| چکیده | ||
| چغندرقند یکی از محصولات صنعتی بخش کشاورزی است که نقش مهمی در تأمین شکر موردنیاز داخل دارد. بررسی کارایی تولید چغندرقند عاملی بسیار مهم و تأثیرگذار در افزایش تولید و عملکرد آن، بدون نیاز به هزینههای اضافی میباشد. در این مطالعه، انواع کارایی فنی، مدیریتی و مقیاس برای تولیدکنندگان چغندرقند دشت قزوین با استفاده از روش تحلیل پوششی دادهها مورد بررسی قرار گرفته است و همچنین میزان بهینهی نهادهها برای دستیابی به بیشینهی کارایی تولید این محصول بررسی گردید. اطلاعات و دادهها از طریق تکمیل 60 پرسشنامه در سال زارعی 89-1388، جمعآوری شده است. نتایج نشان داد که میانگین کاراییهای فنی، مدیریتی و مقیاس تولیدکنندگان چغندرقند در منطقه به ترتیب برابر 6/89، 5/70 و 79 درصد بوده است. همچنین نهادههای کود، نیرویکار و بذر بیشاز مقدار بهینه و نهادههای سم و آب کمتر از میزان بهینه بهکار گرفته میشوند. | ||

| چکیده [English] | ||
| Sugar beet as an industrial crop plays a main role in satisfying domestic demand of sugar. Study on the production efficiency of sugar beet is important because this is a factor that influences production without additional cost. In this study, Data Envelopment Analysis approach (DEA), was implemented to calculate technical, administrative and scale efficiency of sugar beet production. Also optimum level of inputs was determined. Data was collected from 60 questionnaires filled by sugar beet producers in 2009-2010. Results indicated that average of technical, administrative and scale efficiency is equal to 89.6%, 70.5% and 79%, respectively. Also, fertilizer, labor and seed were used more than optimum level whereas herbicide and water were implemented less than optimum level. | ||
