“…Maximum B: C ratio in the interaction of early planting and closer spacing maybe because of higher yield, thereby increasing the monetary returns, whereas low yield per hectare might be the reason for comparatively low returns, thereby lower the ratio of benefit to cost. The result was in agreement with the findings of Devi et al, (2008) and Misra et al, (2015).…”

Multiplier onion (Allium cepa L. var. aggregatum Don.) is also known as Aggregatum onion, potato onion, small onion, underground onion is a biennial herbaceous plant that belongs to the family Alliaceae (Pandey, 2006). Depending on the plant's genetic character, 3-20 bulbs are observed in each plant (Brewster, 2008). It is commonly propagated by small bulbs (bulblets). Multiplier onion has good keeping quality and better tolerance for extreme climatic conditions, pests, and diseases than a common onion (Brewster, 2008). Multiplier onion is grown on a commercial scale for internal consumption and export purpose in countries like

“…The higher yield of onion with close spacing was earlier reported by which is similar to our observation; however, reported higher bulb yield with wider spacing (Sikder et al, 2008;Jilani et al, 2010;Mekonnen et al, 2017;Chanu et al, 2022;Mazumder et al, 2019). The effect of different spacing on the growth parameters of onion was earlier reported by and others, confirmed their findings through the extent of difference in different traits different from them (Kahsay et al, 2013;Misra et al, 2014;Islam et al, 2015;and Derajew et al, 2017). In the different nitrogen doses tried, the highest value of growth traits namely number of leaves, leaf length, pseudostem length, and plant height were obtained with the application of 150 kg N/ha.…”

The present research was conducted in the research farm of Takhar University, Afghanistan. The study was carried out in 2021, to document the Effect of Nitrogen and Plant spacing on the Growth and Yield of Onion and it is one of the essential bulbous vegetables. The experiment was laid out in Split Plot Design having three replications were used. Four different doses of nitrogenous fertilizer namely 0, 100, 125, and 150 kg/ha were applied. The treatments also included three levels of spacing (S) viz., S1= 7.5 cm × 15 cm, S2= 10 cm × 15 cm, and S3= 12.5 cm × 15 cm. These treatments were implemented using a split-plot design. As a result, the spacing had a significant effect on biomass and marketable yields, and the spacing of 7.5 cm×15 cm resulted in the maximum marketable yield of 31.24 t/ha likely due to a higher plant population. Various nitrogen doses as well as affected plant characteristics and yield. The maximum biomass yield of 62.52 t/ha was recorded with 150 kg nitrogen/ha. Whereas the highest marketable yield 38.62 t/ha was observed with 125 kg nitrogen/ha. In conclusion, spacing and different nitrogen concentrations had significant impacts on plant characteristics and yield. These findings highlight the importance of enhancing spacing and nitrogen doses to maximize crop yields.

“…It is an accepted fact that weather conditions play major role in production and productivity of agricultural crops. The wide variation in planting dates of onion among regions shows effect of environment on onions' growth and yielding capacity (M. Ali, 2016;Misra et al, 2014;Navaldey & Ram, 2014).…”

This investigation was carried out during 2018 and 2019 at the research farm of the Agriculture Faculty of Kabul University, Afghanistan to study the correlation between weather conditions (maximum, minimum and mean temperature, relative humidity, cumulative day light and cumulative rainfall) and onion plant growth, yield and bulbs quality, as well as to find the optimal planting date for onion variety Safid e Paisaye. The data was analyzed with STAR software. The results of this study reveal that, increasing temperature and decreasing relative humidity and rainfall during growing season, caused faster maturity of bulbs, produced small sized bulbs, and finally reduced onion bulbs yield. It was observed that, due to relatively lower temperature and higher relative humidity during early growth stages the onion grown early in spring (seed sown in early March and transplants planted early in May) took longer period for maturation, produced larger bulbs and higher yield. This was also noted that due to longer maturation period the onion plants grown in early spring received a higher cumulative heat and sun light which contributed to improve bulbs quality and yield of onion. Based on this study results it is concluded that, early planting date of onion variety Safid e Paisaye not only increased significantly yield but also improved bulbs quality.
