BACKGROUND In southern Africa, conservation agriculture (CA) has received a lot of research and promotional support from various organizations in the past decades. Conservation agriculture is largely promoted as one of the few win–win technologies affordable to farmers, in the sense that potentia...

We analyse yield effects of tissue culture (TC) banana technology in the Kenyan small farm sector, using recent survey data and an endogenous switching regression approach. TC banana plantlets, which are free from pests and diseases, have been introduced in East Africa since the late 1990s. Altho...

Potatoes have become increasingly popular amongst Chinese consumers, and the water saving and storage capacity of the crop have made it a target of Government promotions. Potato production is a means of generating income as well as improving food and water security. Getting the right varieties to...

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...

Impact studies assuming exogenous technology adoption are bound to overstate or understate the true impact of improved agricultural technologies, especially in situations where agricultural technologies are targeted to, or adopted by, a certain group of farmers. This paper examined the impact of ...

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, ...

Population pressure in the southern provinces of Benin has forced farmers to shorten or abandon the traditional bush fallow system. As a consequence, severe soil degradation and weed infestation constitute the most serious constraints to agricultural productivity. Mucuna fallow is one of the most...

Purpose This impact assessment provides empirical evidence from household producer surveys to test the assumptions surrounding the contribution of participatory varietal selection (PVS) activities on seed sector development. The purpose of this paper is to focus on household access and adoption ...
