Special issue : Part II

Description :
For small farmers in the Bolivian highlands, wheat crop production is limited by moisture stress and soil erosion. A. discusses research in two Bolivian departments, Chuquisaca and Cochabamba, conducted to increase water-use efficiency and productivity. Crop residue increased water infiltration and yields in the Cochabamba high valley. However, in Chuquisaca the effects of ground cover were small or negative. Seeders are discussed. - (SLD)
