An experiment was conducted to study the efficacy of post-emergence herbicides in direct seeded rice at I.G.K.V, Raipur, Chhattisgarh during Kharif2017 and 2018, having eleven treatments replicated thrice in randomized block design. The data revealed that the total dry matter of grasses were 79.4 and 78.4% higher during 2018 as compare to 2017 at 30 and 60 days after sowing, respectively. However, the total dry matter of broad leaved weeds were 44.9 and 77.4% higher during 2017 as compare to 2018at 30 and 60 days after sowing, respectively. The weed free (20 & 40 DAS) (T10) treatment and weedy check (T11) treatment recorded the highest and lowest value with respect to crop dry matter accumulation, weed control index, number of filled grains per panicle, grain and straw yield, respectively. Among the herbicide treatments, the highest yield attributes, grain and straw yield was found under the application of bispyribac sodium 2% + 2,4- D sodium salt 54.3% SP with adjuvant (30.0 + 814.5 g ha-1) (T6), which was at par with the weed free (20 & 40 DAS) (T10) treatment.

Keywords: Direct seeded rice, Post–emergence herbicides, Number of filled grains per panicle and Weed control index
