Effect of weed management on growth and yield of Rabi onion

A trial entitled “Effect of weed management on growth and yield of rabi onion” was carried out in the Weed Control Research Farm, Junagadh Agricultural University, Junagadh, on medium black calcareous soil during the rabi season of 2021–2022. The 14-treatments experiment was set up in a randomized block design with three replications. The findings showed that next to weed free treatment, tank-mix pendimethalin 450 g ha^-1 + oxyfluorfen 120 g ha^-1 as pre-planting fb HW at 40 DATP (T₃), tank-mix pendimethalin 450 g ha^-1 + oxyfluorfen 120 g ha^-1 as pre-planting fb pre-mix propaquizafop + oxyfluorfen 43.75+105 g ha^-1 at 40 DATP (T₁₀) and tank-mix pendimethalin 450 g ha^-1 + oxyfluorfen 120 g/ha as pre-planting fb pre-mix quizalofop + oxyfluorfen 100 g ha^-1 at 40 DATP (T₉) enhanced growth characteristics, such as the number of leaves per plant and neck thickness; yield characteristics, such as bulb weight, equatorial diameter, and polar diameter; and finally produced better bulb and stover yields. Also gave significantly higher gross and net returns as well as BCR.
