    • Prospects and potential of bradyrhizobium diazoefficiens based bio-inoculants on soybean production in different agro-ecologies of Mozambique 

      Engoke, C.; Wiredu, A.N.; Chikoye, D.; Boahen, S. (2022-07)
      Soybean production in sub-Saharan Africa is increasing as farmers open more land areas for cultivation and replace other crops, such as tobacco, in favor of this legume crop. Despite the production is increased in Mozambique, demand for animal feed and oil is not satisfied. As such, farmers explore ways to improve yield per unit area of soybean by using bio-inoculants from various sources and agroecological adaptability. These bio-inoculants are seldom available during planting time, and retail ...

    • Turning waste to wealth: harnessing the potential of cassava peels for nutritious animal feed 

      Okike, I.; Wigboldus, S.; Samireddypalle, A.; Naziri, D.; Adesehinwa, A.O.K.; Adejoh, V.A.; Amole, T.; Bordoloi, S.; Kulakow, P. (Springer, 2022)
      In Nigeria, processing cassava for food and industry yields around 15 million tons of wet peels annually. These peels are usually dumped near processing centres to rot or dry enough to be burned. Rotting heaps release methane into the air and a stinking effluent that pollutes nearby streams and underground water, while burning produces clouds of acrid smoke. However, when properly dried, peels can be an ingredient in animal feed. Previous attempts over two decades to use peels in animal feed ...

    • Building demand-led and gender-responsive breeding programs 

      Polar, V.; Teeken, B.; Mwende, J.; Marimo, P.; Tufan, H.A.; Ashby, J.A.; Cole, S.M.; Mayanja, S.; Okello, J.J.; Kulakow, P.; Thiele, G. (Springer, 2022)
      Gender-responsive breeding is a new approach to making sure modern breeding takes advantage of opportunities to improve gender equality in agriculture. Conventional research on the acceptability of modern varieties has scarcely addressed gender differences during adoption studies. Gender-responsive breeding starts from a different premise that adoption and social impact will be enhanced if gender is addressed at early stages of variety design and priority setting in breeding. However, until recently, ...

    • Estimate App for yam anthracnose disease phenotyping: user guide 

      Kolade, O.; Kumar, P.L. (IInternational Institute of Tropical Agriculture, 2021)

    • Towards spatially continuous mapping of soil organic carbon in croplands using multitemporal Sentinel-2 remote sensing 

      Shi, P.; Six, J.; Sila, A.; Vanlauwe, B.; Van Oost, K. (2022-11)
      Intensified human activities can augment soil organic carbon (SOC) losses from the world’s croplands, making SOC a highly dynamic parameter both in space and time. Sentinel-2 spectral imagery is well placed to capture the spatiotemporal variability of SOC, but its capability has only been demonstrated for agricultural regions mostly located in Europe. Furthermore, most studies so far only used single-date images that resulted in spatially non-continuous SOC maps, hampering their ability to aid ...

    • Suitability of testers to characterize provitamin a content and agronomic performance of tropical maize inbred lines 

      Sayadi Maazou, A. R.; Adetimirin, V.; Gedil, M.; Meseka, S.K.; Mengesha Abera, W.; Menkir, A. (2022)
      Vitamin A deficiency poses health risks for children, pregnant women, and nursing mothers in sub-Saharan Africa (SSA) and Southeast Asia. Provitamin A–biofortified maize varieties can contribute to minimizing the adverse effects of vitamin A deficiency in areas where maize is a staple food crop. Identifying suitable testers is important to breed provitamin A–biofortified hybrid maize. This study was therefore conducted to 1) assess the suitability of maize inbred lines with contrasting levels of ...

    • Household livelihood diversification in rural Africa 

      Musumba, M.; Palm, C.A.; Komarek, A.M.; Mutuo, P.; Kaya, B. (2022-03)
      Diversification is a common livelihood strategy for rural households in developing countries, with diversification being either a choice or necessity depending on individual household contexts. Using two waves of data (from 2009 and 2011) for 1773 households from eight countries in sub-Saharan Africa, we examined livelihood diversification and its drivers. We examined livelihood diversification by considering household involvement in three livelihood activities: crop, livestock, and non-farm. ...

    • Genotype by environment interaction and grain yield stability of drought tolerant cowpea landraces in Ethiopia 

      Mekonnen, T.W.; Mekbib, F.; Amsalu, B.; Gedil, M.; Labuschagne, M. (2022)
      Cowpea is one of the most important indigenous food and forage legumes in Africa. It serves as a primary source of protein for poor farmers in drought-prone areas of Ethiopia. The crop is used as a source of food, and insurance crop during the dry season. Cowpea is adaptable to a wide range of climatic conditions. Despite this, the yield of the crop is generally low due to lack of stable and drought-tolerant varieties. In this study, 25 cowpea genotypes were evaluated in five environments using a ...

    • Understanding gendered trait preferences: implications for client-responsive breeding programs 

      McDougall, C.; Kariuki, J.; Lenjiso, B.M.; Marimo, P.; Mehar, M.; Murphy, S.; Teeken, B.; Akeste, M.J.; Benzie, J.; Galie, A.; Kulakow, P.; Mekkawy, W.; Nkengla-Asi, L.; Ojango, J.M.K.; Tumuhimbise, R.; Uwimana, B.; Orr, A. (2022)
      Client-responsiveness is a foundation for effectiveness of public sector breeding programs in agriculture, aquaculture and livestock. However, there remains a considerable lack of clarity about what this means, specifically in terms of how programs can be gender-responsive. This study contributes to addressing that need. It does so through sharing higher-level insights emerging from the combined experiences of eight gendered trait preference cases from across nine countries in Asia and Africa. The ...

