Abstract
2 Abstract: A field experiment was conducted at Experiment Station of the Faculty of Agriculture, Cairo, University, Giza Governorate during 2008/2009 and 2009/2010 seasons, to study the influence of planting date (15 November, 15 December and 15 January) on seed production of onion (Allium cepa L.) cv. Giza 20. Results of planting date showed significant effect for most of studied characters. The highest significant increases of scapes number/ plant, scape diameter, main scape length, umbel diameter, seed yield /plant, seed yield /fed, weight of 1000-seeds and percentage of seed germination were resulted from planting on mid of November, Meanwhile the lowest significant values were recorded with delaying planting up to mid of January. On the other hand, sprouts number/plant was not affected by planting dates. It could be concluded that the favorable planting date to produce high seed yield with best quality is mid of November for Onion Giza 20 cultivars under Giza region.
