| چکیده | ||
| با توجه به کمآبی و خشکسالیهای اخیر اهمیت بهرهوری آب بیشتر مشخص میشود. بر این اساس هدف این پژوهش تعیین بهرهوری آب گندم در شهرستان ارزوئیه میباشد. بدین منظور نیاز آبی با استفاده از داده‌‌های ایستگاه هواشناسی منطقه مورد مطالعه و نرمافزار CROPWAT محاسبه گردید. همچنین به منظور تأیید مقادیر حاصل از نرمافزار CROPWAT مقدار پتانسیل تبخیرتعرق با استفاده از فرمولهای هارگریوز-سامانی و جنسن-هیز نیز محاسبه شد. بر طبق آن جهت تعیین میزان حجم آب مصرفی گندم در واحد هکتار در طول دوره رشد، میزان هیدرومدول برای منطقه مورد مطالعه برآورد شد. با توجه به نتایج، مقدار بهرهوری فیزیکی گندم برابر 6/1 کیلوگرم بر مترمکعب و مقدار بهرهوری اقتصادی آن برابر 13000 ریال بر متر مکعب، حاصل گردید. نتایج بیانگر آن است که در صورت تأمین نیاز آبی واقعی گندم و مدیریت صحیح آبیاری در مزارع، محصول گندم دارای بازده اقتصادی زیادی در سال 98-97 میباشد. | ||

| چکیده [English] | ||
| Due to the recent water shortages and droughts, the importance of water productivity is becoming more apparent. The main objective of this study is to examine water productivity of wheat according to its water requirement and proper irrigation management. This research was performed in Orzouieh city of Kerman province located in an arid region. In this study by using meteorological data of the region, wheat evapotranspiration was calculated by CROPWAT. Then, potential evapotranspiration was also calculated by Hargreaves-Samani and Jensen-Haise methods to verify the values resulted by CROPWAT package. Irrigation Hydromodule was calculated too. The Volume of water consumed by wheat per hectare during growing season was also calculated using irrigation hydromodule. For performing this study, three wheat farms with proper irrigation management were selected. For calculating physical and economical productivity of wheat farms in the region, one of the farms was examined. The results of this study showed that the physical productivity (CPD) is equal to 1.6 kg/m3 and economical productivity (NBPD) is equal to 13000 Rls./m3. The calculated productivities demonstrate that supplying actual water requirement of wheat along with proper management of the fields, results high economical efficiency. | ||
