Adoption Strategies and Assessment of Yield Gap Analysis of Rice in Mandya District of Karnataka

摘要

A study was conducted in Mandya district of Karnataka during 2016 and 2017 to assess the rice yield gaps and to know the adoption strategies opted by rice farmers of Mandya district. One hundred respondents were selected to study the current status ofadoption strategies, magnitude of rice yield gaps and strategies to narrow the gaps for sustenance of rice production in Karnataka. The selected farmers were interviewed using a pre-tested interviewed schedule. The results of the study revealed that among different rice varieties, majority of the rice growers were adopted medium duration varieties like MTU 1001 (51.85%), IR-64 (12.96%) and Thanu (11.11%) during the year 2016 and 20% of the farmers were grown different varieties viz; JGL, Super aman, Omkar, Siri, Sonamasuri, Rajamudi followed by BR 2655 (16%), IR-64 (14%) and MTU 1001 (13%). The cost for production of paddy was ranged betweenRs 35,000 to 57, 500 per ha. The yield gap between farmers average yield and potential yield of demonstration was about 30.55%. The farmers obtained almost on par yield with package of practice during both the years. Scarcity of labor during peak period,high cost of labor, non-availability of hybrid seeds, lack of irrigation facilities and lack of electricity to irrigate during critical growth period were the constraints expressed by the farmers during the study.
