Assessing the Impact of Climatic Fluctuations on Weed Management in Onion (Allium cepa L.) Bulb Production
Keywords:
Weed Management Practices, Weed Control Efficiency, Onion, Hand WeedingAbstract
The study, carried out over two successive Rabi seasons in 2016-17 and 2017-18 at SKN College of Agriculture in Jobner, focused on assessing how climatic variations influenced the effectiveness of various treatments on onions grown in loamy sand soil. Results exhibited that weed control efficiency and yield of onion not only influenced by weed management practices and nitrogen levels but also due to seasonal variation of climatological factors during two years of experiment. In the agricultural trials conducted for a period of two years, it was observed that the combination of two hand weedings and the application of 100 kg of nitrogen per hectare, or the use of pendimethalin plus oxadiargyl at 40 days after transplanting (DAT) along with the same amount of nitrogen, yielded results that were statistically comparable. These methods demonstrated the influence of climatic conditions on the efficacy of weed management and the subsequent yield of onion bulbs.
