| ABSTRACT: The effect of five planting dates i.e., June 15th, July 1st, July 15th, August 1st and August 15th on growth and yield of two cantaloupe (Cucumis melo var. cantaloupensis) hybrids ("Rafegal(c-8)" and "Galia") was studied under Assiut conditions in this investigation. The results indicated that there are no significant differences between cantaloupe hybrids in flowering. "Rafegal(c-8)" hybrid was better than "Galia" in producing total yield, early yield and marketable yield. In addition, fruit of "Rafegal(c-8)" had higher total soluble solids and total sugar content. There were highly significant differences among the five planting dates while, the planting date on July 15th was the best than the other planting dates for most of studied characters. In spite of significant interactions, "Rafegal(c-8)" hybrids still remaining superior to "Galia" and planting on July 15th is the best among other dates for most studied parameters. أجرى هذا البحث بمزرعة محطة البحوث الزراعية بأسيوط التابعة لمرکز البحوث الزراعية، وذلک لدراسة تأثير خمسة مواعيد لزراعة اثنين من هجين الکانتلوب، وهى 15 يونيو، 1 يوليو، 15 يوليو، 1 أغسطس، 15 أغسطس، خلال موسمى الزراعة 2005، 2006 على محصول وجودة اثنين من هجن الکانتلوب وهما جاليا ورافيجال(c-8) تحت ظروف أسيوط. حيث أثبتت النتائج إلى أن هناک اختلافات معنوية بين الهجينين المستخدمين فى الدراسة، وأن الهجين رافيجال(c-8) کان أفضل من الهجين جاليا فى صفات المحصول المبکر- المحصول الکلي- المحصول الصالح للتسويق- نسبة المادة الصلبة الذائبة الکلية والسکريات الکلية. کما أظهرت النتائج أيضاً أن هناک اختلافات معنوية بين مواعيد الزراعة المستخدمة في الدراسة، وأن ميعاد الزراعة 15 يوليو تحت ظروف أسيوط أعطى أعلى القيم فى معظم الصفات المدروسة. کما أظهرت النتائج أيضاً أن التفاعل بين الهجين رافيجال(c-8)، وميعاد الزراعة 15 يوليو کان أکثر معنوية من باقي التفاعلات الأخرى، وأعطى أفضل النتائج في معظم الصفات المدروسة. | ||||
