Productivity of Field Crops as Influenced by Foliar Spray of Nutrients: A Review

Foliar application of nutrients plays an important role in changing growth and physiological characteristics of field crops. In optimizing fertilization strategies, inclusion of foliar application improves fertilizer use efficiency and reduces environmental pollution. Foliar application of nutrients during flower and grain formation stages has been shown to be effective in efficient utilization of nutrients by crops and thereby reduce flower shedding and increase the yield. Keeping this in view, the literatures on foliar application of Di-ammonium phosphate and boron on the growth, yield and quality of field crops are reviewed in this paper.
