Abstract: An experiment to study the effect of primers on growth and biochemical parameters of rice (Var. NDR-118) was conducted at Department of Crop Physiology, N.D. University of Agriculture & Technology, Kuma rganj, Faizabad (U.P.). Seed priming was done by soaking the seeds for 16 hours in distilled water, GA3 50 ppm, GA3 100 ppm, GA3 150 ppm, K2HPO4 300 ppm, K2HPO4 400 ppm and K2HPO4 500 ppm. Application of primers brought a considerable increase in growth parameters like root length, root and shoot dry weight. The biochemical parameters viz., total chlorophyll content, total soluble carbohydrate and nitrate reductase activity showed a significant increase due to seed priming. Among different treatments, GA3 100 ppm was the best treatment in increasing these parameters being at par with GA3 50 ppm and significantly higher than rest of the treatments.
Keywords: GA3, primers, rice, soluble carbohydrate, nitrate reductase
