Tillage and fertilizer influenced soil characteristics through their effects on soil properties
which in turn affect crop performance. Field experiments were conducted during 2006 and …

In the first section of this chapter, several points related to the sole use of fertilizer are
addressed. Crops do respond to fertilizer, agronomically and socio‐economically …

Soil mechanical resistance directly affect seedling emergence and root growth. Tillage and
irrigation managements decrease soil mechanical resistance in soil depth and increase root …

There is scarcity of research information on tillage methods most suitable for yam (Dioscorea
rotundata) cultivation on Alfisols in Africa. Four tillage methods were compared as to their …

Research information on the effect of tillage systems on cocoyam (Xanthosoma sagittifolium
(L.) Schott) growth, nutrient status and yield is lacking in Africa. The effects of zero tillage …

Tillage and use of organic manure are important agronomic practices that sustain high crop
and soil productivity. Hence, a three-year (2007 to 2009) study was conducted to evaluate …

Intensive tractorised tillage practices especially in the tropical and subtropical climate
produces compaction in crop root zone (20 to 30 cm depth), degradation of soil quality, loss …

Soil erosion remains a major threat to sustainable use of soil and water resources, and often
leads to degradation of soil physical health. An erosion study was conducted on a slo** …

Cassava is traditionally grown on tilled soils. Interest in reduced-tillage systems is increasing
in the humid tropics due to erosion problems. A field study was conducted on a sandy clay …

The effects of no-tillage and alley crop** with Cassia spectabilis hedgerows on soil
properties and crop yields in a Typic Kandiudult of the humid forest zone of Central Africa …
