IMPACT OF SCHEDULING PRILLED AND NANO-UREA ON GROWTH AND YIELD OF WHEAT (Triticum aestivum L.)
Year: 2026
Type: article
Abstract: A field experiment was conducted during Rabi 2024-25 at Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur to evaluate the effect of scheduling prilled urea and nano-urea on growth and productivity of wheat grown in a Vertisol. The experiment comprised nine treatments including control, varying levels of recommended nitrogen dose (RDN) and foliar application of nano-urea at different growth stages, laid out in a randomized block design with three replications. Results revealed that application of 100% recommended dose of fertilizer (RDF) produced significantly superior growth attributes and yield components compared with the control. The maximum grain yield (4.97 t ha-1 ) and straw yield (7.06 t ha1 ) were recorded under 100% RDF, representing an increase of 49.7% and 30.3% respectively, over control. However, these yields were statistically comparable with treatments receiving 50% RDN supplemented with nano-urea foliar sprays, indicating the potential of nano-urea to partially substitute conventional nitrogen fertilizer without compromising productivity. Correlation analysis showed strong positive associations among growth and yield parameters, with grain yield exhibiting significant (p < 0.01) relationship with plant height, tiller number, chlorophyll index and grains per earhead. The findings suggest that nano-urea can partially substitute conventional nitrogen fertilizer without compromising wheat productivity under Vertisol conditions
