EFFECT OF GIBBERELLIC ACID AND GYPSUM ON GROWTH AND YIELD OF GROUNDNUT (ARACHIS HYPOGEA L.)JANGA HARSHA VARDHINI AND SHIKHA SINGHAbstract A field experiment was conducted during kharif 2020 at Crop Research Farm of SHUATS, Prayagraj to know the effect of Gibberellic and Gypsum on growth and yield of Groundnut. The experiment consisted of 12 treatments which includes 2 levels of gibberellic acid (GA3 50 and 100 ppm) and 3 levels of gypsum (200,250,300 kg/ha). The treatment receiving GA3 100 ppm produced significantly higher plant height (109.16cm), No. of nodules per plant (53.93), Plant dry weight (56.73g) and GA3 100 ppm +Gypsum 300 kg/ha produced significantly higher number of pods per plant (21.31), number of kernels per pod (2.10), Seed yield (2.68t/ha) and Haulm yield (4.37t/ha) however, Gross return (2,07,642.89 INR/ha), Net return (1,36,627.69 INR/ha) and B:C ratio (1.92) was also obtained maximum with the application GA3 100ppm +Gypsum 300kg/ha. This experiment showed treatment receiving GA3 100ppm+Gypsum 300kg/ha was more productive and economic. |
