Abstract:
The experiment was conducted at College of Agriculture and Research Station, Janjgir-Champa, IGKV, Raipur (C.G.) during rabi season 2016-17 and 2017-18 to find out the effect of integrated weed management practices on growth yield and economic return in onion (Allium cepa L.). The 14 treatments comprised of pendimethalin @ 1.5 kg ha-1 as PE, pendimethalin @ 1.5 kg ha-1 as PE fb one hand weeding at 45 DAT, pendimethalin @ 1.5 kg ha-1 as PE fb fenoxaprop-p-ethyl 0.080 kg ha-1 as PoE at 45 DAT, oxyfluorfen @ 0.25 kg ha-1 as PE, oxyfluorfen @ 0.25 kg ha-1 as PE fb one hand weeding at 45 DAT, oxyfluorfen @ 0.25 kg ha-1 as PE fb fenoxaprop-p-ethyl 0.080 g ha-1 as PoE at 45 DAT, oxadiargyl @ 0.080 kg ha-1 as PE, oxadiargyl @ 0.080 kg ha-1 as PE fb one hand weeding at 45 DAT, oxadiargyl @ 0.080 kg ha-1 as PE fb fenoxaprop-p-ethyl 0.080 kg ha-1 as PoE at 45 DAT, propaquizofop 5% + oxyfluorfen 12% @ 0.15 kg ha-1 PE , pendimethalin @ 1.0 kg ha-1 PE fb propaquizofop 0.05 kg ha-1 PoE at 45 DAT, oxadiargyl @ 0.070 kg ha-1 PE fb propaquizofop 0.05 kg ha-1 PoE at 45 DAT, Two hand weeding at 20 and 50 DAT and weedy check. The experiment was laid out in randomized block design with three replications. Onion variety “Agrifound Light Red” was grown as a test crop.

The experiment was laid out in randomized block design with three replications. Onion variety “Agrifound Light Red” was grown as a test crop.
In the experimental field weeds, such as Parthenium hysterophorus, Physalis minima, Chenopodium album, Cyperus rotundus, Cynodon dactylon, Melilotus indica and Medicago denticulata were the predominant weeds. At initial period of crop growth, broad leaf weeds contributed more as compared to grasses and sedges. The weed density and biomass of weeds were found minimum under two hand weeding at 20 and 50 DAT. Whereas, weed control efficiency was found maximum under two hand weeding at 20 and 50 DAT. All the herbicides treatments improved crop growth viz. plant height, Number of leaves, dry weight of leaves, fresh weight of bulb, economics and reduced weed density and their weed biomass as compared to weedy check. Significantly highest bulb yield of onion (322.17 q ha-1) was noted under hand weeding twice at 20 and 50 DAT, however, it was statistically followed by oxyfluorfen @ 0.25 kg ha-1 as PE fb one hand weeding at 45 DAT (291.95 q ha-1), pendimethalin @ 1.5 kg ha-1as PE fb one hand weeding at 45 DAT (288.77 q ha-1) and oxadiargyl 0.080 kg ha-1 as PE fb one hand weeding at 45 DAT (285.66 q ha-1). Hand weeding twice at 20 and 50 DAT gave maximum gross return (Rs.281500.00 ha-1) and B:C (2.93), whereas, net return (Rs.185465.00 ha-1) and benefit cost ratio (3.07) was highest under oxyfluorfen @ 0.25 kg ha-1 as PE fb one hand weeding at 45 DAT. All these economic parameters were found minimum under weedy check.
