“…Due to the large number and diversity of cowpea diseases and pests, an integrated set of management at different stages of cowpea growth was recommended [29,30]. Dissemination of chemical free hermetic bags for cowpea storage has also improved cowpea storage in most parts of Africa, but due to several alternative hermetic bags, testing and making the best storage available to producers may be essential [31]. To increase productivity and to reduce post-harvest losses in storage, training, awareness, and financial support may be required.…”

Socio-economic constraints like gender, education, age, and income significantly affect the adoption of improved agricultural technologies. The objective of this study was to determine socio-economic factors that affect the adoption of improved cowpea varieties in the Senegalese peanut basin. The study was conducted in three (Bambey, Kebemer, and Kaffrine) of six regions of the peanut basin based on regional importance of cowpea production and rainfall gradient. In each study region, ten villages were selected, and random sampling was used to select eight heads of agricultural households within each village. The questionnaires were administered to 240 randomly selected farmers across the three study regions, 7 communes, and 30 villages. Results showed most heads of households were middle-aged (52–54 years old), married (95–100%), illiterate (84%), and men (95–100%). Households were mostly agriculture dependent (87%), low literacy rates (26% least primary school), and large family sizes (average of 15 members). The median cowpea yields across the study area varied from 35–100 kg ha−1, well below the ~300–400 kg ha−1 average yields reported for Senegal and Sub-Saharan Africa. The majority of farmers (67%) in the study regions did not use improved varieties, and the main reasons were low seed availability (78.8%) and limited access to technical knowledge and information (76.3%), but only 5.8% indicated seed price as a barrier to improved variety adoption. Major uses of cowpea in the study area were for marketing, livestock feed, and human consumption. In Kaffrine, fodder production was the major (85%) criterion for cowpea variety selection, whereas in the north (Bambey and Kebemer), taste, maturity date, and grain yield were major selection criteria. Factors that had positive effect on the likelihood of using improved cowpea varieties include; access to extension services, membership in farmers’ organization, cowpea being the main crop of production, organic farming, market, and livestock-oriented production systems, access to farmland and credit, dependence on agriculture as the main source of household income, and education of head of household. We conclude that there is a critical need for training, access to improved seeds, awareness, and financial support to producers to increase the adoption of new improved cowpea varieties, yields, profitability, and nutritional security among smallholder farmers in the Senegalese peanut basin.

“…However, a significant proportion of these crops, especially cowpea are lost during storage. Cowpea farmers in the West Africa lose a significant portion of their crop during storage due to insects (cowpea weevil) [9]. The main purpose of storage is to even out fluctuations in market supply by taking the produce off the market in surplus seasons, and releasing it back into the market in lean seasons.…”

This research was carried out to compare cowpea storage characteristics using different storage medium, under different weather conditions. Several technologies reputedly attribute losses of stored cowpea grain to bruchid beetles. Comparison of these different postharvest storage methods can provide the basis for deciding which performs best in terms of weight loss, pest infestation and nutritive losses. Proximate analysis was carried out before, during and after storage with two month intervals, over four months of storage in three storage media: a seed gene bank, modified anthill rhombus, and a covered container (the control). Temperature, humidity, and weight values (for moisture content analysis) were taken during the storage period. Results showed that the cowpea seed sample, stored in the AC section of the seed gene bank, proved to be more tolerant to pest infestation compared to seed samples, stored in the Modified anthill rhombus, and seed samples, stored under ambient conditions. The cowpea seeds weight recorded reduction after infestation, which also was significant when compared to the non-infested seeds in the seed gene bank. Proximate analysis of cowpea seeds after infestation showed a decrease in the value of carbohydrate content and protein, while crude fibre, moisture, fat and total ash recorded increased. Further research should be carried out on cowpea storage under different weather conditions, with and without insecticide, and using more media such as jute bags, etc. There should also be an extension of the storage period more than the four months

Postharvest management is critical to attaining household food, nutrition, and income security. Hermetic grain storage bags offer an effective pesticide‐free way to protect stored grain against fungal and insect infestation. We evaluated articles indexed in the Web of Science that included experiments comparing the storage efficacy of conventional and hermetic storage bags based on grain germination rate, insect infestation, physical damage, mycotoxin contamination, and changes in weight and moisture content. Compared with grain stored in hermetic bags, grain stored in conventional bags lost 3.6‐fold more seed viability, contained 42‐fold more insects, had 11‐fold more physical damage, and lost 23‐fold more grain weight, while grain moisture levels were similar for both hermetic and conventional storage bags. Mycotoxin contamination levels were not as frequently assessed. Levels could be low in grain stored in both types of bags, or levels could be low in hermetic bags and significantly higher in conventional bags. The improved properties of grain stored in hermetic bags can increase food security and household income by providing safe storage options for maintaining seed germinability, and for consumption and/or sale when food supplies are high, or when prices are low. Hermetic bags are economically feasible for use by subsistence farmers in Sub‐Saharan Africa for grain for household consumption and for carrying‐over seed for planting in the next season. Additional studies are needed to verify the mycotoxin contamination results and to determine if there are differences in functional food characteristics, e.g. flavor and cooking properties, that have not been as comprehensively studied. © 2023 The Authors.
