Economic efficiency estimation of Rice crop in the Najaf Province in 2016 growing season

Abstract

This study aimed to estimate the economic efficiency of economic recourses that used in Rice production. Estimation was achieved by comparing the optimal quantities of resources and the used quantities. 30 farmers were involved in this questioner study in Najaf Province in 2016 growing season. The project depends on economic efficiency assessment and separating its components into technical and special efficiencies based on data envelop analysis. Optimal input sample under fixed and changed output of the capacity in counting the technical efficiency, and changed output of the capacity in counting special and expense efficiencies. Capacity average reaches 0.89, which led to a reverse relationship with family size and in line with relationship with the cultivation experience. The technical efficiency average was 0.90 which is an evidence on that these farmers able to obtain the same level of drop production by using 90% of production expenses with keeping the same production level. Expenses efficiency average was 0.67, which is an evidence on the reverse relationship between family size and positive with years of farming experience. Although the cultivated areas were increased the cultivating economic efficiency was decreased, which means crop production decreases that causes a rising in the economic inputs. This study recommends that using the production expenses according to the scientifically recommended quantity and ways, especially, seed quantity and fertilizer that are suitable for each crop to reach the optimal efficiency.
