ABSTRACT

Field experiment was conducted during the kharif season 2016 to evaluate the effect of Variety and Spacing on the Productivity of Direct Seeded Rice (Oryza sativa L.). Four rice cultivars CAU-R1, RCM-7, RCM-10 and KD-263 were sown with three row spacing 15, 20 and 25 cm). The experiment was laid out in a (FRBD) with three replication. Consequences shown that among four rice varieties, CAU-R1 produced significantly higher no of tiller per square meter (96.44) and no of effective tiller per square meter (88.58) than other varieties. Significantly higher no of filled grain per panicle (146.18), test weight (26.71g), grain yield (50.57 q /ha) and straw yield (66.60 q ha-1) were also recorded from CAU-R1 than other verities. Planting at 25 cm row spacing resulted in significantly higher number of tillers per square meter (90.18), effective tillers per square meter (86.82), Panicle length (25.24 cm), No. of filled grain/ panicle(146.27) and grain yield (44.68 q ha-1) as compared to 20 and 15cm row spacing. However, plant height (130.09 cm), No. of unfilled spiklets per panicle (36.12) and Straw yield (66.70 q/ha) were significantly greater with 15 cm row spacing.
