Abstract

The effects of seedling/set size and planting times on bulb yield and quality in onion cultivar Phulkara were studied during autumn season 2000. The bulbs of seedlings and sets were graded in three sizes of 2.5, 3.5 and 4.5 mm diameter and 7.5, 12.5 and 17.5 mm diameter, respectively and were sown on 15th August and Ist September, 2000. Highest mean marketable bulb yield (21.2 tha-1) was obtained using 17.5 mm diameter size sets and seedling with 4.5 mm diameter bulbs. However, the crop sown with 17.5 mm diameter sets on 1st September, produced significantly highest marketable bulb yield of 24.6 tha-1 and also gave highest percentage of doubles (17.9 %). Sets with 17.5 mm diameter though produced highest percentage of doubles but also gave highest marketable bulb yield and are therefore recommended for planting autumn season crop in first week of September.
