Effect of Technological Interventions on Rice Yield at Farmers' Field

Atar Singh, A. K. Singh and Lakhan Singh

Abstract

Rice is one of the most important food crop grown in Uttar Pradesh. It is grown in Indo-Gangetic plains in rice – wheat cropping system. The productivity of rice in the state continues to be quite low on account of several biotic and abiotic stresses besides, unavailability of quality seed of improved varieties and inadequate crop management. The analysis of results indicated that hybrid varieties registered yield advantage of 4.62 q/ha as compared to varieties grown by the farmers. Similarly appropriate cropping systems showed the yield advantage between 4.35 to 12.15 q/ha as compared to traditional practice by farmers. The trials on nutrient management registered gain up to 0.98 to 17.61 q/ha over the farmers’ practice of using old variety and traditional crop management practices. Resource conservation gave advantage of 8.67 q/ha over farmers’ practice of not using resource conservation techniques, weed management realized yield gain of 6.50 q/ha over farmers practices. It has been found that yield advantages can be attained in rice by the use of improved varieties, integrated nutrient management, resource conservation and recommended insect and disease management regime
