In Kenya the belowground biodiversity project was implemented in Embu and Taita which are biodiversity hotspots. The objective of the paper is to present and analyze farmers’ knowledge, attitudes and practices at different timelines of the project, as well as identify factors limiting adoption of the best bet technologies. In early 1960’s when natural forest was cleared for farming activities no farm inputs were introduced in food crops until after 10 years.

Factors influencing the incidence of the black bean aphid, Aphis fabae scop., on common beans intercropped with maize

The incidence of the black bean aphid, Aphis fabae check for this species in other resources scop. (Homoptera: Aphididae), and its colonization of common beans (phaseolus vulgaris L.) grown as sole crop and as intercrops with maize ( Zea mays check for this species in other resources L.) of varying growth stages was evaluated in the field and glasshouse. Modification of bean micro-climate and its effects on A. fabae, and the species range and abundance of coccinellid predators (Coleoptera: Coccinellidae) of the aphid were also assessed. Results showed that A.

Livestock manure is an important source of nutrients for crop production in semi-arid West Africa. An assessment of the potential of manure to sustain crop production calls for an estimation of the amounts of manure that could be produced and captured and the feed resources required to maintain livestock used for manuring. This paper presents estimates of the amounts of manure produced by cattle, goats and sheep fed ad libitum under confinement. A model is presented to predict the yearly faecal output by grazing ruminants under fluctuating feed supplies.
