Abstract

A field experiment on Effect of Foliar Application on Growth, Yield and Quality of Soybean (Glycine max L.) Under Rainfed Condition was conducted at the Crop Research Centre, School of Agriculture, ITM University Gwalior (M.P.) during the Kharif season of 2022. The experiment was laid out in a randomized block design with 10 treatment combinations, which includes include RDF(100%)@ at the time of sowing, NPK (19:19:19) @ 0.5% at 40 DAS, NPK (19:19:19) @ 1.0% at 40 DAS, NPK (19:19:19) @ 1.5% at 40 DAS, NPK (13:0:45) @ 0.5% at 60 DAS, NPK (13:0:45) @ 1.0% at 60 DAS, NPK (13:0:45) @ 1.5% at 60 DAS, NPK (19:19:19) @ 0.5% at 40 DAS + NPK (13:0:45) @ 0.5% at 60 DAS, NPK (19:19:19) @ 1.5% at 40 DAS + NPK (13:0:45) @1.5 % at 60 DAS and RDF (20:60:20) + Sulphur, and one absolute control, and each treatment was replicated thrice. The result of the experiment revealed that an increase in the foliar fertilizer application had significantly increased the growth and growth analysis of soybeans plant population viz., plant height (cm), No. of leaves per plant, leaf area index, No of branches per plant, dry weight (g plant-1), Days taken in 50 % flowering, AGR, CGR and RGR, Highest recorded with the application NPK (19:19:19) @ 1.5% at 20 DAS + NPK (13:0:45) @1.5% at 40 DAS, being at par with NPK (19:19:19) @ 1.0% at 20 DAS + NPK (13:0:45) @1.0% at 40 DAS, which was closely at par with NPK (13:0:45) @ 1.0% at 40 DAS, and NPK (13:0:45) @ 1.5% at 40 DAS. The lowest was recorded in the control.
