The present investigation entitled, “Studies on weed management in Rabi onion (Allium cepa L.)” was carried out at the Vegetable Research Farm of Chandra Shekhar Azad University of Agriculture & Technology, Kanpur (U.P.) during Rabi season 2021with the objectives of relative efficacy of herbicides and hand weeding on weed control in onion. The experiment was laid out in Randomized Block Design for nine treatments with three replications. It was observed that the growth attributes viz., plant height (80.25 cm), leaves/plant (10.82), fresh weight of bulb (32.65 gm) and dry weight of onion (17.51 gm) were significantly higher in (T2) over rest treatments, respectively. The yields attributes viz., the polar diameter of bulb (56.70 mm), Equatorial diameter of bulb (68.58 mm) and total bulb diameter (5.97 cm) were significantly more recorded in T2, while the minimum was recorded in control. The bulbs yield (27.03 t / ha). TSS (15.43) was significantly highest in weed free check over remaining all treatments, respectively. Among the herbicidal treatment pre and post emergence application of treatment T8. The number of weeds (m2) and weed dry matter (g/ m2) were significantly noticed that weed free check (T2) was most effective treatment as it recorded less weed count 0.68/m2 and dry matter 1.25g followed by 3.63/m2 and 3.45g, respectively. The maximum weed control efficiency (93.3%) and minimum weed control index (0.00%) was significantly recorded by treatment T2, compared to remaining treatments, respectively. The gross monetary returns (Rs.3,24,360.00) were recorded higher in the treatment weed free check (T2) followed by among the herbicides T8 Rs 3,15,240/ ha and net monetary returns were recorded statistically higher in the treatment T8 Rs. 2,21,648.00. Whereas, the highest benefit cost ratio (1:3.71) was recorded in the treatment T7 followed by T6, in the present investigation.

“…It's possible that less crop weed competition preserved a large ~ 756 ~ amount of nutrients for the crop and led to profuse growth, which allowed the crop to absorb more soil moisture and nutrients from deeper soil layers, which is why traits like bulb weight, polar diameter, and equatorial diameter are associated with higher yields. These outcomes resemble those published by Patel et al (2011) [11] , Apurva et al (2018) [2] , and Sourabh et al (2020) [19] .

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 preplanting 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.

“…In India, it is planted over an area of 1.43 million ha with an annual production of 26.15 million tons (DAC andFW, 2019-2020). The principal reason for low onion productivity is its long-duration cultivars (120-180 days), which suffer from successive weed flushes (Minz et al, 2018). Furthermore, reduced smothering effects attributed to the short stature of the onion plants, characterized by narrow, erect, and smaller leaf size, coupled with the slow early-stage vegetative growth of onions, result in significant competition from weeds.…”

Weed control poses substantial difficulties for winter season onion (Allium cepa L.) cultivation in the north-western Indo-Gangetic Plains, primarily due to the constrained efficacy of the existing herbicides. To address this issue, a 2-year field study was conducted to assess the efficacy of pre- and post-emergence herbicides (pendimethalin, ethoxysulfuron, imazethapyr, and quizalofop-p-ethyl) individually and in combination with crop residue mulch for weed control in winter onion. The results revealed that using herbicides or mulches in isolation did not provide satisfactory weed control. However, the integration of natural mulch with pendimethalin followed by quizalofop-p-ethyl application proved to be the most effective weed control strategy, resulting in the least reduction in bulb yield (10.3%) compared to other treatments. On the contrary, combinations of pendimethalin with ethoxysulfuron or imazethapyr showed adverse effects on the onion crop and inflicted the highest yield losses among all treatments (78.6 and 83.4%, respectively). However, the combination of pendimethalin with quizalofop-p-ethyl coupled with crop mulch resulted in season-long weed control and over 80% bulb yield (36.58 t/ha) gains compared to the weed-free condition. These findings emphasize the efficacy of combining herbicides and mulches as an integrated weed management strategy for onions. By adopting such integrated approaches, farmers could improve weed control while maintaining bulb yield and quality, reducing the risks associated with herbicide resistance, and promoting sustainable onion production in the north-western Indo-Gangetic Plains.
