Technical Efficiency of Sorghum Production in the Mechanized and Traditional Rain-fed Agricultural Sub-Sectors in South Kordofan State, Sudan
This study estimated and evaluated the technical efficiency of the mechanized and traditional rain-fed farming systems in South Kordofan State, Sudan. Primary data for the study were obtained using structured questionnaire administered to 200 randomly sampled farmers in the two farming systems from four designated locations in the study area. This was done byusing a stochastic frontier production function. The results showed that the coefficients of labor, sex, age, distance and type of finance were found all positively and significantly, while farm size, quality of seeds, labor, family size, occupation and extension services were found statistically significant at 1% and 5% level of probability, respectively. All the farmers were producing below the maximum efficiency frontier. The farmer’s technical efficiency indices varied between 0.10 and 1.0 in the mechanized and traditional farming system, respectively. Also the mean of the farmer’s technical efficiency was 0.69 in the mechanized system compared to 0.66 in the traditional farming system. It is also indicates that farmers can increase production of sorghum by 31% and 34% in the mechanized and traditional farming system, respectively. This means that there is a room for farmers to increase the technical efficiencies of production of these crops up to the optimum level (100%). The strengthening of the agricultural extension services in the study area is needed. Facilitating the financing process through micro-finance and repayment in kind is essential.
