Effect of different transplanting methods on yield of Binadhan-14 (Oryza sativa L.) at late boro season under climate change

Abstract

To find out the suitable planting method under climate change on the yield and yield attributes of late boro rice in Bangladesh, an experiment was conducted at Bangladesh Institute of Nuclear Agriculture (BINA) farms at boro season of 2014-15. Three different sowing methods viz., direct seeding with sprouting seed & without sprouting seed and transplanting were practised to evaluate Binadhan-14 along with one check BRRI dhan 28. Due to climate change, water level goes downwards, government wants to replace boro areas as late boro to minimize irrigation water and keep the water level constant. In this study, Binadhan-14 showed higher grain yield than BRRI dhan 28. Comparative effect of transplanting method, the highest grain yield was produced in transplanting method. Direct seeding was seven days earlier than transplanted rice. However, considering crop duration direct seeding with sprouting seed will be effective by sacrificing grain yield.
