Productivity and nitrogen use efficiency of wheat Triticum aestivum as influenced by foliar supplementation of nitrogenous fertilizer

Abstract

A field experiment entitled Productivity and Nitrogen use efficiency of wheat (Triticum aestivum) as influenced by foliar supplementation of nitrogenous fertilizer was conducted during rabi season of two consecutive years 2022-23 and 2023- 24, at the research farm, Bihar Agricultural College, Sabour, Bhagalpur to study the effect of soil and foliar supplementation of nitrogenous fertilizer on the performance of wheat. The experiment laid out adopting a Split Plot Design with 3 main plots and 5 sub plots treatments replicating thrice with wheat (DBW187) viz, M1-100 % recommended dose of nitrogen (RDN), M2- 75 % RDN, M3- 50 % RDN, and five different sub plots viz. S1-One spray of nano urea at tillering stage, S2-Two spray of nano urea at tillering and jointing stage, S3-Two spray of urea (5 %) at tillering and jointing stage, S4-One spray of NPK 19:19:19 (1 %) at tillering stage and S5-No Spraying (Control). newline
