Effect of integrated weed management on growth, yield and yield of rabi mustard (Brassica junicea. L) under sandy loam soil of Telangana

A field experiment was conducted at Agriculture Research Station, Karimnagar during Rabi, 2023-24 to evaluate the effects of integrated weed management practices on growth and yield of mustard. The experiment was laid out in randomized block design with three replications and ten treatments viz., T₁ -Pendimethalin 30% EC @ 1.0 kg a.i/ha PE, T₂ -Oxyfluorfen 23.5% EC @ 0.1 kg a.i/ha PE, T₃ -Pendimethalin 30% EC @ 1.0 kg a.i/ha PE fb Propaquizafop 10% EC @ 0.0625 kg a.i/ha PoE, T₄ - Oxyfluorfen 23.5% EC @ 0.1 kg a.i ha^-1 PE fb Propaquizafop 10% EC @ 0.0625 kg a.i/ha PoE, T₅ -Pendimethalin 30% EC @ 1.0 kg a.i./ha PE fb Power weeding at 30DAS, T₆ -Oxyfluorfen 23.5% EC @ 0.1 kg a.i./ha PE fb Power weeding at 30DAS, T₇ -Pendimethalin 30% EC @ 1.0 kg a.i./ha PE fb Paddy straw mulch @ 5 t/ha at 20 DAS, T₈ -Oxyfluorfen 23.5% EC @ 0.1 kg a.i./ha PE fb Paddy straw mulch @ 5 t/ha at 20 DAS, T₉ -Weed free (HW at 20 and 40 DAS), T₁₀ -Weedy check. Based on the experimental results, it can be concluded that among various integrated weed control tactics, application of Oxyfluorfen 23.5% EC @ 0.1 kg a.i./haPE fb Power weeding at 30DAS and Oxyfluorfen 23.5% EC @ 0.1 kg a.i./ha PE fb Paddy straw mulch @ 5 t/ha at 20 DAS proved to be the most effective treatment in controlling weeds. This regime showed superior performance in growth, yield attributes and overall yield due to the high weed control efficiency and lower weed index.
