چکیده

کاهش منابع آبی موجود در کشور از یک سو و افزایش تقاضای روزافزون تولید محصولات کشاورزی از سوی دیگر، لزوم توجه به مدیریت منابع آبی مورد استفاده در بخش کشاورزی را بیش از پیش افزایش داده است. مطالعه حاضر با هدف تدوین الگوی بهینه تولید محصولات زراعی در شرکت مزرعه نمونه گرگان به‌عنوان یکی از واحدهای پیشرو در بخش کشاورزی استان گلستان با تأکید بر افزایش کارایی مصرف آب طرح‌ریزی و اجرا شد. به این منظور، از آمار و اطلاعات دفتری این واحد کشاورزی در سال زراعی 95-1394 در قالب تدوین الگوی برنامه‌ریزی ریاضی چند معیاره استفاده گردید. نتایج نشان داد که با تدوین الگوی بهینه تولید محصولات زراعی در این واحد کشاورزی، کارایی مصرف آب به میزان 15 درصد، بازده ناخالص به میزان 9 درصد و خالص انرژی تولیدی به میزان 20 درصد افزایش می‌یابد. لذا، می‌توان گفت که در شرایط بهینه تولید محصولات زراعی در این واحد، آرمان‌های حداکثر بازده ناخالص و حداکثر خالص انرژی تولیدی به‌عنوان آرمان‌های اقتصادی در کنار آرمان افزایش کارایی مصرف آب به‌صورت هم‌زمان قابل‌دسترس خواهد بود. در پایان، با توجه به نتایج به‌دست‌آمده پیشنهاد شد که به‌منظور افزایش سودآوری در مزارع شرکت مزرعه نمونه گرگان هم‌زمان با تأکید بر افزایش کارایی مصرف آب، محصولات گندم، کلزا، پنبه، ذرت و یونجه ترکیب اصلی الگوی کشت محصولات زراعی در این واحد کشاورزی را تشکیل دهند.

چکیده [English]

The reduction of water resources used in the country, on the one hand, and the increasing demand for agricultural products on the other hand, has increased the need for attention to the management of water resources used in the agricultural sector.This study aimed at codification of optimal production patterning of agricultural crops in Gorgan Mazrae Nemoone Company as one of leading farms in the agriculture sector of Gorgan province was planned and implemented by emphasizing the increased water use efficiency. For this purpose, the statistical data and information of 2015-2016 crop year of the complex was used in the framework of multiple criteria decision making model. The results showed that in the optimum conditions for plant production in this agricultural farm, water use efficiency of 15%, gross margin of 9%, and net energy production by 20% would be increased. So, it can be said that ideals of maximum gross income and net maximum energy generated as the economic goals along with the ideal of increasing water efficiency will be available simultaneously. Finally, according to the results, it was suggested that in order to increase profitability in Mazrae Nemoone farms, while emphasizing increased water use efficiency, wheat, rapeseed, cotton, corn and alfalfa are the main components of the crop cultivation pattern.
