The research was conducted in Ri-Bhoi District of Meghalaya in all three blocks using probability proportionate to population size. Yield gap was calculated based on the difference of potential farm yield and actual farm yield. Cobb-Douglas production function was applied to know the factors associated with the yield gap of rice. Ranjit cultivar and Lahi cultivar were found to have the highest yield gap among the major rice cultivars in Meghalaya. The yield gap was found to be high in Meghalaya which may be due to lack of technical knowhow, lack of new technology for cultivation of rice and non-availability of irrigation. There are many scope to improve the productivity of different cultivars by filling the yield gap through the use of new technology for the cultivation of rice in the state. Further research suggests to popularised Pasyrbhuh, Ranjit and Lahi which have more actual yield. The gap in yield of these cultivars must be reduced by refinement through research intervention. Input use of seed and human labour were found to be positive at 1 per cent level of significance in accelerating the yield gap in the state. Farmers should be trained about the use of seed of rice for its quantity, quality, germination etc. and same time rice cultivation is very labour intensive, hence introduction of new small machine will help to reduce/bridge gap of rice.
