An experiment was conducted during autumn season of 1999 to examine the effects of three set sizes: 10-15, 16-20 and 21-25 mm diameter on bulb size, bulb yield, maturity and bolting response in five cultivars of onion namely Burgundy, Texas Early Grano, White Creole, Swat No.1 and Phulkara, in Islamabad, Pakistan, during 1998-99. Bulbs developing from large sets (21-25 mm) showed significantly higher percentage of bolting (40%) than medium (29.4%) or small sets (20.8%).
