Effect of Nano Nitrogen and Nano Zinc on Soil Fertility and Crop Productivity of Paddy-paddy Croppin

Field experiments were attended during rabi and kharif seasons of 2020-21 and 2021-22 at Krishi Vigyana Kendra, Gangavathi, Koppal, Karnataka, India, to study the influence of nano nitrogen and nano metallic mineral on soil pregnancy and crop productivity of paddy-paddy cutting system.The experiment was designed in split-split plot design with various levels of nitrogen in main plots, nano nitrogen sprays in substitute-plots and nano zinc sprays in substitute-sub plots which were copied thrice. The results of the study pointed out that application of 125 per insignificant value RDN along with foliar spray of nitrogen @ 4000 ppm and nano Zn @ 2000 ppm has written significantly greater seed yield, straw yield, soil feasible N, P2O5, K2O, S and Zn during two together rabi and kharif season and that was on par with and 100 per insignificant value RDN along with spray of nano nitrogen @ 4000 ppm and nano Zn @ 2000 ppm. Hence for direct management of nano fertilizers in paddy, the request of 100 per insignificant value RDN along with foliar spray of nano N @ 4000 ppm and foliar spray of nano Zn @ 2000 ppm was urged.
