| Abstract | ||
| Six cultivars of sugar peas (Pisumsativum, L.) Var. Sugar Lace, Mange Tout, Cascadia, Sugar Daddy, Toledo and Giant Sugar, were tested at eight planting dates (1and 15 September, October, November and December) in (2010/2011)and (2011/2012) growing seasons. Significant differences were detected among planting dates in relation to their effects on plant height and total yield. The planting dates of the first and mid October were the best in this regard. Exportable yield was significantly the highest when sown on 1 and 15 October, in both seasons. The first and 15of October and the first of November planting dates did not show any significant differences in the percentage of exportable yield, while, significant differences were found when these dates were compared to earlier or later dates of planting in both seasons, where substantial reduction in exportable yield noticed was occurred. Planting on the first of September resulted in the earliest opened flowering in both seasons. Sugar Daddy had the tallest plants followed by Toledo, Giant sugar, sugar Lace and Mange Tout. Where the first cultivar gave the earliest flowering, followed by Sugar lace, Cascadian, Sugar Daddy and Mange Tout, in both season, and significant differences between cultivars were found . Mange Tout gave the highest yield in the two seasons, while Sugar Daddy showed the lowest total yield in both seasons. The highest amount of exportable yield was obtained from.Mange tout; Sugar Daddy had the lowest yield in both years. Significant differences were found among cultivars in both seasons on the percentage of exportable yield. | ||
