Maize (Zea mays L.) and bean (Phaseolus vulgaris L.) are commonly grown in association in eastern and southern Africa. Results from 64-fertilizer response trials conducted in Kenya were used to study the relationship between maize monoculture response to fertilizer nitrogen and phosphorus and the...
The application of silicon (Si) fertilizers reduces the severity of blast, caused by Magnaporthe grisea, in irrigated and upland rice; however, little research has been conducted to examine the epidemiological and etiological components of this reduction. Four cultivars of rice with differential ...
Crop response, tree biomass production and changes in soil fertility characteristics were monitored in a long-term (1986–2002) alley-cropping trial in Ibadan, Nigeria. The systems included two alley cropping systems with Leucaena leucocephala and Senna siamea on the one hand and a control (no-tre...

More than sixty and over a third of the total farm households in the coun...
The effect of soil fertility on the response of field beans (Phaseolus vulgaris L.) to inoculation with Rhizobium leguminosarum bv. phaseoli was investigated at five sites in northern and central Malawi. A split-plot design consisting of (a) un-inoculated plants, (b) inoculated plants and (c) N-f...
