Impact of Nano-Urea Application on Wheat Yield and Soil Properties: A Sustainable Approach to Nutrient Management

Abstract

A field experiment was conducted during the winter (rabi) season of 2022–23 at Dugurpur village Nuaon Block under On Farm Trial by Krishi Vigyan Kendra, Kaimur, to investigate the Impact of Nano-Urea Application on Wheat Yield and Soil Properties. The experiment was tested in a randomized block design with 2-nano-urea based treatment,viz. farmers practice  (100% RDF), 50% of RDN & 100% PK + nano urea @4ml/lt. water (Single spray at 35 DAS), 50% of RDN & 100% PK + 2 sprays of Nano Urea at (35 DAS) and (60-65DAS) @ 4 ml/lt water. Results revealed that, yield attributes were significantly higher with 50% RDN& 100% PK along with nano urea. This treatment also resulted in 1.6 and 4.2% more grain yield with 100% RDF (33.14 q/ha).The effective tillers/m2 and number of grains/spike whichresulted in significantly higher grain yield. Thus, 50% RDN  & 100% PK along with 50% of RDN & 100% PK + 2 sprays of Nano Urea at (35 DAS) and (60-65DAS) @ 4 ml/lt water are the more productive options for wheat-growingfarmers keeping view of the uprising cost and crisis of urea.
