ملخص المقالة :

مطالعه‌ی حاضر، با محاسبه‌ی بهره‌وری فیزیکی و اقتصادی آب در محصولات زراعی و باغی شهرستان دزفول در سال زراعی 96-1395، این محصولات را از نظر بهره‌وری آب اولویت‌بندی نموده است. همچنین عوامل موثر بر بهره‌وری فیزیکی و اقتصادی آب با استفاده از یک مدل رگرسیون، تعیین گردید. داده‌های مورد نیاز با روش نمونه‌گیری تصادفی طبقه‌ای و با تکمیل پرسشنامه از یک نمونه‌ی 221 نفری از کشاورزان شهرستان مذکور، به دست آمد. نتایج نشان داد که، بالاترین بهره‌وری فیزیکی آب به ترتیب مربوط به محصول کاهو (8/22 کیلوگرم بر مترمکعب)، هویج (03/15 کیلوگرم بر مترمکعب) و پیاز (19/9 کیلوگرم بر مترمکعب) و پایین‌ترین بهره‌وری فیزیکی آب مربوط به نارنج (67/0 کیلوگرم بر مترمکعب) و گریپ‌فروت (84/0 کیلوگرم بر مترمکعب) می‌باشد. نتایج تحلیل رگرسیون نیز نشان داد که متغیرهای نوع محصول، سن، سابقه‌ی و تحصیلات کشاورز، سطح زیرکشت، داشتن شغل غیرکشاورزی، نوع منبع آب و روش آبیاری بر بهره‌وری فیزیکی و متغیرهای سن و سابقه‌ی کشاورز، شغل غیرکشاورزی، بافت خاک و نوع منبع آب بر بهره‌وری اقتصادی آب موثرند.
