Abstract
This study was conducted during the two fall seasons of 1995 and 1996 at Sids Horticulture Experiment Station to stud1 four planting dates of squash us" August, 1st September, is" September and 1s October), the Eskandarani variety was used in the experiments. These experiments was to study the effect of planting date on growth, yield, fruit quality as well as the spread of cucurbita viruses on squash plants during these planting dates. The obtained results indicated that increasing the percentage of infection squash plants with virus diseases was increased in the first, second and third planting dates, while was lower in fourth planting date. The first planting date gave highest infection percentages with virus diseases, which were 100% and 97.9% in the first and second season, respectively, while were 25.6% and 20.3% for fourth planting date in both season, respectively. These differences of infection percentage of plants between various planting dates were reflected on vegetative growth, yield component and fruit characteristics, where as, the fourth planting date gave significantly higher in all measurements of growth, yield and fruit quality under this study, while the first and second planting dates were low values of all measurements under the study. The third planting date was medium of percentage of non marketable yield because the late infection with virus diseases. In summary to get good squash yield and best quality, sowing of squash plants in fall season at middle of Egypt sowing could be during October month.
