On-station and on-farm studies were carried out in 2008 during the long rains (March – May), in Taita region, Kenya, to assess the effect of various soil fertility regimens on bean stem maggot (BSM) (Ophiomyia spp.) and black bean aphid (BBA) (Aphis fabae) incidences. These studies aimed at gathe...

We detail the impact of abandoned traditional settlements (or bomas) on plant and nutrient succession in the Amboseli ecosystem, southern Kenya, over the course of a century. Plant and soil data were sampled on and around abandoned settlements. The term, ‘onsite’, refers to the area within the pe...

IITA developed alley cropping (also called hedgerow intercropping by ICRAF) in the mid 1970s to alleviate the problems of reduced soil fertility, reduced yields and soil erosion that were associated with population growth and reduced fallow periods. In the early 1980s this technology was adapted ...

In Cambodia, cassava is mostly grown with little or no fertilizer inputs, but the
magnitudes of nutrient balances are not known. This study was conducted to assess
nutrient balances for cassava cultivation in Kampong Cham province in Northeast
Cambodia. Forty five households in four cassava pr...
