چکیده

در این مطالعه رشد بهره‌وری کل عوامل تولید حبوبات ایران شامل نخود آبی، نخود دیم، عدس آبی، عدس دیم و لوبیا آبی با استفاده از روش ناپارامتریک مالم‌کوئیست طی سال‌های زراعی 1387-1368 مورد بررسی و تجزیه و تحلیل قرار گرفته است. دراین‌راستا، مقادیر مصرف نهاده‌های بذر، کود حیوانی، کود شیمیایی، علف‌کش، سم، نیروی کار، آب مصرفی و سطح زیر کشت و مقدار ستانده حبوبات ایران مدنظر قرار گرفت. نتایج نشان داد که تولید نخود آبی نسبت به سایر حبوبات مورد بررسی از کمترین رشد بهره‌وری در دوره زمانی مورد مطالعه برخوردار می‌باشد. همچنین محصولات عدس آبی، عدس دیم و نخود آبی با توجه به تغییرات تکنولوژی و کارایی دارای رشد منفی در بهره‌وری کل عوامل تولید می‌باشند و محصولات لوبیا آبی و نخود دیم دارای رشد مثبت در بهره‌وری کل عوامل تولید طی سال‌های مورد بررسی بوده است. بررسی تغییرات سالانه بهره‌وری حبوبات و اجزای آن نشان می‌دهد بالاترین رشد بهره‌وری در سال زراعی 80-1379 برابر با 85 درصد و بیشترین رشد منفی در سال زراعی 79-1378 برابر با 9/36 درصد می‌باشد.

چکیده [English]

In this study, total factor productivity growth of Iran’s pulses (including irrigated pea, dry pea, irrigated lentil, dry lentil, irrigated soybean, dry soybean and irrigated bean) during of farming years 1989-1990 though 2007-2008 had been analyzed, using Nonparametric Malmquist approach. So, amounts of inputs usages include seeds, fertilizers, dung, poison, herbicide, labor, water and acreages and also, output quantity include pulses production had been considered. Results showed chickpeas production minimum TFP growth in mentioned time period. Products like irrigated and dry lentil, irrigated pea have negative growth on the basis of technology variation and efficiency and products like irrigated bean and dry land pea have positive growth in total factor productivity during the studied years. Examining the annual variation and its components show that the highest growth in 2000-2001 was 85 percent and the highest negative growth in 1999-2000 was 36.9 percent.
