تزداد أهمية التنبؤ باستجابة إنتاجية المحاصيل المختلفة لمستوى الري لدوره في تحديد معدل الـري
الأمثل في ظروف محدودية توافر المياه، و بغية الاستمرار في الإنتاج و تحقيق الريعية العالية. أُجريت هذه
الدراسة بهدف تقييم قدرة البرنامج CropWat على التنبؤ بتأثير الري الناقص فـي محـصول القطـن
و لإيجاد بعض الخيارات البديلة لري محصول القطن. جمعت بيانات إنتاجية المحصول و استهلاكه المـائي
من التجارب الحقلية لثلاثة مواسم متتالية (2007 – 2009) لتقييم مدى استجابة محصول القطن المروي
بالتنقيط للري الناقص (DI).
Predicting crop yield response to irrigation level is increasingly important to
optimize irrigation under limited available water and for enhancing
sustainability and profitable production. This study was carried out to evaluate
the performance of CropWat model in predicting deficit irrigation effect on
cotton crop, and to explore some alternatives for cotton irrigation. Crop yield
and water use data were collected from a 3-yr (2007-2009) field experiment to
assess the response of drip-irrigated cotton to deficit irrigation (DI).
