"On-farm experiments were conducted in farmers’ fields at 12 different sites in the 2 districts of Moshi and Rombo in northern Tanzania during the 2000–01 cropping season to study the effects of (brady)rhizobial inoculation in combination with P supply on growth and grain yields of soybean and common bean, and to assess the economic returns of these different technologies to farmers. A low level of N was included as an indicator of endogenous soil N status.

"This paper investigates the effects of wheat genetic diversity and land degradation on risk and agricultural productivity in less favored production environments of a developing agricultural economy. Drawing production data from household survey conducted in the highlands of Ethiopia, we estimate a stochastic production function to evaluate the effects of variety richness, land degradation, and their interaction on the mean and the variance of wheat yield. Ethiopia is a centre of diversity for durum wheat and farmers manage complex variety mixtures on multiple plots.

Recent trends in agricultural growth and food security in Eastern and Central Africa (ECA) have been discouraging. With very low labor productivity, yields, and growth rates, agriculture is unable to keep up with population growth or achieve the type of pro-poor growth needed to reduce poverty dramatically.Yet agriculture accounts for about half of the region’s gross domestic product (GDP) and is the main source of livelihood for the majority of the population. Behind this gloomy picture, however, lies agriculture’s potential to be the engine for growth in ECA.
