Abstract:
A field experiment entitled “Effect of basal and foliar application of N, P, and K on growth and yield, of soybean(Glycine max L.).” 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, RDF + DAP @ 2% at 30 DAS and DAP @ 2% at 50 DAS, RDF + UREA @ 2% at 30 DAS and @ 2% UREA at 50 DAS, RDF + KNO₃ @ 2% at 30 DAS and KNO₃ @ 2% at 50 DAS, RDF + MOP @ 2% at 30 DAS and MOP @ 2% at 50 DAS, RDF + DAP @ 2% + UREA @ 2% at 30 DAS and DAP @ 2% + UREA @ 2% at 50 DAS, RDF + DAP @ 2% + KNO₃ @ 2% at 30 DAS and DAP @ 2% + KNO₃ @ 2% at 50 DAS, RDF + DAP @ 2% + MOP @ 2% at 30 DAS and DAP @ 2% + MOP @ 2% at 50 DAS, RDF + UREA @ 2% + MOP @ 2% + KNO₃ @ 2% at 30 DAS and UREA @ 2% + MOP @ 2% + KNO₃ at 50 DAS, and one absolute control, and each treatment was replicated thrice. The result of the experiment revealed that an increase in the basal and foliar fertilizer application had significantly increased the growth of soybeans viz., plant height (cm), No. of leaves per plant, leaf area index, and dry weight (g plant^-1), yield attributes viz., Number of seed pods, Number of pods plant^-1 seed yield (kg ha^-1), stover yield (kg ha^-1), and Harvest index, gross returns, net returns, and B-C ratio, the Application of RDF + DAP @ 2% + UREA @ 2% at 30 DAS and DAP @ 2% + UREA @ 2% at 50 DAS which was significantly superior over rest of the treatment. However, it was at par with the RDF (100%) + UREA @ 2% + MOP @ 2% + KNO₃ @ 2% at 30 DAS and UREA @ 2% + MOP @ 2% + KNO₃. The lowest grain yield was recorded in the control.
