ABSTRACT

Appropriate agronomic practice like plant density has a profound effect on the plant growth, development and yield of cotton. Hybrid cotton has gaining popularity among the Bangladeshi farmers over the last couple of years who used to grow it in wider plant spacing of 90x45 cm. Field experiments were conducted to assess the performance of Rupali-2 under different plant spacing (10, 20, 30 and 45 cm) in Randomized Complete Block Design at Cotton Research Center, Sreepur, Gazipur, Bangladesh. The experiment revealed that plant spacing has significant effect on the number of sympodial branches plant^-1, number of bolls plant^-1 and seed cotton yield. The highest seed cotton yield (4.00 t ha^-1) was obtained from 90 × 10 cm plant spacing.
