Foliar application of plant nutrients appeared to be the most promising tool in modern plant nutrition management. While foliar application provides a quick relief to the plants under the deficiencies of various nutrients, it also helps maintain/improve growth, yield and quality of crops under nutrient deficiency stresses. This monograph emphasizes the role of foliar application of nitrogen as urea in enhancing the nutrient uptake (nitrogen, phosphorus and potassium), yield and quality of wheat.

Potassium (K) nutrition ensures optimum yield and quality of crops. This monograph evaluates the impacts of varying levels of K on the growth, yield and K accumulation of two sunflower hybrids, viz. Hyson-33 and Hyson-39, grown at five different rates of K, i.e. 0 (control), 30 through 120 kg/ha. Across genotypes, K nutrition significantly enhanced biomass yield, number of leaves, stem diameter, head diameter, head length, head weight, achene yield and K accumulation at 120 kg K/ha, as against control. Across K nutrition, Hyson-39 had more biomass yield, number of leaves, stem diameter, head...
