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.
