The decline of cooking banana production in parts of East Africa has been associated with a loss of soil fertility and increased pest pressure. Previous work indicated that the use of mineral fertilizers at recommended rates is not financially viable on plantations where pest pressure is high. Th...

Effects of mulch and mineral fertilizer on crop, weevil and soil quality parameters in highland banana
Low soil fertility and pest pressure are two causes of the decline in banana (Musa AAA) production in central Uganda. Foliar analysis by the Diagnosis and Recommendation Integrated System (DRIS) pinpoints K and Mg as the most limiting nutrients. This study tested the effects of K and Mg additions...

This paper reports on a Participatory Learning and Action Research (PLAR) process that was initiated in three villages in eastern Uganda in September 1999 to enable small-scale farmers to reverse nutrient depletion of their soils profitably by increasing their capacity to develop, adapt and use i...

On farm testing of integrated nutrient management strategies in Eastern Uganda
Major constraints to banana (Musa spp., genome group AAA) production, a dietary staple for over 70 million people in sub-Saharan Africa, are pest infestations, poor nutrition and inadequate water. Although mulch can improve soil water and nutrient status, many farmers believe it also promotes the...

Phosphorus (P) is required to improve soil fertility for food and feed produciton in sub-Saharan Africa, but the high cost of conventional, water-soluble P fertilizers limits their use by resource-poor farmers. Rockphosphates are a low-cost alternative. The effectiveness, in terms of seed product...

Agronomic evaluation of unacidulated and partially acidulated Chilembwe rockphosphates for clover seed production
East African highland cooking bananas (Musa spp., AAA) are one of the most important staples in the Great Lakes region of Africa. It has been hypothesized that land use intensification within the region has led to decline in soil fertility, increased pest pressure, and decline in production. To d...

This paper reports results from a 6-year long-term fertilizer X banana weevil trial for highland banana in Mbarara, Uganda. The objective of the study was to quantify the effect of mineral fertiliser (100 kg N, 50 kg P, and 100 kg K ha -1 yr-1) on crop and economic performance and weevil pest sta...

Banana (Musa AAA) and plantain (Musa AAB) are important dietary staples for over 70 million people in sub-Saharan Africa. Banana weevil (Cosmopolites sordidus) and nematodes (Radopholus similis, Helicotylenchus multicinctus) are often the largest constraints to production. Leguminous crops in the...

Resource flow models are useful tools that assist farmers in analysing their soil fertility management strategies and in planning, experimenting and adapting ways to improve the use of scarce local resources. Resource flows and farm nutrient balance studies were carried out in eastern Uganda to a...

The majority of soils in Africa are P-deficient, but the high cost of conventional, water-soluble P fertilisers limits their use by resource-poor farmers. Rockphosphates are a low-cost alternative. The relative agronomic effectiveness of unacidulated (RP), 25 percent partially acidulated (PARP25)...
