Abstract

The field experiment entitled “Effect of Plant Growth Regulator at different levels of Zinc on growth and yield of Groundnut (Arachis hypogea L.)”  was conducted during kharif season of 2021 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P). The  experiment plot was sandy loam in texture, nearly acidic in soil reaction (PH 6.9), low in organic carbon  (0.112%),  available  N  (278.93Kg/ha),  available  P(10.8Kg/ha)  and  available  K  (206.4Kg/ha).The experiment was laid out in Randomized Block Design, treatments of different  plant growth regulator levels (75, 100 and 125 ppm) and zinc levels viz.(20,25 and 30 kg/ha) were imparted in the experiment and were replicated thrice. The experiment was laid out in Randomized Block Design comprised of 3 replications and total 9 treatments viz. T1: (GA3)75PPM + 20 kg/ha ZnSO4, T2: (GA3) 75PPM   + 25 kg/ha ZnSO4, T3: (GA3) 75PPM+ 30 kg/ha ZnSO4, T4:(GA3) 100PPM + 20 kg/ha ZnSO4, T5: (GA3) 100PPM +25 kg/ha ZnSO4,  T6: (GA3) 100PPM + 30 kg/haZnSO4, T7: (GA3) 125PPM + 20 kg/ha ZnSO4, T8: (GA3) 125PPM + 25 kg/ha ZnSO4, T9: (GA3) 125PPM +30 kg/ha ZnSO4.  Results obtained indicated that there was significant increase in growth parameters at harvest viz., plant height (58.40cm), number of nodules/plant (59.77), dry weight accumulation(38.1g),and yield attributes viz., No.pods/plant(19.3), No.kernals/pod (4.3), seed index(44.50), seed yield (3169 kg/ha), Haulm yield (4747.3kg/ha) were recorded with the application of (GA3125ppm+ ZnSO4 30kg/ha). However, Maximum Gross return (142636.5 INR/ha), Net return (102971.1INR/ha) and B:C ratio (2.59) was recorded with the application of (GA3125ppm+ ZnSO4 30kg/ha). Therefore, it is concluded that the application of (GA3125ppm+ZnSO430kg/ha) was more productive and economically feasible.
