Abstract:
An experiment was conducted to assess the effect of tillage and weed management practices on nutrient uptake and economics of onion cv. Agrifound Light Red at Dr. YSRHU- College of Horticulture Anantharajupeta, Annamayya Dist, Andhra Pradesh during rabi season of 2022-23. The experiment was laid out in split plot design with two main plots and eight subplots, replicated thrice. The results indicated that deep tillage led to significantly higher values of NPK uptake and economics of onion. Among the weed management practices, mulched plot recorded higher values of NPK uptake, net returns and B:C ratio followed by Stale seed bed + Pendimethalin 30% EC (PE) @ 3.5 lit/ha + Combined application of Oxyfluorfen 23.5% EC @ 0.25 kg a.i./ha and Quizalofop ethyl 5% @ 0.05 kg a.i./ha at 20 and 40 DAT.
