Effect of integrated weed management on growth and yield of direct seeded dibbled rice (Oryza sativa L.)

A field experiment was conducted during kharif 2023 at Instructional Farm, Department of Agronomy, College of Agriculture, Dapoli (MS) to evaluate integrated weed management in direct seeded dibbled rice. The experiment was conducted in randomized block design with ten treatments which was replicated thrice. Results of the experiment showed that growth attributes viz, (plant height, number of functional leaves hill-1, number of tillers hill-1, dry matter accumulation hill-1) and yield of rice found maximum in treatment T9 i.e., Weed Free Check (1 HH at 20 DAS and 2HW at 40 and 60 DAS) over the rest of treatments. Whereas, treatment Oxyfluorfen 23.5% EC @ 0.3 kg a.i. ha-1 (PE) fb Bispyribac sodium (Fujisuper 10% SC) @ 25 g ha-1 (PoE) at 30 DAS (T3), Oxyfluorfen 23.5% EC @ 0.3 kg a.i. ha-1(PE) fb 1 HW at 30 DAS (T1) and Pendimethalin 38.7% CS @ 1.0 kg a.i. ha-1 (PE) fb Bispyribac sodium (Fujisuper 10% SC) @ 25 g ha-1 (PoE) at 30 DAS (T4) were statistically at par to the treatment T9. Least weed index was found in treatment T3 i.e., Oxyfluorfen 23.5% EC @ 0.3 kg a.i. ha-1 (PE) fb Bispyribac sodium (Fujisuper 10% SC) @ 25 g ha-1 (PoE) at 30 DAS. Weed control efficiency found maximum in treatment T9 i.e., Weed Free Check (1 HH at 20 DAS and 2HW at 40 and 60 DAS).
