Impact of Improved Technologies on Rice Productivity and Profitability at Nalgonda District, Telangana

Abstract

The present study was conducted during rabi season of 2017–18 and 2018–19 (November–April) to assess the performance of rice variety KNM 118 (Kunaram sannalu) over existing farmers’ popular variety MTU 1010 in fifty (50) number of farmers fields of Miryalaguda and Damaracherla mandals in Nalgonda District, Telangana, India under Tribal Sub-plan. Based on the collected data, per cent increase yield over the farmer’s practice, economics such as gross returns, cost of cultivation, net returns, additional costs, effective gain, additional returns and incremental benefit-cost ratio were worked out. The technology gap, extension gap and technology index were calculated. The results revealed that the average grain yield was 7297.5 kg ha-1 in improved practice which was a 12.1% increase over the farmer’s practice i.e. 6510.0 kg ha-1 during the study period. Mean of the extension gap, technology gap, and technology index were 787.5 kg ha-1, 202.5 kg ha-1, and 2.7%, respectively over the seasons. The average gross returns and net returns of ` 1,29,211.3 ha-1 and ` 76,812.8 ha-1, respectively were higher in demonstration plots as compared to farmer’s practices over the two seasons. The benefit-cost ratio recorded was 2.5 in improved practice, and 2.2 in farmer’s practices. The average sustainability yield index and sustainability value index in improved practice were 0.94 and 0.88 and in the farmer’s practice were 0.94 and 0.89 during the study period. The horizontal spread of the improved practice was increased from 107.5 ha to 1442.0 ha, which was 1222.8%.
