreneurial behaviour among youth in the states of Uttar Pradesh and Haryana. Using a structured questionnaire and Partial Least Squares Structural Equation Modeling (PLS-SEM), data from a purposive sample was analyzed to test six hypothesized relationships. Results reveal that self-efficacy (β = 0.477, p < 0.001) and entrepreneurial climate (β = 0.387, p < 0.001) significantly influence entrepreneurial orientation, while entrepreneurial orientation strongly predicts entrepreneurial behaviour (β = 0.550, p < 0.001). Moreover, entrepreneurial climate also has a positive impact on self-efficacy (β = 0.440, p < 0.001). However, technology awareness showed no significant effect on either entrepreneurial orientation or self-efficacy. The model explains 54.6% of the variance in entrepreneurial orientation and 30.3% in entrepreneurial behavior. These findings underscore the importance of fostering a supportive entrepreneurial climate and enhancing self-efficacy to encourage entrepreneurial engagement. The study offers implications for policy makers and educators to strengthen entrepreneurial ecosystems settings.
