Soil Fertility Responses to Different Nitrogen Application Approaches Involving Prilled Urea and Foliar Nano-urea in Wheat

Gayatri P. Turkar, H. K. Rai, A. K. Upadhyay, R. K. Sahu, S. K. Singh & Umesh Singh · Journal of Experimental Agriculture International · 2026

Wheat productivity depends strongly on adequate nitrogen nutrition; however, conventional prilled urea is often associated with low nitrogen-use efficiency and substantial nutrient losses. Foliar nano-urea has emerged as a potential complementary nitrogen source that may improve...

Effect of Zinc Application Strategies on Growth, Productivity, Zinc Uptake by Rice and Residual Soil Zinc Status under Rice-Wheat Cropping System of Central India

A. K. Upadhyay, H. K. Rai, Prinsu Singh & S. K. Behera · Journal of Experimental Agriculture International · 2026

The rice-wheat cropping system in India, particularly in Madhya Pradesh, faces widespread zinc deficiency, which limits yield and grain quality. Foliar zinc application, nano-fertilizers, and zinc solubilizing bacteria (ZSB) have proven effective in enhancing crop growth, zinc up...
