Abstract:
This study investigated the essential characteristics of nano DAP (Diammonium Phosphate) designed for seed treatment and foliar spray applications. The Indian Farmers Fertilizer cooperative limited nano DAP (Diammonium Phosphate) sample was sent to Deprtment of SAIF-DST centre, shivaji university, Kolhapur for analysis of particle size, PDI, KCPS and zeta potential. The particle size analysis revealed an average size of 293.9 nm, indicating the formation of nanoparticles approximately three times more than particle size of nano DAP (Diammonium Phosphate) by IFFCO (Indian Farmers Fertilizer cooperative limited) findings. The Poly-dispersity Index (PdI) scale, ranging at 0.860, suggested that the particles becomes too polydispersed across all samples, positioning them above the range value. The Count rate of IFFCO (Indian Farmers Fertilizer cooperative limited) nano DAP was 3.5 which was below the range of normal count rate, which indicated that less number of nanoparticle detected by instrument. Furthermore, zeta potential value of (-12.1 mV), signifying a negative charge on the nano DAP (Diammonium Phosphate) particles in aqueous suspension. This negative zeta potential contributed to enhanced stability, highlighting the potential for improved longevity and efficacy in agriculture. The findings collectively suggested that the developed nano DAP formulation held promise as a stable and less effective solution for seed treatment, offering lacks of benefits in crop yield and overall agricultural productivity.
