“…The lack of response to planting method suggests that this factor plays a minor role in affecting leaves and stems at the end of the crop cycle. In any case, the values obtained in this experiment are consistent with the range indicated by Hauser et al [25], of 209 to 435 kg DM ha −1 among varieties.…”

“…Data on the production of cassava leaves and stems in response to planting methods and landraces are lacking in the literature [25], with leaves being picked up as vegetables continuously during the cropping season (and not only at the end as in our case) and stems not used at all for nutritional purposes but only as cutting sticks. As discussed before, most studies indeed concern the effect on root yield.…”

“…Indeed, cassava is also called in the Democratic Republic of the Congo (RDC) an "all-sufficient" crop because "roots constitute the bread, while leaves are the meat" [24]. Despite the fact that cassava leaves are not commonly consumed in all African countries, this is especially the case in the DRC [19,[25][26][27], where cassava leaves account for more than 60% of the entire vegetable consumption every year [26]. Indeed, being an extra-source of protein, vitamins, and minerals, cassava leaves may be considered a functional food to be introduced into traditional cassava root-based diets [5,[28][29][30][31][32][33], which are excessively rich in carbohydrates [34].…”

Sustainable Intensification of Cassava Production towards Food Security in the Lomami Province (DR Congo): Role of Planting Method and Landrace

Cassava is a mainstay crop for food security in Africa, its tubers being a large source of carbohydrates for the human diet. In some regions (e.g., the Democratic Republic of the Congo; DRC), leaves are also consumed as a source of proteins, vitamins, and minerals. Cassava adapts well to a range of soil-climate conditions and requires low inputs, yet yields are often unsatisfactory because of failures in disseminating improved genotypes and agricultural practices. The aim of this study was to test the effect of (i) seedbed preparation for planting cassava (i.e., flat, mounds, and ridges) and (ii) local landraces (i.e., Kakuanga, Kasongoy, Kasonie, Ndunda, and Ngoymuamba) on yield components and their nutritional quality in the Lomami province (DRC). In-depth measurements of yield components were performed, including the number of tubers and stems per plant, leaf biomass, stem biomass, root yield, and peeling yield. Tubers and leaves were also analyzed for chemical composition. Our results demonstrated that mound and ridge seedbed preparations may highly increase tuber yield (+32–68%) compared with flat. This is not the case for leaves and stems, which were not affected. The Ngoymuamba landrace showed a tuber yield about three times larger than Ndunda, which represented the common productivity values (5–8 Mg ha−1). No effect of seedbed preparation was observed and only minor differences between landraces were observed for the chemical composition of roots and leaves. We concluded that selecting the best-performing seedbed preparations × landraces could have a significant potential for achieving in a relatively short time the goal of “Zero Hunger” and improving the diet in the DRC.

“…For hand peeling, mainly in Africa, yield and productivity are also strongly related to the size and shape of the roots and the presence of constrictions. 72,73 The data collected by the RTBfoods project teams allowed visualization of the peeling yield and productivity as a function of root girth, root weight and root length (Fig. 2).…”

Roots, tubers and cooking bananas are bulky and highly perishable. In Africa, except for yams, their consumption is mainly after transport, peeling and cooking in the form of boiled pieces or dough, a few days after harvest. To stabilize, better preserve the products and, in the case of cassava, release toxic cyanogenic glucosides, a range of intermediate products have been developed, mainly for cassava, related to fermentation and drying after numerous processing operations. This review highlights, for the first time, the impact of genotypes on labour requirements, productivity, and the associated drudgery in processing operations primarily carried out by women processors. Peeling, soaking/grinding/fermentation, dewatering, sieving, and toasting steps were evaluated on a wide range of new hybrids and traditional landraces. The review highlights case studies of gari production from cassava. Results show that, depending on the genotypes used, women's required labour can be more than doubled and even the sum of the weights transported along the process can be up to four times higher for the same quantity of end product. Productivity and loads carried between each processing operation are highly influenced by root shape, ease of peeling, dry matter content and/or fiber content. Productivity and the often related experienced drudgery are key factors to be considered for a better acceptance of new genotypes by actors in the value‐addition chain, leading to enhanced adoption, and ultimately to improved livelihoods for women processors.This article is protected by copyright.
