A Study on the Standardization of Nanonitrogen and Nanozinc for Sustainable Paddy Production

Abstract

Investigation on Standardization of nano nitrogen and nano zinc for sustainable paddy production was undertaken. The growth, yield, quality and economics were considerably greater withapplication of 75% N and two foliar sprays of nano nitrogen and nano zinc at 25 to 30 and 45 to 50 DAT. The same treatment was statistically better in boosting the grain and straw production (6167 and 7288 kg ha^-1), net returns (Rs. 60,899 ha^-1) and B:C ratio (1.96). It was followed by treatment of 75% N and two foliar sprays of nano nitrogen at 25 to 30 and 45 to 50 DAT. The results revealed that application of 75% N and two foliar sprays of nano nitrogen and nano zinc at 25 to 30 and 45 to 50 DAT under SRI method was significantly higher in grain and straw yield, quality and economics whereas, SRI with recommended practice recorded significantly higher microbial population and soil enzymatic activity at 30 DAT and at 50% flowering.
