Abstract
In the rabi season of 2021-22, the investigation was conducted at Bihar Agricultural University Sabour, Bhagalpur (Bihar), to study the effects of nano urea on growth attributes, yield and nitrogen use efficiency of irrigated wheat (Triticum aestivum L.). Randomized block design (RBD) with thirteen treatments in three replications was used. Treatments involved different levels of nitrogen i.e- 0, 50, 75 and 100% of recommended dose of nitrogen (RDN) along with 5% urea solution and nano-urea applied at tillering and jointing stages. The results showed that 100% and 75% RDN with two sprays of nano urea significantly improved the yield attributes like plant height, Leaf area Index (LAI), test weight, dry matter accumulation and yield. This study gave the highest grain yield of 4573 kg h-1 for RDN + two spray of urea (5%) and 4492 kg h-1 from RDN + two spray of nano urea. The present study has also shown that application of 75% RDN with nano urea resulted in the highest NUE of 10.20 kg kg-1. This means that nano-urea can be used with conventional urea without an adverse effect on high productivity of wheat.
