| This study employed a Tobit model to examine factors that influence the adoption and intensity of utilisation of improved maize varieties in the West Shoa Zone in the central highlands of Ethiopia. The estimated results indicate that level of education, household labour, farm size, extension services, farm income, and timely availability of improved maize seeds significantly influence the adoption and intensity of use of improved maize. It also showed that the impact of off-farm income and age of the household head on adoption and intensity of use of improved maize seed was insignificant. |

| This paper applied an extended total factor productivity analysis to compare the resource use efficiency of alternative cropping systems in eastern Ethiopia. The results indicated considerable variation in resource use efficiency among cropping systems. Intercropping of sorghum with pulses in the dry lands and intercropping of maize with potatoes in the wet highlands turned out to be the most efficient practices. The results have important implications for research and extension services not only for promoting innovative cropping systems but also for integrating currently available improved technologies into the complex farming systems that are dictated by agro-climatic and demographic factors. |

| This paper employed a robust stochastic efficiency decomposition technique that accounts for scale effects to derive the technical, allocative, and overall productive efficiency of two samples of farmers, participants and non-participants in the New Extension Program (NEP), in two agro-climatic zones in eastern Ethiopia. Using data for the 2001/2002 agricultural year, we find that both groups of farmers in the two zones have considerable overall productive inefficiencies. In the wet highlands, although the participants in NEP used a superior technology and have higher technical efficiencies, their allocative efficiencies turned out to be lower than the non-participant farmers, relative to their respective technologies. However, both groups exhibit similar... |

| This paper assesses the potential economic impacts of balanced nutrient management systems technology options: BNMS-manure, which combines inorganic fertilizer and organic manure, and BNMS-rotation, which is maize–soybean rotation, in maize-based systems in the northern Guinea savanna areas of Nigeria, Ghana, Togo and Benin. The economic surplus analysis suggested that BNMS-manure research and extension could achieve returns ranging from 17 to 25% and a maximum adoption of 24 to 48%, for the conservative and base scenario respectively; and that BNMS-rotation research and extension could achieve returns ranging from 35 to 43% and a maximum adoption of 20 to 40%, for the conservative and base scenario respectively. Our results were consistent with earlier... |
