ABSTRACT:
To find out the effect of planting methods on the yield and yield
attributes of short duration Aman rice
varieties, a field trial was conducted at the
farm of Bangladesh Rice Research Institute, Gazipur, during July to November
2012. The treatments comprised of three BRRI released high yielding varieties viz.,
BRRI dhan39, BRRI dhan49 and BRRI dhan57 and three planting methods viz., direct seeding of dry seed, direct seeding of sprouted seed and
transplanting. It was a factorial experiment conducted in a Randomized Complete
Block Design with three replications. Planting methods had a significant effect on the growth duration of rice. The rice crop
established with direct seeding of the dry and
sprouted seed matured 7 days earlier than transplanting. The variety BRRI
dhan39 gave the highest yield (4.964 t·ha-1) when grown with direct
seeding of sprouted seed compared to other
varieties. The highest net return (23362.00 BDT ha-1) and cost
benefit ratio (1:1.49) were observed in direct seeding of the sprouted seed method. So, direct
seeding of sprouted seed might be the best planting method because about 19.94% production cost is
reduced due to the omission of seedling raising and transplanting operations as
well as the reduction in the length of the crop cultivation period.
