Online Published on 24 April, 2024. Abstract A field experiment was conducted during Kharif (rainy season), 2021 and 2022 at Agricultural Research station, Chatabar, Faculty of Agricultural Sciences, SOADU, Bhubaneswar. The soil of the experimental field was sandy loam in texture. The experiment comprising of seven treatments viz. pendimethalin 30 EC at 1000 g /ha, oxadiargyl 80WP at 100 g/ ha, pendimethalin PE fb bispyribac-sodium (1000 + 25 g/ha), oxadiargyl 80 WP PE fb bispyribac-sodium (100+ 25 g/ ha), bispyribac-sodium 25 g/ha, weedy check and weed free were laid out in a randomized block design with three replications. Results revealed that oxadiargyl at 100 g/ha fb bispyribac-sodium 25 g/ha recorded the lowest values of total weed density and weed dry weight at 45 DAS during both the years and was at par with combination of pendimethalin PE followed by bispyribac-sodium (1000+25 g/ha) PoE. The highest grain yield of direct-seeded rice along with higher yield attributing characters like number of filled grains/panicle, panicle/m2 and test weight were recorded under weed free treatment and it was at par with oxadiargyl at 100 g/ha fb bispyribac-sodium 25 g/ha.
