Crop response to tillage practices in a Sahelian soil
1989
Klaij, M.C. | Hoogmoed, W.B.
Physical environment of the ICRISAT Sahelian Center, research on tillage and the use of alternative soil and crop-management practices to parry serious crop-establishment problems associated with wind-erodible sandy soils, crop water use and efficiency, and pearl millet yield are discussed. The results of 2 years of experimentation (one very dry, and one nearly normal year) show a positive interaction between presowing cultivation and other inputs such as fertilizers and crop residues for better crop establishment, yield, and water-use efficiency. The use of crop residue increased the organic matter content of the soil. Ridging was most promising as a wind-erosion control measure, required less energy than did plough, and could be performed efficiently using animal power
