The determinants of cereal crop productivity of the peasant farm sector in Ethiopia, 1981–87

This paper employs a Cobb-Douglas type production function to estimate the impacts of various farm inputs on cereal crop production of the peasant farm sector in Ethiopia. The production function is estimated for the major food crops, teff, wheat, maize, barley and sorghum, using seemingly unrelated regression estimation (SURE). On average, about 90 per cent of crop output is explained by the two major traditional inputs, land and labour. Less than 10 per cent of output is explained by chemical fertilizers. The impact of chemical fertilizers is small but statistically significant. Rainfall has an important impact on cereal production. Stagnant and declining food production is due to poor factor productivity, which is mainly explained by population pressure, poor farming practice and vulnerability to droughts.
