application of malmquist approach in analysis of total factor productivity growth of pulses in iran

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.
