Abstract
The experiment was conducted at the Bangladesh Rice Research Institute Farm, Gazipur, in Boro season. BasmatiPNR, Basmati370, Basmati375 and Basmati-D were transplanted started from 10 December, and continued up to 25 January in the following year, at an interval of 15 days. Forty day old seedlings were transplanted spaced at 20 cm × 15 cm, to find out the optimum planting time and to select the Basmati varieties having high yield potential. The tallness of plants, number of tillers and dry matter were increased with the advancement of planting dates. On the country, number of panicles, grains panicle-1, panicle length, grain yield and growth duration decreased as delayed planting dates. The short stature BasmatiPNR and tall plant of Basmati375 exhibited higher number of panicles, grains panicle-1 and heavier individual grain which contributed to increase grain yield. Thus, high yield potential varieties BasmatiPNR and Basmati375 to be planted in optimum time on 10 December, to obtain maximum grain yield of rice in Boro season.
