Abstract
A field experiment was conducted during Kharif season 2022 and 2023 at Agronomy research farm, Acharya Narendra Deva University of Agriculture and Technology Kumarganj, Ayodhya, Uttar Pradesh, (India). The experiment was laid out in split plot design with thrice replications. Taking three crop establishment methods Direct Seeded Rice, System of Rice Intensification (SRI) and Transplanted Rice in main plot and seven nitrogen levels control, 100 % RDN through conventional Urea, 100 % RDN through Nano Urea, 80 % RDN through conventional Urea + 20 % RDN through Nano Urea, 60 % RDN through conventional Urea + 40 % through Nano Urea, 40 % RDN through conventional Urea + 60 % through Nano Urea and 20 % RDN through conventional Urea + 80 % through Nano Urea in sub plot. Results showed that significantly higher NPK content, NPK uptake protein content and protein yield was recorded in application of 60 % RDN through conventional Urea + 40 % through Nano Urea which was at par with 40 % RDN through conventional Urea + 60 % RDN through Nano Urea significantly superior over rest of the treatment during both the years of investigations.
