- Intervention effect Hand weeding at 25 and 50 DAS reduced weed dry weight to 11.04 g m-².
- Intervention effect Hand weeding significantly improved weed control efficiency.
- Intervention effect Hand weeding yielded the highest grain yield of 40.19 q ha-1.
- Intervention effect Hand weeding yielded the highest straw yield of 54.51 q ha-1.
- Intervention effect Sequential pendimethalin and bispyribac application was statistically comparable to hand weeding.
- Intervention effect Pretilachlor followed by bispyribac had similar performance.
- Intervention effect Sole bispyribac application had similar performance.
- Observation Weedy check performed lowest across evaluated parameters.
- Recommendation The authors recommend pendimethalin followed by bispyribac as an effective, economically viable weed control option.
