Cotton requires Boron at all growth stages of the crop. The maximum need of Boron is however during the boll development stage. In the Cotton crop, Boron is required for pollination, fertilization, and fiber quality. Boron helps in the assimilation of Nitrogen and Potassium and also for the translocation of carbohydrates from the leaf to the boll. The metabolism of complex carbohydrates & protein and uptake of calcium is due to Boron. This results in a reduction in boll dropping and increased weight. Boron deficiency is more prevalent in non irrigated cotton, thus resulting in poor quality of staple length and weight of the boll. Therefore it is essential to apply Boron in a liquid formulation at the correct stage to improve the staple length and yield of cotton.
