摘要

Field experiment was conducted at Humbo Larena, wolaita zone during the 2012/2013 dry season, to study the effect of bulb treatment and spacing patterns on seed yield and quality of onion in the semi-arid zone of Ethiopia. Treatments consisted of a factorial combination of four levels of bulb types [whole bulbs, cut (topped) bulbs, ash-treated cut (topped) bulbs, and fungicide-treated cut (topped) bulbs] and four levels of spacing patterns (50 x 30 x 20 cm, 60 x 30 x 20 cm, 40 x 20 cm, and 50 x 20 cm) laid out in randomized complete block design replicated three times. The onion variety known as Bombay Red was used as a test crop. Results revealed that the main effects of both bulb treatment and spacing significantly influenced, seed weight per umbel, standard germination, vigour Index I and vigour index II. However, bulb treatment and spacing interacted to significantly influence seed yield. The highest seed yield was obtained in response to planting fungicide-treated topped bulbs at the both double-row spacing. However, significantly higher values of all seed quality parameters were obtained from both single-row spacing.
