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

straw yield (6.30 t ha