    • Long-term evidence for ecological intensification as a pathway to sustainable agriculture 

      MacLaren, C.; Mead, A.; van Balen, D.; Claessens, L.; Etana, A.; de Haan, J.; Haagsma, W.; Jack, O.; Keller, T.; Labuschagne, J.; Myrbeck, A.; Necpalova, M.; Nziguheba, G.; Six, J.; Strauss, J.; Swanepoel, P.A.; Thierfelder, C.; Topp, C.; Tshuma, F.; Verstegen, H.; Walker, R.; Watson, C.; Wesselink, M.; Storkey, J. (2022-09)
      Ecological intensification (EI) could help return agriculture into a ‘safe operating space’ for humanity. Using a novel application of meta-analysis to data from 30 long-term experiments from Europe and Africa (comprising 25,565 yield records), we investigated how field-scale EI practices interact with each other, and with N fertilizer and tillage, in their effects on long-term crop yields. Here we confirmed that EI practices (specifically, increasing crop diversity and adding fertility crops and ...

    • Cassava farmers' insights and seed dealers enterprises in Nigeria 

      Balogun, D.O. (University of Ibadan, 2019)
      Seed enterprise is an initiative and risk set up in the production of cassava stems from existing local seed varieties or improved seed varieties for economically sustainable profit. Although, most cassava seeds produced are through informal seed system among smallholder farmers but there is need for replacement strategy for cassava seeds mostly planted over years. Based on this, there is need for intense exploration in the linkage between cassava seed management and diffusion scheme among rural ...

    • Genetic diversity and nitrogen fixation in underutilized tropical legumes 

      Adegboyega, T.T. (North-West University, 2019-07)
      Legumes in some cases are underutilized and form only a relatively small proportion of human diets. In general they fix atmospheric nitrogen which may provide an economic advantage for smallholder farmers. By appropriate utilization of legumes, food security and soil fertility can be significantly achieved. During the 2016/2017 and 2017/2018 cropping seasons at the International Institute of Tropical Agriculture (IITA) Ibadan, Nigeria, field and laboratory experiments were conducted to determine ...

    • Reduction of tomato losses through implementation of simple postharvest techniques using rosemary (Rosmarinus officinalis) essential oil in Bushi, Democratic Republic of the Congo 

      Sibomana, I.C. (University of Yaounde, 2020)
      Tomato is perishable and its high moisture content makes it susceptible for various postharvest losses. Tomato quality changes continuously after harvesting when fruits start losing quality because of environmental stress and pathogen infection. Thus, the objective of this research was to propose simple postharvest technology using rosemary essential oil (REO) to reduce postharvest decay. This was done by conducting a field survey in order to determine agricultural potential of soil and environmental ...

    • The role of knowledge in the acceptance of organic and human waste recycling: the case of Rwanda's food system 

      Vogel, S. (Swiss Federal Institute of Technology, 2020-05-15)
      By 2050, the world’s population is expected to increase to 9 billion people. The growing population intensifies urbanization, which puts pressure on the current challenges of food insecurity and environmental pollution. In Rwanda, rural migration and the lack of financial capital to apply sufficient fertilizer result in nutrient-deficient agricultural soils which lead to a decrease in food production. Moreover, the rapid urban expansion leads to environmental pollution and human health risks from ...

      Oladimeji, T.E. (Ahmadu Bello University, 2019-09)
      The adoption of soil conservation practices is important for sustaining Nigerian agriculture where smallholder maize farmers face constraints such as low soil fertility that lead to low productivity and food insecurity. This study aims to analyze the effect of soil conservation on productivity and food security of maize farmers in Northwest Nigeria. The study used a two year panel data of 792 maize farmers for 2016 and 2017 cropping seasons, collected by IITA under “Taking Maize Agronomy to Scale ...

    • Optimising locally available resources for nutrient management to improve banana productivity in the farming systems in Rombo District, Kilimanjaro region 

      Rutazaha, J.E. (Sokoine University of Agriculture, 2019)
      Banana is an important staple food in East Africa and an essential cash crop in the national and local economies. In Kagera and Kilimanjaro regions of Tanzania, banana is cultivated by more than 70% of smallholder farmers as a staple food in home gardens ranging from 0.5 to 2 hectares. Decline in banana yield has been reported in banana farming systems as a result of abiotic constraints (nutrient deficiencies and drought stress) and biotic constraints (pests and diseases). Decline in soil fertility ...

    • Effect of organic amendment on soil carbon dynamics in agricultural ecosystems 

      Hamamoto, T. (Hokkaido University, 2020-03-25)
      Soil carbon (C) contents and dynamics are important in the maintenance of health soils. Organic amendments (e.g. crop residue and organic manure) are known as materials to increase soil C. The degradation of organic amendments and physical disturbance of soils, performed by the fauna, can alter soil microbial community, and thus influence rates of the C cycles. However, little is known about the interaction between different soil biological communities (i.e. soil fauna and microbes) regarding soil ...
