“…From the obtained results, it is possible to understand that weed management of onion through manual weeding for appropriate frequency of weeding at the right weeding interval played an important role in increasing onion bulb yield, which could be attributed to their favourable effects on bulb yield contributing parameters such as number of leaves per plant. As noticed by Shah et al (1996), Dhananivetha et al (2017 and Pushpa and Choudhary (2019), accurate manual weeding through frequency of weeding and at the right time of weed removal significantly reduced weed infestations and better in increasing the onion growth and yield parameters when compared with weedy check plots.…”

“…Weed management is one of the most important agricultural production practices. A number of weed management practices have been reported, including use of cultural, mechanical, herbicidal and the use of organic and inorganic mulches (Pushpa and Choudhary, 2019). To manage weeds effectively, weed management should contest with the specific problems under field condition.…”

Field experiment was conducted at Arba Minch during 2017 and 2018 cropping seasons under irrigation condition to determine the effect of weeding frequency and interval on weeds and bulb yield of onion. The experiment was laid out in factorial arrangement in randomized complete block design with three replications and comprised of 18 treatments: four weeding frequencies (2, 3, 4 and 5 times) and four weeding intervals (at 10, 13, 17 and 25 days) compared with weedy and weed-free checks. Results showed that all the parameters considered in this study were significant (p<0.05) among the treatments. The lowest weed density (27.33 m-2 in 2017 and 24.26 m-2 in 2018) and dry weed biomass weight (0.83 t ha-1 in 2017 and 0.82 t ha-1 in 2018) were recorded in the weed free check without statistical difference with the values received from weeding interval at 10, 13 and 17 for four and five times weeding frequency in both cropping seasons. The highest weed control efficiency (83.70% in 2017 and 82.82% in 2018) was computed in the weed free plots. In the 2017 cropping season, the highest marketable bulb yield (32.8 t ha-1) was recorded in the weed free check, which was statistically similar with the result obtained in four and five times weeding frequency at 10, 13 and 17 days weeding interval. Similar trends were observed during 2018 cropping season. Thus, three to five times frequency of weeding at 10 days weeding interval could be recommended in the study area for efficient weed management and optimization of the bulb yield and profits in onion production.

“…Pathogens such as fungi, bacteria, nematode, pest and insects that attack vegetable crops during planting, growth phases and storage reduced the quality and yield of the crops. However, weeds are the major cause of low yield in Allium cepa in productivity due to slow germination, nature of the leaves that are narrow upright and do not shade out (Ujjainiya & Choudhary, 2019). The degree of damage caused by weeds is related to the type, species and density of weeds growing in a crop community.…”

“…The degree of damage caused by weeds is related to the type, species and density of weeds growing in a crop community. Species of weed are usually found distributed and this varies with season, availability of water, soil type and types of cultivar species in a particular field/farm or region (Ujjainiya & Choudhary, 2019). In Aliero, farmers prepared cultural weed control method due to availability of laborers, traditional equipments such as hoe and size of the farm.…”

Allium cepa (Onions) is one of the major vegetables that is consumed all over the world after tomatoes due to is active compounds but weeds infestation during growth phase are the major challenge faced by the farmers which result in a very poor growth and yield of this spice. In this study, the conventional hand weeding practices were compared with weedicide pendimethalin to control different weeds and the morphological characters such as; number, size, height, neck area and fresh weight of the onions bulbs planted at Department of Plant Science and Biotechnology, Botanical Garden, KSUSTA. Twelve (12) weeds of different family were found and identified from the experimental field namely; Urena lobata, Eragrostis tremula, Amaranthus viridis, Senna occidentalis, Cenchruse chintus,

Two field experiments were conducted during 2015/2016 and 2016/2017 seasons at Shandaweel Agriculture Research Station, Sohag Governorate, to study the effect of onion density and weed control treatments on vegetative growth, yield and quality of onion. Split plot design with three replicates was used. Onion plant density (240 000, 300 000, and 400 000 plant/ fed.) occupied the main plots, whereas weed control treatments (hand hoeing (twice), Goal + Select (once), Goal + Select (twice), Ecopart + Select (once), Ecopart + Select (twice) and control) occupied the sub plots. Onion plants grown under the highest density (400 000 plants/fed.) attained the highest values of plant height and number of leaves/plant, while the lowest density (240 000 plants/fed.) attained the lowest values, in both seasons. Total yield/fed. for onion grown under high density were higher than those under other densities. Planting onion at low density recorded the highest values of single bulbs%, and double bulbs%, while planting at high density recorded the lowest values, in both seasons. The highest values of number of leaves/plant and bulb weight were obtained by application of Goal + Select (twice), in both seasons. Average bulb weight, marketable yield/fed., culls yield/fed. and total yield/fed. were significantly decreased under weed control treatment, in both seasons. From this investigation, it could be concluded that using of the highest plant density (400 000 plant/fed.) and application of Goal + Select (twice) could be recommended for the highest values of gross income, net benefit and the percentage of benefit/cost ratio.
