چکیده

ارتقای بهره‌وری آب در تولید مواد غذایی از مسائل اساسی در کشورهای مختلف جهان و به­ویژه کشورهای کم‌آب نظیر ایران است. در شرایط حاضر اندازه‌گیری و تحلیل شاخص‌های بهره‌وری نهاده کمیاب آب در بخش کشاورزی در ایران به علت محدودیت کمی و کیفی این ماده ارزشمند از جایگاه خاصی برخوردار است. هدف از پژوهش حاضر اندازه­گیری و مقایسه بهره­وری فیزیکی و اقتصادی مصرف آب آبیاری در دو سیستم آبیاری سنتی و مدرن برای محصولات عمده زراعی شامل گندم، جو، کلزا، یونجه و ذرت علوفه­ای در شهرستان شهریار می‌باشد. در این پژوهش، برای محاسبه بهره­وری آب کشاورزی از شاخص عملکرد به ازای واحد حجم آب (CPD) شاخص درآمد به ازای واحد حجم آب (BPD) و شاخص بازده خالص به ازای واحد حجم آب (NBPD) استفاده‌شد. بر اساس نتایج تحقیق، در هر دو سیستم آبیاری، اولویت کشت محصولات تا رتبه دوم بر اساس شاخص CPD به­ترتیب ذرت علوفه­ای و یونجه می‌باشد. همچنین بر اساس دو شاخص BPD و NBPD در سیستم آبیاری مدرن، اولویت کشت محصولات به ترتیب به محصولات کلزا و گندم و در سیستم آبیاری سنتی محصولات کلزا و یونجه می‌باشد.

چکیده [English]

Promoting water productivity in food production is one of the main issues in different countries of the world, especially in low-water countries like Iran. In the present situation, measurement and analysis of productivity indices of scarce water input in agricultural sector in Iran is of special importance due to the quantitative and qualitative limitation of this valuable material. Therefore, the purpose of the present study is to measure and compare the physical and economic productivity of irrigation water use in two traditional and modern irrigation systems for major crops (Wheat, Barley, Rapeseed, Alfalfa and Forage Corn) in Shahriar. In this study, the CPD, BPD and NBPD were used to calculate of agricultural water productivity. According to the results of the study, in both irrigation systems, the priority of crop cultivation to the second rank is based on CPD index Forage Corn and Alfalfa, respectively. Also based on both BPD and NBPD indices in modern irrigation system are Rapeseed and Wheat respectively and in traditional irrigation system Rapeseed and Alfalfa, respectively.
