چکیده

در مطالعة حاضر، به ارزیابی کارآیی عملکرد 23 واحد تولید کاهوی فرانسوی گلخانه‌ای به روش هیدروپونیک عمودی بر مبنای تحلیل پوششی داده‌ها (DEA) در استان البرز پرداخته و مشخص شد که کشت کاهوی فرانسوی بدین روش می‌تواند پرسود باشد، به‏ گونه‏ ای که هزینه تولید هر بوته آن کمتر از پانزده هزار ریال و مقدار فروش هر بوته در حدود صد هزار ریال است. همچنین، ارزیابی چهار نهاده‌ مهم شامل نیروی کار، سرمایه‌ ثانویه (سرمایه‌ مورد نیاز برای تبدیل گلخانه‌های معمولی به ساختار هیدروپونیک عمودی)، کود و سایر هزینه‌ها به‏ عنوان ورودی‏ ها و سود خالص به‏ عنوان خروجی بر حسب میلیون ریال در هکتار صورت گرفت. با توجه به کارآیی فنی و کارآیی مقیاس، بازده نسبت به مقیاس در گلخانه‌های کارآمد «ثابت» و در اکثر گلخانه‌های ناکارآمد «افزایشی» بود؛ و بر اساس نتایج تحلیل کارآیی، گلخانه‌های ناکارآمد واحد‌هایی کوچک با مساحت کمتر از هزار مترمربع بودند که باید مساحت خود را افزایش دهند. این واحدها به ‏منظور دستیابی به کارآیی بالاتر، لازم است در مصرف نهاده‌های یادشده صرفه‌جویی کنند؛ و با مدیریت در استفاده از نهاده‌ها، با هزینه‌ کمتر، به واحدهای کارآ تبدیل خواهند شد که به ‏طور متوسط، با کاهش حدود 25 درصدی ورودی‌ها، می‌توانند همان سطح خروجی را حفظ کنند.

چکیده [English]

This study is aimed at evaluating the efficiency of 23 greenhouses of red-leaf lettuce using the vertical hydroponic method based on the data envelopment Analysis (DEA) method in Alborz province of Iran. The assessment results indicated high profitability of red-leaf lettuce farming so that the production cost of each bush would be less than 15000 IRI rials while the sale price of each bush would be nearly 100000 IRI rials. In this study, four main inputs including workforce, secondary capital for conversion of the ordinary greenhouse into vertical hydroponic structure, fertilizer, and other costs were assumed as the model inputs and the net profit was considered as the output of the model that should be increased. Considering the technical efficiency and scale efficiency, the return-to-scale ratio of the efficient greenhouses was constant while most of the inefficient greenhouses had an increasing return-to-scale ratio. The efficiency analysis showed that the inefficient greenhouses were small greenhouses with an area smaller than 1000 square meters, which should increase their area and save on the consumption of the mentioned inputs in order to achieve higher efficiency and change into efficient units. Accordingly, with an average reduction of 25 percent in the inputs, these units can maintain their previous levels of output.
