Cassava-specific microregions in part of eastern Paraguay, a climatically homogeneous area, were defined on the basis of secondary data and systematic random sampling of agricultural settlements. It was found that production is concentrated in the departments of Caaguazu, Itapua, San Pedro, Parag...

Cassava micro-regions in part of eastern Paraguay : An explanation of their form and comparative study of cassava production within some of them
Cassava is a high-yielding crop, well adapted to areas of the tropics with low, uncertain rainfall and mean temperatures above 20 degrees Celsius.It has the ability to grow on very acid soils where few other crops will grow atall; however, highest yields are obtained under more fertile conditions...
In Uganda, highland banana yields (5-30 t ha-1yr-1) are low in comparison to potential yields (70 t ha-1yr-1) due to high pest and disease pressure, soil fertility decline, and poor management. Although it is generally accepted that soil exhaustion is a major cause of low and declining yields, th...

Public-private partnerships for sustainable supply of legume inputs in Northern Ghana
Smallholder farmers in the Guinea savanna practise cereal-legume intercropping to mitigate risks of crop failure in mono-cropping. The productivity of cereal-legume intercrops could be influenced by the spatial arrangement of the intercrops and the soil fertility status. Knowledge on the effect o...
