Although cassava -a tropical crop- is regarded as a staple food crop for millions of people worldwide, it is still considered as a subsistence crop and seldom receives adequate crop management. Average yields are less than 8 t/ha. Colombia`s North Coast, where large areas of sandy soils are plant...

Tropical soils are generally low in fertility, physically fragile and easily eroded when cleared of natural cover. Cultivation is carried out in the tropics purely for weed control, but this leads to accelerated soil erosion, as cultivated soil) has no protection. Gully erosion can be minimized b...


Couper, D.C.[No-till farming in the humid and subhumid tropics of Africa]No-till farming in the humid and subhumid tropics of Africa

The goal of tillage is to provide a suitable environment for seed germination and root growth, and to control weeds. Research on tropical soils has shown that tillage is only useful to control weeds. In general, tillage damages the soil. Chemical weed control is preferable. In many African countr...

Wheat is an important food and income source and estimated demand for wheat in the developing world is projected to increase substantially. The objectives of this study were to gain insight into (i) the effect of tillage straw system on yield and yield components (number of grains per m2 and thou...

Long term use of Maresha plow, a conventional plow pulled by oxen, has resulted in the formation of a restrictive layer thereby limiting water movement and aeration as well as root zone penetration in the soil profile. Several studies have shown that improved tillage practices can positively affe...
