چکیده

افزایش تولید از طریق افزایش سطح زیرکشت با محدودیت‎هایی ازجمله محدودیت منابع آبی مواجه است. لذا با افزایش عملکرد می‎توان به افزایش تولید دست پیدا کرد. در این خصوص مطالعه بهره‎وری عوامل تولید بسیار حایز اهمیت است. در همین راستا این مطالعه با هدف اندازه‎گیری بهره‎وری عوامل تولید چغندرقند در استان فارس صورت گرفت. داده‎های موردنیاز این مطالعه از طریق تکمیل پرسشنامه در میان 65 چغندرکار استان فارس در سال زراعی 1387 گردآوری گردید. برای محاسبه بهره‎وری نهاده‎ها از تابع تولید درجه سوم استفاده شد. نتایج نشان داد که بهره‎وری نهایی تعداد دفعات آبیاری، نیروی کار مزد بگیر، کود حیوانی، کود فسفاته، سم و سطح زیرکشت به ترتیب برابر با 385، 28-، 4/0-، 14، 2574 و 1253- می‎باشد. هم‎چنین مشخص گردید 1/97 درصد بهره‎برداران از کودحیوانی و 8/61 درصد آنها از آب بیش از حد بهینه استفاده می‎کنند. کاهش استفاده از نیروی کار و کود حیوانی به‎عنوان پیشنهاد مطالعه مطرح گردید.

چکیده [English]

Production is hard to achieve by increasing cropping area due to limited water resources. So, increased yield per unit area may be the solution to increase production. Investigating productivity of production factors is very important in this context. The objective of this study is to measure the productivity of production factors in sugar beet production in Fars province. The data needed for the study was gathered by completing questionnaires among 65 sugar beet growers of Fars province in growing season of 2008. The polynomial production function of order three was used to estimate the applied inputs productivity. The results showed that marginal productivity of the inputs including irrigation times, hired labor, animal manure, phosphate fertilizer, poison and cropping area are 385, -28, -0.4, 14, 2574, and -1253, respectively. It was also found that 97.1 percent of the farmers have overused animal manure and the corresponding figure for water was 61.8 percent. Reduction in labor and animal manure use is recommended.
