Fertilizer Microdosing and ?Warrantage? or Inventory Credit System to Improve Food Security and Farmers? Income in West Africa
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
The fertilizer microdosing technology deals with the application of small quantities of fertilizers in the planting hole, thereby increasing fertilizer use efficiency and yields while minimizing input costs. In drought years, microdosing also performs well, because larger root systems are more efficient at finding water, and…

Molecular profiling of an interspecific rice population derived from a cross between WAB 56-104 (Oryza sativa) and CG 14 (Oryza glaberrima)
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
NERICA rices are interspecific inbred progeny derived from crosses between Oryza sativa × O. glaberrima. In this study, we evaluated 70 BC2 interspecific lines, developed by crossing a tropical japonica variety (WAB 56-104) as the recurrent parent to an O. glaberrima variety (CG 14) as the donor parent, followed…

Energy-Dispersive X-ray Fluorescence Spectrometry for Cost-Effective and Rapid Screening of Pearl Millet Germplasm and Breeding Lines for Grain Iron and Zinc Density
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
Comparison of energy-dispersive X-ray fluorescence (XRF) and inductivelycoupled plasma-optical emission spectroscopy (ICP) for iron (Fe) and zinc(Zn) densities in pearl millet grain samples from 11 trials showed significantdifferences between these two methods for both micronutrients. XRF…

Economic trade-offs of biomass use in crop-livestock systems: Exploring more sustainable options in semi-arid Zimbabwe
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
In complex mixed crop-livestock systems with limited resources and biomass scarcity, crop residues play an important but increasingly contested role. This paper focuses on farming systems in the semi-arid areas of Zimbabwe, where biomass production is limited and farmers integrate crop and livestock activities. Conservation…

Climate, soil and land-use based land suitability evaluation for oil palm production in Ghana
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
In the past decade, oil palm (Elaeis guineensis Jacq.) has become the world?s most important oil crop. The large demand for palm oil has resulted in a rapid expansion of oil palm cultivation across the globe. Because of the dwindling availability of land in Southeast Asia, most expansion of the industry is expected in Central and South America and sub-Saharan…

Legume genetic resources: management, diversity assessment, and utilization in crop improvement
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
Grain legumes contribute significantly to total world food production. Legumes are the primary source of dietary proteins in many developing countries, where protein hunger and malnutrition are widespread. Grain legumes germplasm constitute ~15% of the 7.4 M accessions preserved globally. Nearly, 78% of the CGIAR?s, 0.217 M accessions, have been…

Pushing the envelope? Maize production intensification and the role of cattle manure in recovery of degraded soils in smallholder farming areas of Zimbabwe
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
Soil fertility decline is a major constraint to crop productivity on smallholder farms in Africa. The objective of this study was to evaluate the long-term (up to nine years) impacts of nutrient management strategies and their local feasibility on crop productivity, soil fertility status and…

Creating long-term weather data from thin air for crop simulation modeling
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
Simulating crop yield and yield variability requires long-term, high-quality daily weather data, includingsolar radiation, maximum (Tmax) and minimum temperature (Tmin), and precipitation. In many regions,however, daily weather data of sufficient quality and duration are not available. To overcome this limitation,we evaluated a new method to create long-term weather series…

Adapting to a new urbanizing environment: gendered strategies of Hanoi’s street food vendors
International Potato Center (CIP)
https://hdl.handle.net/10568/89931
Abstract
Drawing upon examples of street vendors in Hanoi, this study explores gendered strategies to adapt to rapid urbanization, and how street vendors’ responses, in turn, shape the current informal food systems. The findings show that Hanoi’s informal food system is organized based on social, as well as economic, interactions and therefore the system’…

Climate-Smart Agricultural Value Chains: Risks and Perspectives
World Agroforestry Centre (ICRAF)
Abstract
Extreme weather is causing significant problems for smallholder farmers and others who depend on agricultural value chains in developing countries. Although value-chain analysis can help untangle the complex relationships within agricultural systems, it often has failed to take into account the effects of climate change. Climate-change assessments, meanwhile, often focus on the production node while neglecting other components…

Prioritizing climate-smart livestock technologies in rural Tanzania: A minimum data approach
World Agroforestry Centre (ICRAF)
Abstract
Crop-livestock production systems play an important role in the livelihoods of many rural communities in sub-Saharan Africa (SSA) but are vulnerable to the adverse impacts of climate change. Understanding which farming options will give the highest return on investment in light of climate change is critical information for decision-making. While there is continued investment in testing adaptation…

Mapping Soil Properties of Africa at 250 m Resolution: Random Forests Significantly Improve Current Predictions
World Agroforestry Centre (ICRAF)
Abstract
80% of arable land in Africa has low soil fertility and suffers from physical soil problems. Additionally, significant amounts of nutrients are lost every year due to unsustainable soil management practices. This is partially the result of insufficient use of soil management knowledge. To help bridge the soil information gap in Africa, the Africa Soil Information Service (AfSIS)…

Marker-free PLRV resistant potato mediated by Cre-loxP excision and RNAi
International Potato Center (CIP)
https://hdl.handle.net/10568/76626
Abstract
An inverted repeat construct corresponding to a segment of the potato leaf roll virus coat protein gene was created under control of a constitutive promoter and transferred into a transformation vector with a heat inducible Cre-loxP system to excise the nptII antibiotic resistance marker gene. Fifty-eight transgenic events were evaluated for resistance to PLRV by…
