Abstract:
A total of 275 no’s of frontline demonstrations on rice were conducted by Krishi Vigyan Kendra, Kampasagar during kharif season 2016 to 2019 at Nalgonda District, Southern Telangana Zone. The results revealed that grain yield was significantly high (6790.0 Kg ha-1) with 12.0 per cent yield superiority in demonstration plots over the farmer’s practice (6048.0 Kg ha-1) during the four years of the study period. The technology gap ranged between 0.0 Kg ha-1 to 350.0 Kg ha-1 with a mean of 210.0 Kg ha-1. The lowest and highest extension gaps were observed in kharif 2019 (518.0 Kg ha-1) and kharif 2018 (1050.0 Kg ha-1), respectively. The mean extension gap was 742.0 Kg ha-1and the technology index was in the range of 0.0% to 5.0% with a mean of 3.0%. The average plant height, number of tillers m-2, panicle length, and filled grains were high in improved practice as compared to farmers’ practice. Whereas, effective tillers m-2, chaffy grains panicle-1, test weight per 1000 seeds and straw yield were low in improved practice. These results based on the comparison between demonstrations and farmer’s practice indicated that the yield, gross returns, net income, and benefit-cost ratio were higher in frontline demonstrations than that of local farmer’s practice.
