Abstract:
A field experiment was conducted at Agriculture Research farm, Rama University, Kanpur during rabi seasons of 2021-22 to study the effect of Integrated weed management on growth and yield of Indian mustard (Brassica juncea L.) The experiment was laid out in randomized block design with three replications and 9 treatments. The treatments considered of T₁: Control, T₂: Straw mulch, T₃: Polyethelene Mulch, T4: One hand weeding (40 DAS), T₅: Two hand weeding (30 and 45 DAS), T₆: Three hand weeding (30 DAS, 45 DAS and 60 DAS), T₇: Pendimethalin @ 1.5 kg/ha (pre-emergence) + One hand weeding (40 DAS), T₈: Pendimethalin @ 1.0 kg/ha (pre-emergence) + Two hand weeding (30&45 DAS and T₉: Pendimethalin @ 0.5 kg/ha (pre-emergence) + Isoproturon @ 1.0 kg/ha (45 DAS). Among the weed management treatments, the growth and yield parameters of Indian mustard viz. plant height, number of primary and secondary branches per plant, dry matter weight per plant, leaf area, number of siliqua per plant, number of seeds per siliqua, 1000 seed weight, seed weight per plant, seed yield and stover yield per hectare, biological yield, Oil content, protein content were recorded highest with treatment T6 - Three hand weeding (30 DAS, 45 DAS and 60 DAS), followed by T₉, T_3, T_2, T_7, T₅, T₈ and T₄.
