Agronomic and economic benefits of coffee banana intercropping in Ugandas smallholder farming systems by Asten, Piet J.A. van, Wairegi, L.W.I., Mukasa, D., Uringi, N.O.

“…In Robusta growing region, banana yields were significantly lower (P ⩽ 0.05) in intercrops (8.89 t ha−1 year−1) compared with mono-crops (15.04 t ha−1 year−1). Marginal rate of returns of adding banana to mono-cropped coffee was 911% and 200% in Arabica and Robusta growing regions, respectively. …”

Factors driving fertilizer adoption in banana (Musa spp.) systems in Uganda by Asten, Piet J.A. van, Wairegi, L.W.I., Bagamba, F., Drew, C.

“…Fertilizer use was highly profitable at sites close to Kampala market but not at sites far away (>250 km). The marginal rates of return exceeded 575% in Wakiso district (Central Uganda) but only averaged 10% in Bushenyi (Southwest Uganda). …”

Characterization of an 18,166 EST dataset for cassava (Manihot esculenta Crantz) enriched for drought responsive genes by Lokko, Y., Anderson, J., Rudd, S., Raji, A., Horvath, D., Mikel, M.A., Kim, R., Liu, L., Hernández, A., Dixon, A., Ingelbrecht, I.L.

“…Cassava has a high growth rate under optimal conditions but also performs well in drought-prone areas and on marginal soils. To increase the tools for understanding and manipulating drought tolerance in cassava, we generated expressed sequence tags (ESTs) from normalized cDNA libraries prepared from dehydration stressed and control well-watered tissues. …”

Effect of chicken manure application on cassava biomass and root yields in two agro-ecologies of Zambia by Biratu, G.K., Elias, E., Ntawuruhunga, Pheneas, Nhamo, N.

“…This treatment showed 71% and 81% fresh root yield advantage over the control at Mansa and Kabangwe, respectively. While the marginal rate of return (MRR) was negative for the mineral fertilizer, it was positive for all the chicken manure treatments with the maximum (315%) achieved from the application of 4.2 ton/ha. …”

Why do forest products become less available?: A pan-tropical comparison of drivers of forest-resource degradation by Hermans-Neumann, Kathleen, Gerstner, K., Geijzendorffer, I.R., Herold, Martin, Seppelt, Ralf, Wunder, Sven

“…Our results thus suggest that perceived resource declines have only exceptionally triggered adaptations in local resource-use and management patterns that would effectively deal with scarcity. Hence, at the margin this supports neo-Malthusian over neo-Boserupian explanations of local resource-use dynamics.…”
