The phenology of East African highland banana (Musa acuminata AAA-EA, hereafter referred to as ‘high-land banana’) is poorly understood. We tested three hypotheses: (1) the physiological age at floweringis independent of site effects, (2) there is no difference in threshold size at flowering betw...

Approaches that aim to identify and prioritize locally appropriate climate smart agriculture (CSA) technologies will need to address the context-specific multi-dimensional complexity in agricultural systems. The climate smart agriculture rapid appraisal (CSA-RA) is a mixed method approach that dr...

Low and declining soil fertility has been recognized for a long time as a major impediment to intensifying agriculture in sub-Saharan Africa (SSA). Consequently, from the inception of international agricultural research, centres operating in SSA have had a research programme focusing on soil and ...

tCoffee is Uganda’s biggest export commodity, produced mainly by an estimated one million smallholderfarmers (<2.5 ha). Arabica (Coffea arabica L.) and Robusta (Coffea canephora Pierre ex Froehn.) are thetwo coffee species grown. Robusta is dominantly cultivated at lower elevations (<1400 m) such...

Coffee is a major cash crop in Uganda accounting for about 20 30% of foreign exchange earnings. Smallholder farmers whose average farm sizes range from 0.5 to 2.5 ha produce 90% of Uganda s coffee. The livelihoods of these smallholder coffee farmers are very vulnerable and studies have shown that...

Root colonization, soil population density and diversity of arbuscular mycorrhizal (AM) fungi were assessed in 188 banana fields in contrasting soil types across five eco-regions in Rwanda (Butare–Gitarama, Gashonga, Bugarama, Kibungo, Ruhengeri). Root colonization was observed in all banana plan...

This study aims to explain effects of soil textural class, topography, land use, and land use history on soil greenhouse gas (GHG) fluxes in the Lake Victoria region. We measured GHG fluxes from intact soil cores collected in Rakai, Uganda, an area characterized by low‐input smallholder (<2 ha) f...

Poor soil fertility is a constraint to coffee production. Targeting fertiliser recommendations to nutrient deficiencies can contribute to improved crop response to fertiliser. This study aimed to derive and compare the Compositional Nutrient Diagnosis (CND) and Diagnosis and Recommendation Integr...
