Hence, a study was taken up to find out the extent of adoption of hybrid rice seed production technologies by the respondents in Karimnagar district of Telangana state. The result of the study revealed that majority of the respondents had high extent of adoption followed by medium and low extent of adoption on hybrid rice seed production. Item analysis indicates majority of the respondents had adopted planting parental lines to come to flowering 21 days either prior or after the rice varieties grown nearby fields start flowering, practicing isolation distance of 100 mts followed by transplanting the seedlings at the age of 20-25 days, rouging at tillering, flowering and at maturity stage, A and R lines are grown in 10:2 row ratio, application of GA3 before flowering stage, clipping of flag leaf for wide spread of pollen grains, Clipping of flag leaf for wide dispersal of pollen grains to get higher seed yield, following chemical weed control with Butachlor @ 2.5 l/ha, least ranked practices were nursery beds should be top dressed with nitrogen @ 600-800 g per 100 m2 of area, following seed treatment in paddy with Carbendazim and applying recommended quantity of FYM on last puddling.
