Abstract
The experiment was conducted at Central Cotton Research Farm, Sreepur, Gazipur during cotton growing season of 2009-2011. Cotton variety cv. CB-10 was used under experiment. Eight levels of boron (0.0, 0.25, 0.50, 0.75, 1.0, 1.25, 1.50 and 1.75, g L-1 water) were sprayed at reproductive stage of cotton as treatment. The design of the experiment was randomized completely block design (RCBD) with three replications. Result revealed that, foliar application of boron has significant influence on different traits of cotton. Foliar application of boron may improve the performance of cotton plant by reducing the percentage of boll shattering and increasing the growth of square for better quality fiber.
