A substantial impact on Africa agriculture can be made through research on crop improvement for the extensive inland valley agro-ecosystems (IVS) extending from the humid forest to the savanna zones in sub saharan Africa. Systematic surveys of farmers have shown that cassava is a favoured upland ...

The leaf is the site of photosynthetic activities and crop productivity is controlled by the sizes and efficiency of leaves. Leaf development in cassava can be dependent on genetic makeup of the plant and it is sensitive to temperature. The aim of this study was to quantify the relationships betw...

Water logging is a potential abiotic stress problem in the warm tropical potato growing areas, particularly in the lowland rice-based cropping systems. A field experiment was conducted in San Ramon, Peru during the rainy season to evaluate the effects of water logging on 12 clones (8 lowland trop...
