Training of trainer manual for production of Orange Fleshed Sweetpotato (OFSP): planting to harvesting
(IInternational Institute of Tropical Agriculture, 2023-07)Sweetpotato (Ipomoea batatas) originated in Central America or north-western South America from where it was introduced to Europe, Africa, Asia and North America in more recent times. Sweetpotato is now cultivated in nearly all parts of the tropics and sub-tropics as well as in the warmer parts of the temperate regions (CIP, 2019). This is because Sweetpotato is a dry-land crop, tolerant to a wide range of edaphic and climatic conditions. It is more tolerant of cold than other tropical root and ... -
Feminist research in agriculture: moving beyond gender-transformative approaches
(Springer, 2025)Feminist research approaches in agriculture are considerably underutilized. In this chapter, we suggest a few key reasons to help explain their lack of use in agriculture. We also provide background on what constitutes feminist research in agriculture through a review of the literature. Using a case study approach, we highlight the important and unique characteristics that define feminist research approaches in agriculture. The case studies provide examples of how researchers working in agriculture ... -
Etude de la possibilite de modelisation de la pate a pain a partir de la farine d'Ipomea batatas ou patate douce a chair blanche et a peau blanche
(l'Alliance Francaise d'Antsiranana, 2023-12-11)La farine de blé est la matière première la plus utilisée dans les différentes préparations des pâtes alimentaires en particulier, des pâtes à pains. Pourtant, son importation devient donc très onéreuse surtout pour les pays non producteurs. En conséquence, les coûts de production et le prix des produits de boulangerie sont devenus très chères. Or, Madagascar présente des ressources agricoles abondantes et variées qu’on peut transformer en farine y compris la patate douce (Ipomea batatas). Mais, ... -
The importance of the light spectrum in a high-throughput phenotyping lab concept: evaluating transpiration and biomass growth of different banana cultivars under different blue/red light ratios
(2020)The Bioversity International Musa Germplasm Transit Center holds the world's biggest collection of banana biodiversity (>1500 accessions). We aim to characterize this banana diversity for its suitability for specific agro-ecological conditions. To achieve this characterization, a lab-based model is needed to rapidly and objectively determine growth. Identifying a suitable light source that can help mimic relevant agro-ecological conditions is a challenge. LED lights are the most economical way to ... -

National food consumption and micronutrient survey 2021: final report
(Federal Government of Nigeria and International Institute of Tropical Agriculture, 2024-01)The last National Food Consumption and Micronutrient Survey (NFCMS) was undertaken about 20 years ago in 2001 (Maziya-Dixon, et al., 2004; Nigeria Food Consumption and Nutrition Survey 2001- 2003, IITA, https://hdl.handle.net/10568/100010). The findings of that study likely no longer represent the current micronutrient status or dietary consumption patterns of the Nigerian population. This lack of recent and reliable information presents several challenges, both in terms of reviewing ongoing ... -

Introduction: climate, cocoa and trees
(Springer, 2023-12-30)Climate change is predicted to significantly reduce areas suitable for the cultivation of cocoa, an important cash crop providing a livelihood to over six million smallholders in the humid tropics. Cocoa agroforestry shows potential to increase climate resilience while providing more stable incomes, enhancing biodiversity, supporting healthy ecosystems and reducing the pace at which farms expand into forested areas. Based on the multidisciplinary ‘Climate Smart Cocoa Systems for Ghana’ research ... -
Social challenges and opportunities in agroforestry: cocoa farmers’ perspectives
(Palmgrave Macmillan, 2024)Agroforestry practices in cocoa cultivation have historical roots going back to the Mayan sacred groves in Mesoamerica. Today, agroforestry cocoa, i.e., the integration of shade trees, plants and crops in cocoa systems, is promoted as a climate smart practice by public and private institutions. Shaded cocoa can sustain or even increase cocoa yields and the agroforestry systems may provide additional output for household consumption and sale as well as improve the microclimate and soil conditions ... -
Host plant resistance to insects in pulse crops
(Springer, 2024)Pulses are important sources of protein, dietary fiber, vitamins, and minerals for human nutrition and are widely cultivated in many countries around the world. Crops belonging to pulse include mainly chickpeas, mung bean, lentils, pigeon peas, and cowpeas. Pulse production and storage are negatively affected by a variety of biotic and abiotic factors, such as insect pests, diseases, parasites, low soil fertility, heat, and drought. Among these, insect pests have the most significant impact on ... -
Household economics of cocoa agroforestry: costs and benefits
(Palmgrave Macmillan, 2024)Current research suggests that cocoa agroforestry systems could offer stable yields, additional benefits and income from shade trees, despite potential added costs, such as from the purchase of insecticides. There is a paucity of profitability studies of different cocoa agroforestry systems. Only few of them go beyond a narrow focus on cocoa yields to model the entire agroforestry system and thus do not advance our understanding of the socio-economic value of other ecosystem goods. Based on survey ... -

Designing dioscorea genomes for improved nutritional and pharmaceutical properties
(Springer, 2023-12-15)Dioscorea species, commonly known as “Yams,” belong to family Dioscoreaceae consisting of about 600 species distributed from Africa, Asia, the Caribbean’s South America, and the South Pacific islands. The tuber of this genus is well known for their organoleptic properties, making them the most widely used food for carbohydrate, dietary supplements, and famine food. West Africa represents the region where yams are mostly consumed because of their underground and/or aerial tubers representing valuable ... -
Cocoa under heat and drought stress
(Springer, 2023)Cocoa (Theobroma cacao L.) is an important cash crop in many tropical countries, particularly in West Africa. Heat and drought are both known to affect the physiology of cocoa plants through reduced rates of photosynthesis and transpiration, as well as changed physiological processes such as the functions of photosystems, chlorophyll synthesis, stomatal conductance and expression of heat-shock proteins. This in turn leads to decreased yields and increased risks of mortality under severe heat and ... -

Agricultural transformation in maize producing areas of Africa
(IntechOpen, 2024-01)Maize is a critical staple cereal across Sub-Saharan Africa but attempts to improve its productivity in small-scale farming systems often prove disappointing. The 12 key technologies required to overcome poor yields are mostly known, but the manner that they are mobilized, packaged, and delivered requires re-evaluation. Combinations of better varieties and their necessary accompanying inputs must become more available and affordable for an African maize revolution to succeed, and land must be ... -
Nematode problems in tuber crops and their sustainable management
(Elsevier, 2023)In many subtropical and tropical countries, the most significant food commodities produced are those that are grown from tubers and roots (R&T). The R&T include yams (Dioscorea spp. L.), cassava (Manihot esculenta Crantz), and sweet potato (Ipomoea batatas (L.) Lam.) and edible aroids such as Taro (Colocasia esculenta Schott.) and Tannia (Xanthosoma sagittifolium Schott.). These crops represent the second-largest global source of carbohydrates, after cereals, in the tropical world, with a projected ... -
Improvement of nutraceutical traits of banana: new breeding techniques
(Springer, 2023-07-07)Banana (Musa spp.) is an herbaceous, everlasting green monocotyledonous plant belonging to the family Musaceae. It is a major staple crop after rice, maize, wheat, potato and cassava, and it has a high potential to contribute to food and nutrition security.
