“…Starting in 2004, Burkina Faso developed a rural development strategy that took into account crop diversification, including cowpea [29]. This study showed that crop diversification has an additive effect with WCM as a resilience strategy for nutritional food security and income security and is consistent with others [30]. In both cowpea production years and sorghum following cowpea years, grain and stover revenue was significantly higher in the crop rotation system (Figures 8 and 9).…”

Resilience of smallholder farmers in their ability to bounce-back and overcome shocks, such as drought, is critical to ensure a pathway out of hunger and poverty. Efficient water conservation methods that increase rainwater capture and reduce soil erosion such as stone lines and grass bands are two technologies that have been proposed to increase the resilience in Sudano–Sahelian farming systems. In Burkina Faso, we show that stone lines, grass bands, and crop rotation are effective resilience strategies individually and in combination. During years when rainfall is well-distributed over time, differences are minimal between fields with water conservation methods and fields without. However, when there are periods of prolonged drought, water conservation methods are effective for increasing soil water, yield, revenue, and resilience. During drought conditions, sorghum (Sorghum bicolor (L.) Moench) grain yield and revenue with stone lines and grass bands were over 50% greater than that of the control, by an average of 450 kg ha−1, which amounted to an increase of 58,500 West African CFA franc (CFA) ha−1 (i.e., 98 USD ha−1). The results also suggest that the combination of water conservation method and crop rotation additionally improves cropping system productivity and revenue. Growing cowpea (Vigna unguiculata (L.) Walp.) in rotation with sorghum production provided more options for farmers to increase their income and access to nutrition. This study also sheds light on the limited productivity gains due to improved crop varieties. The local sorghum landrace, Nongomsoba, and the local cowpea variety in rotation resulted in the highest yields as compared to the improved varieties of Sariaso 14 sorghum and KVX 396-4-4 cowpea. Under similar low input/degraded conditions, improved crop varieties likely are not a suitable resilience strategy alone. We conclude that during erratic rainy seasons with frequent periods of drought (i.e., water stress) in rain-fed conditions in Burkina Faso, stone lines or grass bands in combination with sorghum and cowpea rotation are effective practices for increasing resilience of smallholder farmers to maintain crop productivity and revenue. With future and present increases in climate variability due to climate change, stone lines, grass bands, and crop rotation will have growing importance as resilience strategies to buffer crop productivity and revenue during periods of drought.

“…C'est pourquoi sur le périmètre de Djirataoua et le long de la vallée du Goulbi N'Maradi, les producteurs s'adonnent à la pratique de ces cultures. Dabat et al (2012) ont rapporté pour une densité de 5000 pieds/ha (densité en milieu paysan), la valeur de fanes est estimée à 125 000 FCFA, alors que les 300 kg de grains produits, ne valent que 75 000 FCFA. Les prix des fourrages varient selon les lieux et les périodes (Mahamadou, 2004 ;Manzo, 2009 ;Maman, 2014 …”

11643Estimated yields and economic profitability for the production of three crops : sorghum, cowpea and dolic to Djirataoua (Maradi, Niger Republic)ABSTRACT Objectives : Production test on sorghum, cowpeas and dolic peas was conducted in 2014 on an irrigated perimeter of Djirataoua. It aimed to estimate forage and grain yields, chemical analysis of forage and evaluate the economic profitability of the three crops.Methodology and results : The test was set in a randomized complete block design with three plots in four replicates. The basic plot had a size of 5m x 100m. The agronomic data was collected on the growth cycle of crops, while economic data covered the cost of inputs, labor costs for the work and prices of various products and by-products obtained at harvest. Fodder and grain yields were evaluated. For fodder, the results obtained were 8.6 ± 0.7 tons ha-1 DM, 5.6 ± 0.74 tons ha-1 DM and 4 ± 0.74 tons ha-1 DM respectively for Sorghum, cowpea and dolic peas. Grain yields were 3.4 ± 0.65 tons ha-1 for sorghum, 1.2 ± 0.65 tons ha-1 for cowpea, and dolic peas yield is zero because it is a photosensitive plant. Chemical analysis of the biomass showed that the three crops had a comparable DM content, whereas cowpeas and dolic peas were richer in total nitrogenous matter (TNM) than sorghum. The content of TNM is 8% for sorghum; it is double in cowpea and triple in dolic peas. Conclusion and applications of results:This study shows that the dual-purpose crops, sorghum and cowpea provide an important forage yield meaning a high density and good soil fertility and good crop maintenance. This can be a cure for the chronic fodder deficit in Niger and will increase livestock productivity and farmers' income.

“…All parts of cowpea are used as food: (a) the leaves, green peas, green pods, and dry grain are consumed as different dishes; (b) its parts supply vitamins and minerals, especially micronutrients; and (c) the grain is especially rich in the amino acids lysine and tryptophan (AATF 2012). Cowpea is harvested during the dry season, when wet season crops are scarce, helping to mitigate hunger and scarcity (Dabat, Lahmar, and Guissou 2012;Ugbe et al 2016).…”
