The effects of three garlic clove sizes and four sides of ridge planting on crop establishment and yield and quality of bulbs were investigated at Shambat, Khartoum North, Sudan in 1990/91 and 1991/92 winter seasons. Clove size resulted in a notable differential response in crop establishment, vegetative growth and yield; yet the differences were not significant. The highest percent of crop emergence occurred when planting was on the northern side, followed by planting on the eastern, western and southern sides of the ridge. The pattern of crop development followed the same trend through to harvesting. Yields were significantly different among planting sides. Bulb splitting, as an undesirable character, was significantly different among clove sizes and sides of planting. Percent splitting was positively correlated with clove size and with soil temperature of the planting side. For best utilization of land and input resources, therefore, it may be advantageous to grade cloves so that spacing can be adjusted to clove size to insure more uniform emergence and establishment of the crop, and planting them on eastern and western sides.
