Effect of Gibberellic Acid and Cycocel on Growth, Yield and Protein Content of Pea
R.K. Bora and C.M. Sarma

Abstract: A study on the effect of pre-soaking treatments of Gibberellic acid (GA3) and Cycocel [(2-Chloroethyl) trimethylammonium chloride] singly on growth, yield and protein content of pea (cv. Aparna and Azad-P-1) was carried out in a randomized block deign with three replications. Fertilizers used at recommended doses and pH was adjusted at 6.0. Concentrations of PGRs used 10, 100, 250, 500 and 1000 μg mL-1 with a control set. Length of shoots was measured at an interval of 3 days from 7 DAS. Number of branches was recorded at an interval of 7 days from 15 DAS. Chlorophyll estimation was done on 30 DAS. Yield attributing characters were recorded at proper time. Protein was estimated from harvested seeds. GA3 irrespective of concentrations was most effective in promoting shoot growth while cycocel at all concentrations tried reduced shoot growth. Number of branches per plant was increased with both the hormones. In both the varieties chlorophyll contents were decreased by higher concentrations of GA3 while cycocel increased it. Both the hormones significantly affected the yield characteristics. GA3 at 250 μg mL-1 produced maximum number of pods per plant, seed yield, seed index and protein content in seeds in both the varieties. Cycocel at 100 and 250 μg -1 mL recorded maximum number of pods per plant and seed yield in cv. Azad-P-1 and cv. Aparna, respectively. Protein content in seeds was recorded highest at 500 μg mL-1 of cycocel. The present study clearly shows that judicious application of GA3 and cycocel can increase yield and protein content in seeds of pea.
