Five kabuli chickpea genotypes and desi chickpea genotypes were grown during rabi season of 2010-11 at Student’s Instructional Farm of N.D. University of Agriculture & Technology, Faizabad. 0 ppm (control condition), 15 ppm and 30 ppm concentrations of GA3 were applied as foliar application at flower initiation stage (65-70 days after sowing) to the plants. Nitrate reductase enzyme and nitrite reductase enzyme activity were evaluated in leaves of chickpea genotypes at flower initiation stage, 50% flowering stage and at the time of maturity whereas total nitrogen content was estimated in pods of chickpea genotypes at 20,40 and 60 days after flowering. Both the enzyme’s activity was found highest at the flower initiation stage and lowest at the time of maturity. Total nitrogen content in chickpea pods was found highest at 20 days after flowering and lowest at 60 days after flowering. At the time of 50% flowering and maturity nitrate and nitrite reductase enzyme activity was found maximum in control condition whereas with the foliar application of 30 ppm of gibberellic acid, these enzymes gave better response at flower initiation stage. Total nitrogen content was found maximum with the 30 ppm gibberellic acid. Desi genotype IPC 2004-90 gave better response among all the genotypes regarding the enzyme activity and total nitrogen content.
