Abstract

Agriculture is the major user of the available fresh water, the decline in water availability affects agriculture productivity. Among the agricultural crops, rice is a major consumer of water, and slight changing in the water resources of India affect the rice yield. Pusa Basmati 1509 is a cultivar characterised by its shorter duration with a maturity span of 120 days in addition to its exceptional grain and cooking qualities. It is highly popular among farmers because of its shorter growth period that saves a significant quantity of irrigation water by saving at least three to four irrigations. Krishi Vigyan Kendra, Datia, Madhya Pradesh conducted 100 demonstrations in 40 ha. on rice with varieties Pusa Basmati 1509 for five consecutive years from 2017 to 2021 at farmers’ fields of village Kharag, Sanora, Barodi and Rajpur village in Datia district under NICRA project to find out the worth of this verity. The results of two years of studies revealed that the yield under demonstration plots was 4508 kg/ha as compared to 3919 kg/ha in traditional farmer practices plots. This additional yield of 588.80 kg/ha and the increase in average rice productivity by 15.03 per cent may contribute to the present rice requirement on a national basis. The average technology gap, extension gap and technology index were found to be 292.00 kg/ha, 588.80.00 kg/ha and 6.08 per cent respectively. An additional net return of Rs. 6337 was received from this variety which is 11.00 per cent more to the farmer’s practices. Fluctuating the sale price (Mandi rate) of rice during all years influenced the economic returns per unit area. Adoption of the improved package of practices in rice cultivation recorded a higher B:C ratio (2.51) as compared to farmers’ practices (2.32).
