Title : Effect of Weed Management Practices on Weed Dynamics and Productivity of Sweet Corn (Zea mays L. Ssp saccharata) under Organic Production System

Abstract :

A field experiment was conducted during 2019-20 at the Agronomy Farm, Rajasthan College of Agriculture, Udaipur. The experiment was laid out in a RBD with three replications and twelve treatments viz. T1: Hoeings at 20 and 40 DAS, T2: Power weeding at 20 DAS + hoeing at 40 DAS, T3: Stale seedbed + two hoeings at 20 and 40 DAS, T4: Stale seedbed + power weeding at 20 DAS + hoeing at 40 DAS, T5: Stale seedbed + hoeing at 20 DAS + straw mulch at 30 DAS, T6: Stale seedbed + plastic mulch at sowing, T7: Soil solarization + two hoeings at 20 and 40 DAS, T8: Soil solarization + power weeding at 20 DAS + hoeing at 40 DAS, T9: Soil solarization + hoeing at 20 DAS + straw mulch at 30 DAS, T10: Soil solarization + plastic mulch at sowing, T11: Weed free check and T12: Weedy check. On the basis of experiment result it was revealed that T10 and T6 at all stages of observation and T9 and T5 at 30 DAS and T11 up to 50 DAS were the most effective treatment in reducing weed density and weed dry matter accumulation as compared to other treatments. Like weed dry matter accumulation T10 and T6 gave 100 per cent weed control efficiency at all stages of observation. The highest green cob and fodder yield were recorded in T10 (12.97 and 26.32 tonnes ha-1) which was statistically at par with T9 (12.77 and 24.57 tonnes ha-1, respectively).
