Effect of Plant Population Densities on Yield and Quality of White
Dehydration Onion in the Northern Sudan
Gafar H. Mohammedali
Abstract:
Field experiment were conducted at Hudeiba Research Station in the arid
region of Northern Sudan during the three seasons: 1985-86, 1986-87 and
1987-88 to evaluate the effects of two plant population densities on
yield and quality of three newly developed white dehydration onion
varieties.
Results indicated that the three varieties were not significantly
different (P= 0.05) in their total bulb yields in the three seasons.
Closer in-row spacing of 5 cm consistently gave higher total bulb yield
due to the increased plant population per unit area with a mean yield
advantage of 19% compared to the wider in-row spacing of 10 cm. The
varieties were comparable in their quality characteristics. However,
‘Hudeiba White’ consistently had small sized bulbs, and ‘ElHilo’ had
less tendency for premature bolting. Wider in-row spacing gave larger
bulbs. Interaction of variety X spacing consistently had no significant
effects (P=0.05) on total bulb yield in the three seasons.
