Yield Gap Analysis for Enhancement of Rice Production and Productivity under Rain-Fed Condition of Chandel, Manipur, India

Abstract

The study was conducted at Chandel district, Manipur state aiming to assess the impact of rice production under Frontline Demonstration (FLD) in terms of yield, yield gap/extension gap, technological gap and economic gains during kharif season from 2018 to 2022. The present Front Line Demonstration on rice var. RC-Maniphou-13 was carried out by Krishi Vigyan Kendra, Chandel, ICAR-RC for NEH Region, Manipur Centre at 40 hectares in 92 farmers’ field of different villages. The result indicated that average grain yield of rice in demonstration field ranged between 57.60 to 60.60 q/ha whereas in farmers’ practices, it was 42.50 to 47.33 q/ha during demonstrated years. The percent increase in yield with Demonstration Practices over Farmers’ Practices ranged between 28.04 to 35.53. The yield gap/technological and extension gap were from 9.40 to 12.40 and 13.27 to 15.10 q/ha respectively. Similarly, technological index was decreased from 17.71 to 13.43 per cent during the study period. The benefit cost ratio was from 1.98 to 2.65 under demonstration, while it was from 1.09 to 1.91 under farmer practices. By conducting Front Line Demonstration on improved practices with HYV of proven technologies in farmers’ field, yield potential of rice enhanced to a great extent which increased in production and productivity, also the income level of farmers has improved the livelihood of farming community in the region by reducing the technology gaps.
