Effect of soil and foliar application of nano fertilizers on growth and yield of soybean (Glycine max L. Merrill)

A field experiment was conducted at Research farm, Department of Agronomy, VNMKV, Parbhani during kharif season of 2024-25 to study the effect of soil and foliar application of nano fertilizers on growth and yield of soybean (Glyine max L.). The experiment was laid out in randomized block design with three replication and ten treatments viz. T₁-Control, T₂-RDF (30:60:30:20 NPKS Kg/ha), T₃ -Solid Nano NPK (8:8:12) (@100 Kg/ha) +SSP (189 Kg/ha), T₄- Solid Nano NPK (8:8:12) (@100 Kg/ha) + Foliar spray of Nano DAP at 30 DAS, T₅ -Solid Nano NPK (8:8:12) (@ 50 Kg/ha) + Foliar spray of Nano NPK at 30 DAS, T₆-75% RDF + Foliar sprays of Nano NPK at 30 and 45 DAS, T₇-75% RDF + Foliar sprays of Nano DAP at 30 and 45 DAS, T₈- 50% RDF + Foliar sprays of Nano NPK at 30 and 45 DAS, T₉ -50% RDF + Foliar sprays of Nano DAP at 30 and 45 DAS, T₁₀-Three foliar sprays of Nano NPK at 30,45,60 DAS. The results indicated that the treatment use of 75% RDF + foliar sprays of Nano DAP at 30 and 45 DAS recorded influence on growth parameters such as plant height, number of branches, leaf area, dry matter. While seed yield of soybean was highest with 75% RDF + foliar sprays of Nano DAP at 30 and 45 and was at par with RDF (30:60:30:20 NPKS Kg/ha) and application of Solid Nano NPK (8:8:12) (@100 Kg/ha) + Foliar spray of Nano DAP at 30 DAS.
