“…To produce higher yield in onion, onion transplants had to be planted at early time (Dec. 1) which allowed development of large vegetative parts (Madisa, 1994;Gonzalez et al, 1997;Derawadan et al, 2002;Bhuiya et al, 2003;Al-Moshileh, 2007). The present results agree with earlier findings of (El-Gamili, 1996;El-Habasha et al, 1985;Islam et al 1999;Khan et al, 2003). They indicated that the production of high onion bulb yield per unit area under the high plant densities is attributed mainly to the increase in the number of bulbs in unit area.…”

“…They reported that total onion yield was increased as the plant spacing decreased and average bulb weight as well as bulb diameter increased with increased the plant spacings. In general, the increase in onion bulb yield per unit area under the higher plant densities might be due mainly to the increase in number of bulbs in unit area (El-Gamili, 1996;El-Habasha et al, 1985;Islam et al 1999;Khan et al, 2003). In addition, with wide distance, the competition between onion plants are minimized and consequently encouraged the capacity of onion plants in building metabolites and increased both diameter and weight of bulb (El-Gamili, 1996).…”

“…In addition, with wide distance, the competition between onion plants are minimized and consequently encouraged the capacity of onion plants in building metabolites and increased both diameter and weight of bulb (El-Gamili, 1996). Onion plants grown at the wide spacing received more soil water, mineral and solar radiation under less interplant competition which promoted vigorous growth resulting in positive bulb traits (Khan et al, 2003).…”

“…The productivity of onion crop is strongly influenced by a number of environmental factors including the cultural practices such as time of planting data (Daymond et al, 1997) and plant density (Khan et al, 2003). Proper spacing ensures optimum plant growth through adequate utilization of moisture, light, spacing and nutrients (Weerasinghe and Fordham, 1994).…”

“…Also, onion is highly sensitive to temperature and photoperiod, so planting date is considered a critical importance in determining onion yield. A number of studies in the world has shown that onion production can be improved through appropriate cultural practices (Weerasinghe and Fordham, 1994;Daymond et al, 1997;Khan et al, 2003). Overwintered onion crop is exposed to a great seasonal fluctuation of temperature and photoperiod, both having a strong influence on onion growth.…”

A field experiment was carried out during 2006/2007 growing season at the Agricultural Research Station, Mu'tah University, Jordan, to study the effect of planting date and plant spacing on onion yield under rain-fed in semi-arid conditions of Jordan. Treatments were arranged in a split plot design with 3 replicates. The main plots were assigned for planting on (Dec. 1, Dec. 15, Jan. 1, Jan. 15 and Feb. 1), while the sub-plots were assigned for plant spacings (10, 15, 20 and 25 cm).Onion bulb yield and bulb weight were decreased with delaying planting date. The highest yield was produced with the earliest planting date (Dec. 1). Neck thick diameter, bulb diameter and bulb height were significantly decreased with delaying planting. Wide plant spacing reduced onion bulb yield, but it significantly increased individual bulb weight, neck thickness and bulb diameter. In general, maximum onion bulbs yield (23.71 ton ha -1 ) was obtained from early planting date with the closest plant spacing. In conclusion, the best onion yield in terms of quantity and bulb characters was obtained when onion transplants were planted on Dec. 1 or Dec. 15 at the closest plant spacing under semi-arid conditions.

Onion (Allium cepa L.) is an important bulb plant grown worldwide. Proper use of the agronomic practice has undoubtedly contributed to growing crop yields. The right level of any farming practice, like the distance between plants, plant density, date of planting, and time of harvest, can produce the wanted outcomes. Therefore, this research was piloted to evaluate the influence of plant spacing on the development of bulb harvest-related traits of onion varieties in Dambi Dollo University, Western Ethiopia, in 2021. Three onion varieties (Adama red, Monarch, Nafis) and four intra-row spaces (6 cm, 8 cm, 10 cm, and 12 cm) in factorial combinations were settled by a complete randomized block design which was simulated three times. The findings of the study indicate that all the factors related to crop growth and bulb yield of onion varieties were mainly influenced by different kinds and plant spacing. Conversely, the collaboration of these two factors did not affect all other factors, but the interaction of the two factors had a great effect on the days to maturity measured in this study. The highest plant height was registered on the onion planted at a distance of 10 cm (59.83 cm) and 12 cm (59.08 cm) distance between plants. The high commercial yields (34.44 t ha−1) and entire bulb yield (35.40 t ha−1) were found in the Nafis variety. The highest marketable yields (31.12 ha−1) and entire marketable yield (31.78 ha−1) were recorded on an onion plant planted 10 cm between plants. Therefore, in the research area, farmers can use a variety of Nafis and a 10 cm distance between plants to increase their onion production.
