چکیده

علی­رغم مطالعات صورت گرفته پیرامون کارآیی مصرف سوپر­جاذب­ها در بهبود شرایط فیزیکی خاک و نیز افزایش عملکرد و بهره­وری مصرف آب، مسائل اقتصادی کمتر مورد توجه پژوهشگران قرار گرفته است. بنابراین به منظور بررسی اثر تنش رطوبتی و سوپرجاذب استاکوزورب بر شاخص­های اقتصادی گندم، آزمایشی در سال زراعی 95-1394 به صورت فاکتوریل در قالب طرح بلوک­های کامل تصادفی در اراضی دانشکده کشاورزی دانشگاه تبریز در سه تکرار انجام شد. تیمارهای آزمایش شامل سه سطح 100، 70 و 50 درصد نیاز آبی گیاه (به­ترتیب FC، 0.7FC و 0.5FC) و مصرف سوپرجاذب استاکوزورب در سه سطح صفر، 50 و 100 کیلوگرم در هکتار (به ترتیب S0، S1 و S2) بود.نتایج حاصل از بررسی ­شاخص­های اقتصادی نشان داد که بیشترین درآمد خالص فروش گندم به تیمارهای S0,FC و S1,0.7FC اختصاص داشت. بیشترین نسبت درآمد ناخالص به هزینه تولید مربوط به تیمار S0,0.7FC بود که اختلاف معنی­داری با تیمار شاهد (S0,FC) در سطح احتمال 5 درصد داشت. بیشترین و کمترین میزان درآمد خالص به میزان آب آبیاری به ترتیب متعلق به تیمارهای  S1,0.7FCو S2,0.5FC بود که به میزان 2/44 و 7/11 درصد نسبت به تیمار شاهد (S0,FC) به ترتیب افزایش و کاهش داشتند. بنابراین در بهترین حالت (تیمار S1,0.7FC)، اثرات متقابل تنش و سوپرجاذب، درآمد ناخالص و درآمد خالص را نسبت به تیمار شاهد به ترتیب به میزان 2/12 و 1/1 درصد افزایش داد. در بین اثرات متقابل نیز تنها در شرایط تیمار S1,0.7FC به سبب افزایش عملکرد، افزایش سطح زیر کشت ناشی از کاهش مصرف آب و توجیه اقتصادی، مصرف سوپرجاذب توصیه می­شود.

چکیده [English]

Despite studies on the performance of superabsorbents in improving soil physical conditions, as well as increasing the yield and productivity of water consumption, economic issues have received less attention from researchers. Therefore in this study to investigate the effects of water stress and superabsorbent polymers on yield and yield components of wheat in 2015-2016 growing years, a factorial experiment was carried out in a randomized complete block design with three replications. Treatments consisted of combination of three levels of irrigation to supply 100, 70 and 50% crop water requirement (FC, 0.7FC, 0.5FC respectively) and three levels of superabsorbent (Stockosorb) with the amount of 0, 50 and 100 kg.ha-1 (S0, S1, S2 respectively). The results of economic indicators showed that the highest net income was allocated to S0,FC and S1,0.7FC treatments. The highest gross income to production cost ratio was allocated to the S0,0.7FC treatment, which had a significant difference with the control treatment (S0,FC) at the 5% level. The maximum (+44.2%) and minimum (-11.7%) of net income to irrigation water amount ratios were belong to S1,0.7FC and S2,0.5FC  treatments, as compared to control treatment (S0,FC), respectively. Therefore, in the best (S1,0.7FC treatment) condition, compared with control treatment, superabsorbent and water stress interaction effects increased gross income and net income equal to 12.2 and 1.1%, respectively. The investigating interaction effects of treatments showed that the superabsorbent application is recommended only in S1,0.7FC treatment condition due to increasing yield and cultivation area  (leading of reducing water consumption) and economic justification.
