    GROWTH AND YIELD OF T. AMAN RICE AS AFFECTED BY VARIETY AND SEEDLING NUMBER
    (Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2011-07) Mahmud, J. A.; Shamsuzzaman, A. M. M.; Haue, M. M.; Islam, M. M.
    A field experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University during July to December 20 I 0 to find out the effect of I, 2 or 3 seedling(s) per hill on growth, yield and yield components of a modern inbred (BRRI dhan49) and four hybrid (BRRI hybrid dhan2, Heera2, Tia and Aloron) transplant Aman rice varieties. The experiment was laid out in randomized complete block design with four replications. Results showed that rice cultivars differed significantly in some characters at different growth stages, such as, tillers number, total dry matter weight, unfilled grain, grain filling percentage and insignificantly in some characters at different growth stage, such as, chlorophyll content, yield etc due to different seedling densities per hill. Numerically the higher grain yield was attributed mainly to the number of effective tillers per hill, filled grains per panicle and 1000-grain weight. Remarkable grain and straw yield were found from the interaction of.BRRI dhan49 planted I seedling and 3 seedlings per hill respectively. Among the hybrid rice varieties, the maximum grain yield was observed from the combination of BRRl hybrid dhan2 with I seedling per hill (V2Sd.
