Abstract
The present study aimed to evaluate Crop Establishment Methods and Nano Urea Versus Conventional Urea on Growth Indices in Rice Crop (Oryza sativa L.). Method of crop establishment influences the performance of rice through its effect on growth and development. Although, system of rice intensification has been reported to be the best establishment method. In traditional fertilizers, there is a huge loss of fertilizers by various manners like drift, leaching, runoff, microbial degradation, hydrolysis and photolysis. Bio accessibility of nutrients to plant is much lower relative to the rate of conventional fertilizers applied. The experiment was conducted during two consecutive seasons of Kharif 2022 and 2023 at the Agronomy Research Farm, Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya (U.P.), India. The nitrogen level had significantly affected on crop growth rate, relative growth rate and net assimilation rate at all the stages of crop growth during both the years of investigations. The maximum Net assimilation rate at 30-60 and 60-90 DAS/DAT and crop growth rate, relative growth rate at 30-60, 60-90 and 90 to harvest DAS/DAT was recorded under 60% RDN through conventional Urea + 40% RDN through Nano Urea which was at par with 40% RDN through conventional Urea + 60% RDN through Nano Urea treatment, while significant over rest of the treatment during both the years of investigations.
