The major constraints to stable production of cassava in Africa are diseases, insects, mites, weeds, soil and agronomic limitations and socio-economic factors. Of the economic diseases, African cassava mosaic, bacterial blight, and anthracnose are the most important. The green spider mite and cas...

This paper evaluates the impact of a cassava research-for-development program on farm level outcomes.The program was implemented in the Democratic Republic of Congo from 2001 to 2009. We apply pro-pensity score matching, Rosenbaum bounds on treatment effects, Altonji et al. method of selection on...

Does a cassava researchfordevelopment program have impact at the farm level? Evidence from the Democratic Republic of Congo
A better understanding of the factors that contribute to low cassava yields in farmers’ fields is required to guide the formulation of cassava intensification programs. Using a boundary line approach, we analysed the contribution of soil fertility, pest and disease infestation and farmers’ cultiv...

Cassava yield loss in farmer fields was mainly caused by low soil fertility and suboptimal management practices in two provinces of the Democratic Republic of Congo
Purpose – Cassava production surged noticeably in Southeastern Africa beginning in the 1990s. The purpose of this paper is to examine the commercial responses and food security consequences of cassava production growth in the region.
Design/methodology/approach – The paper incorporates a mix of q...

In the dry season 1997-1998, unusual damage was observed on cassava at M'vuazi INERA research station (Lat. 5°25'S, Long. 14°54'E, Alt. 465m asl) in the Bas-Congo province, DR Congo (DRC). The damage was first attributed to cassava green
mite (CGM), but subsequent observations and literature sear...

An experiment was conducted to evaluate the feeding and economic value of cassava starch by-products as source of energy in diets for growing fattening pigs. Cassava starch by-products were incorporated in the diets at 0 (treatment 1, control), 10 (treatment 2), 20 (treatment 3) and 30% (treatmen...

Starch separated from eleven sweet potato varieties was subjected to heat moisture treatment (HMT) at 30% moisture and 110°C for 3 hours. Following HMT, there were no significant changes in physicochemical properties of the starches. This was attributed to limited moisture content (30%) to influe...

A cassava pulverizer was fabricated and tested for starch extraction from cassava at Masinda Cassava Starch Cooperative Society in Malawi. When tested, the pulverizer increased the starch extraction percentage from cassava by 16.9% as compared to grating only and it showed that these results were...
