En la isla hay pocas areas sembradas con yuca, la cual se siembra en cultivo mixto (aroides/yuca/cocoa/cafe, aroides/batata/yuca o yuca/batata) o en monocultivo en el norte de Grande-Terre, en Marie-Ga...

Intensification and extensification of agriculture are eroding the integrity of tropical ecosystems. As global land comes under increasing anthropogenic management, considering the impacts of management practices on ecosystem services (ES) is essential. Cassava (Manihot esculenta Crantz) cultiva...

Phosphorus (P) is an essential element and its efficient use is of global importance. This study evaluated the effect of growing potato under legume intercrops on P uptake and use efficiency indices: P harvest index (PHI), P uptake efficiency (PuPE), P partial factor productivity (PPFP) and P par...

Adoption of soil carbon practices has the capability of increasing yield, thus improving income and food availability. This paper assessed the adoption of agricultural practices that enhance soil carbon. Data from 334 households were collected in the rural areas of Western Kenya using a multistag...
