Abstract

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.
