Tiller Production and Yield Improvement of T. Aman Rice Varieties Through Wider Spacing (original) (raw)
Abstract: Performance of three T. aman rice variety namely, Biroyn (Indigenous) (V1), BINA dhan7 (V2) and BRRI dhan34 (V3) were evaluated with three levels of plant population density viz. raised bed with plant spacing of 75 cm x 75 cm (S1), leveled bed with plant spacing of 50 cm x 50 cm (S2) and leveled bed with plant spacing of 25 cm x 15 cm (S3). Variety exerted significant influence on yield of transplant aman rice. The highest grain yield (7.1 t ha 1) and straw yield (11.7 t ha 1) was observed in Biroyn indigenous variety. The plant spacing of 50 cm x 50 cm showed the highest (6.8 t ha 1) grain yield and straw yield (9.6 t ha 1) among the plant population treatments. It was observed that in most of the cases, all the varieties performed better for their yield contributing characters with wider spacing of 50 cm x 50 cm. With attention to results of this experiment due to higher (9.2 t ha 1) grain yield in V S treatment this level suggest for planting the indigenous Biroyn variety 1 2 with 50 cm x 50 cm spacing in transplant aman season. Besides this, genotype presumes a promising one deserves extensive research onwards.
