In the research, we aimed to show that the cultivation of a soybean, with its specific soil profile would perform more positively when it was treated with nano-sized di ammonium phosphate (nano DAP) than a proven conventional fertilizer. In the experiment, it is performed in the Agronomy farm of Department of Agronomy at the School of Agricultural Sciences, G. H. Raisoni University at Saikheda, Pandhurna, Madhya Pradesh and implemented during 2024 kharif season.

It was done on the basis of randomized block Design (RBD) and the 8 treatment combinations were to be repeated 3 times each. In T₁-T₇, the RDF concentration of 30, 45 and 60 DAS doses were applied as two liquid concentrations (4 ml L^-1 and 2 ml L^-1) as foliar spray. The set applications were also done in the same stages of development (30, 45 and 60 DAS) on soybean. Provisional data shows that the treatment T₃ (100% RDF + basal + foliar spray nano DAP 4 ml L-1 @ 30, 45 and 60 DAS) have produced summative returns (Rs 85,610), net returns (Rs 41,492) and B:C ratio 1.94. The lowest values were recorded in all the three of them in absolute control, T₈. In addition, T₃ also maintained high nutrient soil status compared with the control untreated.
