“…The explanation of low density on these characters may be attributed to reduce competition for moisture and nutrients at low dense plants that resulted in bulbs with higher bulb weight and bigger diameter, when extra plants are overcrowded per meter, leaves are overlapped at an early stage and the benefits from light interception, on a ground area basis, are eroded. Similar results were obtained by Geries et al (2015), Islam et al(2015), Shock et al(2015), Ali et al (2016 a&b) and Gaharwar et al (2017).…”

“…Because weed population and weed growth remain less during the entire crop growth, which leads to increase in various growth parameters of onion and the recover in bulb yield. Similar results were obtained by Hussain et al (2008), Kalhapure (2013), Elian et al (2016) and Gaharwar et al (2017) and Ramalingam et al (2017).…”

“…Meantime, unweeded check listed the lowest values of plant height, number of leaves/ plant, bulb diameter and plant dry weight of onion plants, followed by hand hoeing twice and Stomp extra alone in both seasons. Similar results of application of oxfluorfen in onion were also reported by Gaharwar et al (2017), Ramalingam et al (2017) andkumara et al (2018).…”

“…Hence, weed competition by post emergence herbicide implementation was furthermore enhanced by combination hand hoeing at 45 DAT in weed control treatments, which provides efficient and prolonged weed control and kept the crop weed free during the critical periods of competition. These results are in harmony with Khokhar et al (2006), Chandrika et al (2009), Kalhapure et al (2014) and Elian et al (2016), Gaharwar et al (2017) and Ramalingam et al (2017).…”

“…This was a natural result to the reduction occurred on weed growth which reflected positively on crop development consequently, rising economic return. In this concern, Sraw et al (2016), Abdelmasieh (2017), Abou Khadrah et al (2017 and Gaharwar et al (2017) displayed similar findings.…”

Two field experiments were carried out during two successive winter seasons (2016/17-2017/18) at Agricultural Research Station, Kafr El-Sheikh Governorate, Agricultural Research Center, to study the effect of twenty four treatments which were a combination of eight weed control treatments (i.e., Against, Against with hand hoeing once, Floro, Floro with hand hoeing once, Stomp extra, Stomp extra with hand hoeing once, hand hoeing twice and unweeded check) and three planting population including 120, 180 and 240 thousand plants/fad on weeds control, growth characters, onion production and its quality. All tested weed control treatments significantly increased onion growth characters and yield during the two seasons. Weed control treatment by Floro at rate of 750 cm 3 /fad+ hand hoeing once at 45 days after transplanting, reduced percentage of dry weight of broad-leaved, grassy and total weeds at 60 and 90 days after transplanting by (97.08 & 96.39 %), (90.50 & 90.50%) and (96.20 & 95.20 %) in the average survey in 2016/17 and 2017/18 seasons, respectively, compared to unweeded check. The same treatment produced the highest average bulb weight, marketable and total bulbs yield per fad by about 45.67, 74.56 and 59.78 % when compared with unweeded check in the average of both seasons, respectively with best storability along with bulbs quality at low cost of onion production, demonstrate that weed control is very important in the onion fields. Also, onion plant grown at 180 thousand plants/fad revealed a very promising effect for marketable and total yield with the average of 17.89 and 20.24 % in conjunction with a great reduction in the total weed biomass/m 2 at 60 and 90 days after transplanting by about 25.51 and 25.77 % in the two seasons compared to 120 thousand plants/fad., respectively. The maximum values of total soluble solids, percentage of dry matter in bulbs, and remaining marketable bulbs after storage for six months were achieved under the density of 120 or 180 thousand plants/fad in both seasons. Total bulb yield/fad showed highly significant negative correlation with each of dry weight of broad-leaved, grassy and total weeds as well as culls yield/fad. Therefore, the use of integration between Floro EC 24% as post-emergence herbicide at rate of 750 cm 3 /fad (21 days after transplanting) followed by hand hoeing once at 45 days after transplanting plus plant density of 180 thousand plants/fad is the best choice for the onion farmers of this area to achieve maximum onion bulb yield/fad, storability and quality of onions with higher economic returns.

The studies carried out in the years of 2014–2017 at the Institute of Horticulture in Skierniewice were aimed to compare the biological effectiveness of foliar applied herbicides: oxyfluorfen, prosulfocarb, bromoxynil, pyridate and their mixtures, as well as assessment of suitability of these substances for weeds control in sowed onion. Herbicides were applied with the split application method, in three treatments, every 5–8 days from 1‒2 true leaves stage of onion or in two treatments from 2–3 leaves of onion. The studies assessed the effect of herbicides and their mixtures on the degree of weed damage, secondary weed infestation, selectivity, as well as onion growth, development and yield. The results showed that the greatest reduction of weeds and the highest yield, with slight, transient phytotoxicity symptoms, were obtained after 3 times spraying with oxyfluorofen in a mixture with bromoxynil. The weakest weed control and the lowest onion yield were obtained after applying oxyfluorfen in two treatments, in a mixture with pyridate.

A field experiment was conducted to find out appropriate nutrient and weed management practices for yield maximization and nutrient uptake of onion during rabi 2018-19 at the experimental plot of Regional Research and Technology Transfer Station, Keonjhar of Odisha. The experiment was laid out in Split plot technique with fifteen treatments viz., Main plot belongs to Nutrient management (N) with treatments i.e. N1- Soil test based fertilizer recommendation (STBFR), N2 - 50% STBFR + FYM (Based on N requirement), N3-STBFR + Sulphur), while Subplots belongs to weed management (W) with treatments viz., W1- Pendimethalin (PE) @ 0.8 Lha-1, W2- Oxyflurofen (PE) @ 0.2 Lha-1, W3-Pendimethalin (PE) @ 0.8 Lha-1+ one hand weeding at 25 days after transplanting(DAT), W4-Oxyflurofen (PE) @ 0.2 Lha-1+ one hand weeding at 25 days after transplanting(DAT), W5- one hand weeding at 25 days after transplanting (DAT). The highest onion bulb yield of 16.72 t ha-1 was obtainedunder the treatment applied with Pendimethalin (PE) @ 0.8 Lha-1 along with one hand weeding at 25 DAT, followed by Oxyfluorfen 0.2Lha-1 pre-emergence + 1 hand weeding at 25 DAT (15. 88 t ha-1). The treatment combination of N2W3 (96.83, 16.80, 57.73 kg ha-1) was recorded the highest N, P, and Kuptake by crops respectively while N3W3 (51.39 kg ha-1 ) was recorded as the highest S uptake by a crop over the rest of the treatments.
