They also used the opportunity to create more awareness about AYB\u2019s economic and nutritional benefits among farmers and other stakeholders.\n<div id=\"attachment_7884\" class=\"wp-caption aligncenter\">\n\n<a href=\"https:\/\/iita.org\/wp-content\/uploads\/2026\/06\/AfricaYam-bean1.jpg\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-7884\" src=\"https:\/\/iita.org\/wp-content\/uploads\/2026\/06\/AfricaYam-bean1.jpg\" alt=\"African Yam Bean (AYB): Rehabilitating a leguminous crop with many uses\" width=\"820\" height=\"411\" aria-describedby=\"caption-attachment-7884\" \/><\/a>\n<p id=\"caption-attachment-7884\" class=\"wp-caption-text\">African Yam Bean produces beans in pods above-ground and tubers beneath.<\/p>\n\n<\/div>\nIn the southwestern part of the country, particularly in Ekiti and Osun states, AYB attracts more patronage in terms of cultivation and consumption than other states in the region. The focus group discussion established that the cultivation of AYB in these states was still at the subsistence level with local processing for consumption. Ekiti farmers demonstrated this during the interview session through the displayed bean pods, shelled raw beans, and cooked AYB from their farms. The interview facilitator, Sarafat Tijani, acknowledged this, saying, \u201cEkiti growers are really into AYB cultivation and consumption.\u201d\n\nOn the knowledge of AYB cultivation and processing, most farmers stated that AYB is planted as a side crop or intercropped with other crops like yam and sorghum. As a vine crop, AYB shares staking with these crops or uses them (e.g., sorghum) as stakes.\n\nFarmers also shared their knowledge about planting AYB around April or latest May, but not delayed till June as this reduces yield obtainable from the crop. According to the farmers, AYB flowering stage starts in November; thus, a growing cycle from April to January yields a more remarkable harvest. The long growing cycle explains the reason for farmers\u2019 limited interest in AYB cultivation and its intercropping mode with other crops.\n<div id=\"attachment_7885\" class=\"wp-caption aligncenter\">\n\n<a href=\"https:\/\/iita.org\/wp-content\/uploads\/2026\/06\/AfricaYam-bean2.jpg\"><img decoding=\"async\" class=\"size-full wp-image-7885\" src=\"https:\/\/iita.org\/wp-content\/uploads\/2026\/06\/AfricaYam-bean2.jpg\" alt=\"African Yam Bean (AYB): Rehabilitating a leguminous crop with many uses\" width=\"820\" height=\"411\" aria-describedby=\"caption-attachment-7885\" \/><\/a>\n<p id=\"caption-attachment-7885\" class=\"wp-caption-text\">Bean-preneur team member and Tissue Culture Specialist Dr Morufat Balogun.<\/p>\n\n<\/div>\nBesides the long growing process, cooking AYB for consumption was also reported to take so long that it has to be cooked over the night to soften. Farmers identified other uses to which AYB can be put, such as processing and grinding into a paste with pepper and onion to make bean cake and\u00a0<em>moin-moin<\/em>\u00a0and other food delicacies made from other beans.\n\nThe challenges notwithstanding, farmers agreed that the crop\u2019s economic and nutritional benefits could not be over-emphasized. Its cultivation enhances soil fertility through nodulation as a leguminous crop, and it increases the yield of other crops. However, the Project Supervisor Ademola Aina\u2019s observation on the simultaneous production of tubers in underground and bean seeds in pods by some AYB crop varieties is yet to be confirmed by some farmers\u2019 representatives, particularly from Oyo State.\n\nMore awareness on AYB will encourage growers to explore additional income from AYB (tuber production). Furthermore, the respondents unanimously agreed that AYB could be regarded as a promising food crop in combating protein-energy malnutrition due to its high nutritional profile (protein from the beans and carbohydrates from its tuber). It is also a food crop with the potential to improve food security significantly.\n\nBased on farmers\u2019 recommendation to develop improved varieties that are early maturing and with a shortened bean-cooking time, and consequent assurance of availability of this request, the Bean-preneur team recommends more sensitization among farmers within their groups in the selected states. Farmers\u2019 representatives in the less AYB informed Oyo State expressed their motivation and willingness to go into the production of AYB based on the ideas shared during the interview.\n\nTissue Culture Specialist\u00a0<a href=\"https:\/\/iita.org\/fr\/iita-staff\/balogun-morufat\/\">Morufat Balogun<\/a>\u00a0stated that, after identifying challenges with AYB cultivation, the project team at\u00a0<a href=\"https:\/\/iita.org\/fr\/\">IITA<\/a>, with collaborating partners and other interested scientists, will target breeding programs for AYB improvement. They will also establish a commercial value chain that is all-inclusive for efficient consumer satisfaction.","protected":false},"excerpt":{"rendered":"<p>To revitalize underutilized crops in Africa, the \u201cBean-preneur\u201d team organized exploratory interviews with African Yam Bean (AYB) growers and non-AYB growers in Nigeria to identify its cultivation and utilization challenges<\/p>","protected":false},"featured_media":15088,"template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"tags":[],"science-area":[],"program":[],"location":[32],"news-type":[],"hub":[61],"crop":[],"impact-areas":[],"item-year":[199],"class_list":["post-15087","news-item","type-news-item","status-publish","has-post-thumbnail","hentry","location-nigeria","hub-western-africa","item-year-199"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.2 -
