Growth and N uptake in pot-grown maize, beans, and cassava were evaluated under 2 levels of soil N at CIAT-Palmira (Colombia). The lower amount of the element reduced its uptake by the 3 species, resulting in lower tissue concn., especially in the leaves. Under low N, DM accumulation was also red...

The gene pools for breeding cassava (Manihot esculenta Crantz) in Africa currently contain only a fraction of the existing genetic variation found in Latin America where the crop originates. Our research aimed to broaden the genetic base in Africa by introducing Latin American (LA) germplasm. The...

Climatic and edaphic factors are important determinants of the growth and yield potential of an ecological environment. Among other cultural practices, planting methods play a very vital role in the performance of a crop. The effects of planting methods and soil moisture on cassava (Manihot escul...
