Effect of land configuration and weed management practices on weeds, productivity and profitability of pigeon pea (Cajanus cajan)

Afield experiment was conducted during kharif season of 2020-21 to study the performance of pigeon pea under land configuration and weed management options. The experiment was laid out in split-plot design with 3-land configurations (broad bed and furrow (BBF), ridge and furrow (RF) and flatbed (FB) in main plots and 6-weed management practices in sub plots. Broad bed and furrow planting significantly lower weed biomass and density which consequently resulted in significantly higher growth and yield attributes, seed (1.8 t/ha) and stalk yield (5.19 t/ha) of pigeon pea with the highest net returns ( 65,000/ha) and B:C ratio (2.53) over RF and FB land configuration. Weed management options were superior in reducing weed population and biomass and promoting crop growth and yield over weedy check but all herbicidal options remained statistically at par with each other except 2-hand weeding. Metribuzin @ 0.25 kg a.i./ha PE fb imazethapyr + imazamox (premix) @ 75g a.i./ha at 30 DASfetched the highest net returns of 68000/hawith B:C ratio of 2.74. Thus, pigeon pea grown on BBF with metribuzin 0.25 kg a.i./ha (PE) fb imazethapyr + imazamox @ 75 g a.i./harecorded higher productivity and profitability.
