Abstract

Rice (Oryza sativa L.) is one of the major staple foods in the world. The present study was undertaken for the improvement of the yield of scented fine rice variety of aman season through the manipulation of transplanting geometry. The experiment was comprised of two factors; viz. Factors A: Five scented fine rice varieties (Chinigura, Kalijira, Kataribhog, BRRI dhan37 and BRRI dhan38) and Factor B: Three different spacing (20 cm × 20 cm, 25 cm × 15 cm and 20 cm × 10 cm). In case of varieties filled grains per panicle (101) were observed from Chinigura variety, while the maximum grain yield (3.3 t/ha) and straw yield (9.07 t/ha) were found from Kataribhog variety. In case of spacing filled grains per panicle (116.4), non-filled grains per panicle (33.4), the highest 1000 grain weight (17.11 g), grain yield (3.56 t ha-1), straw yield (8.86 t ha-1), harvest index (28.71%) were recorded from  S1(20 cm x 20 cm). In case of interaction the highest number of filled grains per panicle (131.0),the highest grain yield (4.3 t ha-1) and straw yield (10.7 t ha-1) were recorded from the treatment combination of V5S2 (BRRIdhan38+25cmx15cm) while the highest 1000 grain weight(19.07g) was recorded from the combined treatment of (V5S2) (Kalijira + 25 cm x 15 cm).Therefore, the treatment combination of V5S2(BRRI dhan38 + 25 cm x 15 cm) produced the best results for grain yield and straw yield.
