Wetlands are important providers of ecosystem services and key regulators of climate change. They positively contribute to global warming through their greenhouse gas emissions, and negatively through the accumulation of organic material in histosols, particularly in peatlands. Our understanding ...

Cassava, one of the world's major food crops is grown throughout the tropical regions of the world. Cassava originated in the neotropics; it was introduced into West Africa from Brazil by slave traders in the 1500's, and taken to Asia during the 17th century. Consequently the greatest diversity o...

The major subsistence food systems of the world that feed resource?poor populations are identified and their capacity to supply essential nutrients in reasonable balance to the people dependent on them has been considered for some of these with a view to overcoming their nutrient limitations in s...

A total of 93 isolates of Xanthomonas campestris pv. phaseoli was collected from five countries over a wide range of altitude (500 2320 m above sea level) in eastern Africa. Collections were made from a range of cultivars of the common bean (Phaseolus vulgaris), including known sources of resista...

Seed analysis can indicate differences in micronutrient availability between soils. Comparison of Phaseolus vulgaris L. with published analytical data indicated that the micronutrients most limiting for N2-fixation and growth in parts of East and soLithem Africa were Mo and Cu. Significant differ...

Low phosphorus (P) supply is a major limitation to pasture establishment and production in highly weathered acid soils. Previous research showed that the forage legume, Arachis pintoi, was more efficient in acquiring P from infertile acid soils than the forage grass, Brachiaria dictyoneura. The m...

A wide range of fungi, two bacteria and several viruses and nematodes have been recorded throughout the tropics on a group of Cassia species defined as taxonomically and geographically related to Cassia rotundifolia. Although limited information was found on the relative importance of these patho...
