Abstract:

The study was conducted during 2023-24 at instructional farm of BTC College of Agriculture and Research Station, Bilaspur (C.G.). to “Study of weed management practices on growth, yield and yield attributing characters on rabi season Onion (Allium cepa L.) cv. N-53”. The experiment was laid out in a randomized block design with eight treatments including T1: (Control), T2: (Pendimethalin 30% EC @ 1 kg a.i.as pre-emergence) T3:(Quizalofap-p-ethyl 5% EC @ 50 g a.i.as Post-emergence), T4: Fluazifop-p- butyl 11.1% SL @ 0.125 kg a.i.as Post-emergence), T5: (Pendimethalin 30% EC @ 1 kg a.i. as pre-emergence + Quizalofap-p-ethyl 5% EC @ 50g a.i.as Post-emergence), T6: (Pendimethalin 30% EC @ 1 kg a.i. as pre-emergence + Fluazifop-p-butyl 11.1% SL @ 0.125 kg a.i.as Post-emergence), T7: (One Hand Weeding at 30 DAP) and T8: (Weed Free).

Various growth parameters like plant height, number of leaves, neck thickness were recorded at 30, 60 and 90 days after transplanting and at harvest. Plants in the T8: (Weed Free) treatment recorded significantly highest values for all the growth parameters compared to the T1: (Control). Yield attributes such as bulb diameter, bulb weight were also highest under T8: (Weed Free) condition. Total bulb and marketable bulb yield were maximum with T8: (Weed Free) treatment recording 194.45 and 189.39 q ha-1 respectively which was significantly at par with the treatment T6:(Pendimethalin 30% EC @ 1 kg a.i. as pre-emergence + Fluazifop-p-butyl 11.1% SL @ 0.125 kg a.i.as Post-emergence). The experimental field was infested with various weed species and sedges. Weed density and dry weight were lowest under weed free treatment (T8), while highest density and dry weight were recorded with control treatment (T1).The study found that the most economical and profitable treatment for rabi onion cultivation was T6: (Pendimethalin 30% EC + Fluazifop-p-butyl 11.1% SL), with the highest gross and net returns.The study highlights the importance of timely weed control in rabi onion for increased growth, yield, and net returns, emphasizing the need for integrated weed management for onion productivity and profitability.
