The study was conducted to examine the effect of set size on bolting, bulb yield and quality in onion cultivar Phulkara during autumn season 2001. Highest percentage of bolting (31.1 %) and doubles (69.4 %) was recorded in large sets of 29 mm diameter. In large size sets (29 mm diameter) bulbs matured in minimum time (134.5 days). Highest marketable bulb yield (26 t ha-1) was obtained with 17 mm diameter set followed by 20 and 23 mm diameter yielding 22.9 and 20.0 t ha-1, respectively. Large size sets (26 and 29 mm diameter) produced significantly higher un-marketable bulb yield of 13.9 and 14.9 t ha-1, respectively.
