Effect of farm size on efficiency of wheat production in Moretna-Jirru district in central Ethiopia

A study was conducted to examine the impact of farm size on efficiency of wheat production in Moretna-Jirru district in central Ethiopia. The growth of crop production by small-scale producers depends on the need to improve productivity of farmlands. It is evident that productivity growth may be achieved through either technological progress or efficiency improvement, such as improved farm education, to ensure that farmers use the existing resources more efficiently. The soil of the cultivated area is primarily characterized as vertisols, while others exist in small proportions. The area is well known primarily for the production of crops such as wheat followed by tef chickpea, lentil, grass pea and faba bean. A census carried out in March 1994 provided a sampling frame to randomly select the households who had official access to arabic land. Six input categories and eight inefficiency effects that may explain efficiency differentials among farm households were defined and used in the production function.
