The grain yields in the no-tillage plots were equivalent to those of conventionally plowed treatments. No-tillage treatments had higher organic matter content and, by controlling soil erosion, the silt and clay content than the plowed plots. The water holding capacity and moisture release charact...

The objective of this experiment was to evaluate the effects of growing a deep-rooting perennial on the root system development of a subsequent crop with low root penetrating ability. These effects were measured on a gravelly Alfisol with a compacted subsoil horizon for three tillage methods (zer...

The effect of no-tillage and mulch on soil properties and tuber yield of cassava was studied over a five year period on an infertile, acid Ultisol in south-eastern Nigeria. Mulch was applied at a rate of 12 t ha−1 as a split application once at planting and once six months after planting. No chem...
