      Mossie, T.; Biratu, K.; Yifred, H.; Silesh, Y.; Abebe, A.T. (2024-04-15)
      Soybean is a leguminous crop known for its multiple utilizations both as food and feed for humans and livestock. The objectives of the study were to identify high dry matter yielder and stable genotypes across environments in southwestern Ethiopia. The effect of genotype environment (G x E) interaction on dry matter yield of soybean genotypes were evaluated in two cropping seasons (2019–2020) under rain fed condition. Eight pre tested soybean genotypes with two checks were used as treatment in a ...

    • Variation among cassava (Manihot esculenta Crantz) genotypes for storage root yield, yield components and response to cassava mosaic disease at the advanced breeding stage 

      Mahamane, A.O.; Olasanmi, B.; Udemba, I.O.; Mbanjo, E.G.N. (2024-06-19)
      Cassava is a crucial starchy root crop cultivated worldwide in tropical and subtropical areas. Efforts have been made to improve its desirable characteristics to increase food and nutritional quality. However, the adoption of new cassava varieties can be influenced by their yield performance, which can be affected by cassava mosaic disease (CMD). The present study evaluated selected cassava genotypes' performance across two years at the advanced breeding stage. Using a randomized complete block ...

    • Variations in micronutrient concentrations and retentions in fufu made from yellow-fleshed cassava as a function of genotype and processing methods 

      Williams-Ngegba, M.S.E.; Onabanjo, O.O.; Anthony, N.M.; Alamu, E.O.; Maziya-Dixon, B.; Oguntona, E.B. (2024-05-22)
      Introduction The biofortification of staple foods such as cassava is one of the technological breakthroughs in the nutritional improvement of foods. Fufu is one of the fermented cassava products produced and consumed in major West African countries, including Sierra Leone, and the majority of the processes involved in its production have direct and indirect effects on its properties. This study looked at how the concentration and retention of micronutrients in yellow-fleshed cassava fufu varied ...

      Gbegbelegbe, S.; Chikoye, D.; Alene, A.; Kyei-Boahen, S.; Chigeza, G. (2024-02-14)
      Southern Africa has been experiencing long-term changes in its climate and future projections imply that droughts should last longer and become more intense in southern Africa. Already, the region has been experiencing an increase in consecutive drought years. This study contributes to the literature by using bio-economic modeling to simulate the impact of future droughts on food security in southern Africa and identify plausible pathways for enhancing regional food security under drought. Food ...

    • Training of trainer manual for production of Orange Fleshed Sweetpotato (OFSP): planting to harvesting 

      Olasanmi, B.; Abioye, O.; Olorode, B.; Peters, G.; Udemba, I.O.; Adiga, S.; Banwo, O.; Akande, A. (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 ...

    • Econometric analysis of disseminating sustainable intensification practices: evidence from Ghana 

      Bedi, S.M. (Rheinischen Friedrich-Wilhelms-Universitat, 2021)
      Adoption of sustainable intensification (SI) of agricultural practices is essential for increasing food production in more sustainable way. Dis-adoption of agricultural technologies is pervasive among smallholder farmers in sub-Saharan Africa after withdrawal of most programme interventions. Based on data collected from 700 farm households of an agricultural research for development programme in northern Ghana. This study i) examines alternative ways of inducing farmers into adopting new agricultural ...

      Sansa, O.; Abberton, M.T.; Ariyo, J.; Paliwal, R.; Ige, A.; Dieng, I.; Ayo-Vaughan, M.; Olowe, V.I.; Oyatomi, O. (2024-10-04)
      Exploring genomic regions linked with drought tolerance and photosynthesis in cowpea could accelerate breeding of climate-resilient cowpea varieties. A genome-wide association study (GWAS) was conducted to identify marker–trait associations for agronomic and photosynthetic traits measured under well-watered and water-stressed conditions. One hundred and twelve cowpea accessions from IITA were phenotyped for agronomic and photosynthetic traits across 3 locations in 2 years: Ibadan, Ikenne (2020 and ...

      Aghogho, C.I.; Kayondo, S.I.; Eleblu, S.J.Y.; Ige, A.; Asante, I.; Offei, S.K.; Parkes, E.; Egesi, C.; Mabanjo, E.G.N.; Shah, T.; Kulakow, P.; Rabbi, I.Y. (2024-06-16)
      The starchy storage roots of cassava are commonly processed into a variety of products, including cassava granulated processed products (gari). The commercial value of cassava roots depends on the yield and quality of processed products, directly influencing the acceptance of new varieties by farmers, processors, and consumers. This study aims to estimate genetic advance through phenotypic selection and identify genomic regions associated and candidate genes linked with gari yield and quality. ...

    • Genetic analysis and drought stress assessment of marker-based improved provitamin-A maize synthetics 

      Iseghohi, O.I. (University of Ibadan, 2023-07)
      Maize is an important staple in Sub-Saharan Africa (SSA) but most varieties are low in Provitamin-A (PVA) carotenoids, and the performance adversely affected by drought stress. Development and adoption of PVA carotenoids-enriched drought-tolerant Maize Synthetics (MS) could help improve maize yields and reduce vitamin A deficiency in SSA. Marker Assisted Recurrent Selection (MARS) could be used to improve the nutritional quality and resilience of maize. However, the effects of MARS on carotenoid ...

    • Assessment of climate change impact and adaptation strategy for millet in the Sudano‑Sahelian region of Niger 

      Tofa, A.I.; Kamara, A.Y.; Mohamed, A.M.L.; Garba, M.; Souley, A.M.; Salissou, H.; Kapran, B.I.; Abdoulaye, T. (2024-10-03)
      Pearl millet is an important food and fodder crop in West African semi-arid regions. Climate change is projected to have a significant impact on the productivity of the crops in these regions. Adaptation strategies to sustain agricultural production are therefore urgently required to sustain millet productivity. The Decision Support System for Agrotechnology Transfer (DSSAT) CERES-Millet model was used to assess the impact of climate change and adaptation strategies on millet in Niger. Three millet ...

    • Adoption of agronomic practices and their impact on crop yield and income: an analysis for black gram and green gram in India 

      Varma, P.; Manda, J. (2024)
      Black gram and green gram are important pulse crops in India, but their production has faced fluctuations and stagnancy in yields over the last few decades. The Government of India has implemented several measures to enhance crop yield, including recommending and promoting the adoption of crop-specific agronomic practices. However, there is limited empirical evidence on the determinants of the adoption of these practices and their impact on yield and income. In this context, this study analyses ...
