Foliar Nutrition in Cotton - A Review

Nutrients play a major role in influencing the growth and development in cotton. Generally major nutrients viz., N, P and K are supplied to cotton either through soil or foliage and the micronutrients and growth promoting substances applied as foliar feeding. But, foliar application of nutrients through fertilizers such as Di ammonium phosphate (DAP), Potassium chloride (KCl) and micronutrient mixtures during flower and boll development stages have been shown to be effective in efficient utilization of nutrients by cotton and thereby reduce boll shedding and increase the yield. In this context, the literatures on foliar nutrition of major and micronutrients on the growth, yield and quality of cotton are reviewed in this paper.
