Abstract:
The study entitled, “Effect of nitrogen & phosphorus nano-fertilizers on growth and yield of maize (Zea mays L.)” was undertaken by conducting a laboratory experiment of synthesis and characterization of nitrogen and phosphorus nano-fertilizer and a field experiment at Regional Research Station, Anand Agricultural University, Anand (Gujarat) during summer and kharif seasons of the year 2021. The field experiment was laid out in Randomized Block Design comprising fourteen treatments of T1[Control(No NPK)], T2[100% RDF (150 N-60 P-0 K kg ha-1)], T3[75% RDF + Nano N & P through foliar application (1000 ppm)], T4[75% RDF + Nano N & P through foliar application (2000 ppm)], T5[75% RDF + Nano N & P through foliar application (3000 ppm)], T6[50% RDF + Nano N & P through foliar application (1000 ppm)], T7[50% RDF + Nano N & P through foliar application (2000 ppm)], T8[50% RDF + Nano N & P through foliar application (3000 ppm)], T9[25% RDF + Nano N & P through foliar application (1000 ppm)] and T10[25% RDF + Nano N & P through foliar application (2000 ppm)], T11[25% RDF + Nano N & P through foliar application (3000 ppm)], T12[ Seed treatment Nano N & P + Nano N & P through foliar application (1000 ppm)], T13 [Seed treatment Nano N & P + Nano N & P through foliar application (2000 ppm)], T14[ Seed treatment Nano N & P + Nano N & P through foliar application (3000 ppm)]. The instrumental analysis results indicated that synthesized nitrogen and phosphorus nano-fertilizer were of 229.9 nm particle size with Poly-dispersity Index of 0.426, mono dispersed, pure, stable and showed characteristic absorption H-O bond at wave number of 3431.27 cm-1. Significantly higher plant height, cob length, grain yield and straw yield was achieved under application of T4- 75% RDF + Nano N & P through foliar application (2000 ppm) during the summer, kharif and pooled analysis.
