Abstract:
An investigation in the field named "Effect of Herbicides and their Combination on Economics of Onion Cultivation (Allium cepa L.)" was conducted in 2020–2021 and 2021–2022 at the Horticultural Research and Instructional Farm, Indira Gandhi Agriculture University, Raipur (C.G.). Ten treatments were reproduced three times, and the experiment was set up using a randomized block design. Hand weeding and five herbicide combinations of Oxyfluorefen, Oxdiargyl, Pendimethalin, Fluazifop-p-butyl, and Quizalofop-p-ethyl were evaluated in comparison to a weedy control (untreated) plot. The herbicide treatment (T₇), consisted of Oxyfluorfen 23.5% at 0.25 kg a.i./ha, Quizalofop-p-ethyl 5% EC at 75 g a.i./ha, Pendimethalin 30% EC at 1 kg a.i./ha, and manual weeding 40 days after transplanting, were considerably superior to other treatments. The results showed that treatment T₇ produced the highest income (gross and net) and b:c ratio.
