Cowpea grains constitute a nutritious food to humans, while resource-poor farmers use its fodder and shell in fattening livestock during the dry season in Niger. Owing to the high price of these commodities, especially in the hot, dry season, the development and adoption of dual-purpose varieties adapted that period may significantly lower the cost of cowpea products to farmers. To that end, 12 cowpea genotypes were evaluated for high grain and forage yield at three INRAN research stations during the hot, dry season of 2021. The data collected were analyzed with R software and the results revealed significant differences among genotypes for grain and fodder yields. IN17_142 and IN15_62 turned out to be the best performing cultivars with 1198.3 kg/ha and 1187.5 kg/ha as mean grain yield and 3790.0 kg/ha and 3542.0 kg/ha in terms of mean fodder yield. However, above 2 and 6 tons mean grain and fodder yields per hectare were recorded by each of these two genotypes at Maradi. High positive relationships were detected between grain and fodder yields, as a result, the winning lines are the same for the two traits. Dual-purpose varieties suited for cowpea production in the hot dry season of Niger are detected in this work and its adoption by farmers may help boost the production.
豇豆籽粒是人类的营养食品，而资源匮乏的农民在尼日尔的旱季用其饲料和豆荚来育肥牲畜。由于这些商品价格高昂，尤其是在炎热干燥的季节，培育和推广适应该时期的两用品种可能会显著降低农民的豇豆产品成本。为此，在2021年炎热干燥的季节，在三个国家农业研究与创新研究所（INRAN）的研究站对12个豇豆基因型进行了高籽粒产量和饲草产量评估。收集的数据用R软件进行分析，结果显示不同基因型在籽粒产量和饲料产量上存在显著差异。IN17_142和IN15_62是表现最佳的品种，平均籽粒产量分别为1198.3公斤/公顷和1187.5公斤/公顷，平均饲料产量分别为3790.0公斤/公顷和3542.0公斤/公顷。然而，在马拉迪，这两个基因型的每公顷平均籽粒产量和饲料产量均超过2吨和6吨。籽粒产量和饲料产量之间检测到高度正相关，因此，这两个性状的优胜品系相同。本研究发现了适合尼日尔炎热干燥季节豇豆生产的两用品种，农民采用这些品种可能有助于提高产量。
