The aim of this paper is to determine the characteristics and preferences of cocoa farmers in the humid forest zone of Cameroon who are actively diversifying their cocoa agroforests by planting Dacryodes edulis. A survey conducted amongst 300 farmers revealed that about 80 percent of them grow Da...

In order to determine the improved soybean varieties that if recommended to the farmers would have a high probability of adoption, a farmer participatory approach was used to evaluate 12 soybean varieties at full podding in five locations (Oyani, Riana, Kasewe, Akiites, and Mabole) in western Ken...

Crop promotion is critical for market creation and rural growth in Africa. How to achieve this for crops, other than major staples (e.g., maize) and traditional export crops (e.g., tea), remains a problem since most African countries tend to focus policy attention to major staples and traditional...

Slash-and-burn agriculture continues to expand in many parts of the forest zone of Cameroon. One alternative land use to slash-and-burn system is alley farming. This paper quantifies, using an econometric model, the factors determining farmers’ adoption and use of alley farming variants in southw...

Low use of chemical inputs has been cited as a major factor limiting productivity growth of agriculture in most of sub-Saharan Africa. A wide range of variables influence adoption of such input. It is important to understand the role of these factors to ensure the development and implementation o...

Alley farming is an improved fallow technology developed at the International Institute of Tropical Agriculture (IITA) as a sustainable alternative to slash-and-burn systems practiced by farmers in sub-Saharan Africa. Constraints to the use of the technology have been examined, but studies are li...

In the semiarid region of West and Central Africa, farmers traditionally cultivate different cowpea varieties for grain and fodder. However, the grain yield potential and the availability of good quality fodder is limited by several factors: insects, pests and diseases, low and erratic rainfall, ...
