EFFECT OF VARIETY AND PLANTING METHOD ON THE GROWTH AND YIELD OF AUS RICE

Abstract

An experiment was conducted at the Agronomy farm of Sher-e-Bangla Agricultural University, Dhaka in order to investigate the effect of variety and planting method on the growth and yield of aus rice. Four varieties [(i) BRRI dhan65, (ii) BRRI dhan55, (iii) BRRI dhan48 and (iv) BRRI dhan43] and three planting methods [(i) M 1 (Broadcasting), (ii) M 2 (Dibbling) and (iii) M 3 (Transplanting)] were considered. The experiment was set up in Randomized Complete Block Design with three replications. There were 12 treatment combinations. Considerable effect was observed on growth, yield attributes and yield of aus rice affected by different varieties,planting methods and their combinations. Both variety and planting methods and also with their combination had significant effect on plant height, root length, number of tillers per hill, number of leaves per hill, panicle length, number of grain per panicle, 1000 seeds weight, grain yield, straw yield, biological yield and harvest index of the crop. The highest number of effective tillers hill (17.00), panicle length (22.42 cm), total number of grains panicle ii

-1 (120.80), number of filled grains panicle -1 (110.10), 1000 seed weight (24.58 g), seed yield (4.63 t ha ), straw yield (6.30 t ha -1 ), biological yield (10.90 t ha -1 ) and harvest index (42.36%) were obtained from V 3 M 3 combination of treatments but V 4 M 1 showed the lowest result on the parameters mentioned.
