Slow but sure: the potential of slow-release nitrogen fertilizers to increase crop productivity and farm profit in Nepal
(2022-04-27)Reduction of nitrogen (N) input in cropping systems is critical to reduce environmental pollution and achieve sustainable development goals. Multi-location field trials for maize (n = 120) and rice (n = 84) were conducted across nine districts in Nepal during 2018 and 2019 to assess the potential of polymer coated urea (PCU) and urea briquette (UB) to increase agronomic N use efficiency (AEN), crop productivity and farm profits over conventional urea (CU). Nitrogen rates applied in PCU and UB ... -
Evaluation of starches digestibility and glycemic index of commonly consumed sstaple foods from selected varieties of cassava (Manihot sp.) and yam (Dioscorea sp.)
(University of Ibadan, 2019-08)Consumption of high Glycemic Index (GI) foods is a risk factor for increasing prevalence of metabolic related non-communicable diseases. Cassava and yam are among common staples known to have high GI and are usually avoided by diabetics because they can rapidly raise blood glucose. Currently, it is still unclear if common varieties (and their corresponding products) have different starch digestibility and GI. This study was therefore designed to evaluate starch digestibility and GI of common foods ... -
Unravelling the diversity and distribution of the soybean rust fungus Phakopsora pachyrhizi in east Africa
(Wageningen University and Research, 2019-02)Soybean is an important legume crop that is cultivated worldwide on more than 120 million hectares, producing more than 330 million tonnes of soybeans annually. Soybeans contain 40% of protein and 20% of oil and the crop is therefore used both for human and livestock consumption. Generally, soybean has the potential to significantly improve the nutrition of the inhabitants of sub-Saharan Africa. Soybean production has intensified in Africa over the past 15 years, owing to the raising demand driven ... -

Food sovereignty in sub-Saharan Africa: reality, relevance, and practicality
(2022-10-07)The recent discourse on food sovereignty places much emphasis on democracy in determining localized food systems, and whether the food is culturally appropriate while leaning heavily on sustainable agricultural practices such as organic agriculture, ecological intensification, agroecology, naturebased solutions, and regenerative agriculture. Sustainable agricultural practices are intended to ensure that the land is managed without the use of synthetic fertilizers and pesticides, while going further ... -
National food consumption and micronutrient survey 2021: preliminary report
(IInternational Institute of Tropical Agriculture, 2022-09)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 ... -

Residues from black soldier fly (Hermetia illucens) larvae rearing influence the plant-associated soil microbiome in the short term
(2022-09-26)The larvae of the black soldier fly (BSFL, Hermetia illucens) efficiently close resource cycles. Next to the nutrient-rich insect biomass used as animal feed, the residues from the process are promising plant fertilizers. Besides a high nutrient content, the residues contain a diverse microbial community and application to soil can potentially promote soil fertility and agricultural production through the introduction of beneficial microbes. This research assessed the application of the residues ... -
Re-assessing the pest status of Tetranychus evansi (Acari: Tetranychidae) on solanaceous crops and farmers control practices in Benin
(2022-12)This study was carried out 7 years after a first one conducted in 2013 as part of the policy of the Benin government to promote the vegetable production sector. Data collection was mostly based on a countrywide survey conducted in 25 municipalities throughout Benin, from August to December 2020. Farmers were selected based on their experience in cultivating solanaceous crops, and were interviewed to assess their perception about the severity of the spider mite Tetranychus evansi, the control method ... -
Biomass production and nutrient use efficiency in white Guinea yam (Dioscorea rotundata Poir.) genotypes grown under contrasting soil mineral nutrient availability
(2022)Yam (Dioscorea spp.) is of great importance to food security, especially in West Africa. However, the loss of soil fertility due to dwindling fallow lands with indigenous nutrient supply poses a challenge for yam cultivation. This study aimed to determine shoot and tuber biomass and nutrient use efficiency of white Guinea yam (Dioscorea rotundata) grown under low- and high-NPK conditions. Six white Guinea yam genotypes were used in field experiments conducted at Ibadan, Nigeria. Experiments were ... -
Genetic diversity and inter-trait relationships among maize inbreds containing genes from Zea diploperennis and hybrid performance under contrasting environments
(2020)Accurate estimation of genetic variability present in tropical maize inbreds with varying reactions to Strigahermonthica infestation is essential for efficient and sustainable utilization to ensure increased genetic gain in a breeding program. Thirty-six early maturing maize inbred lines and 156 single cross hybrids were evaluated under Striga-infested and non-infested conditions in Nigeria during the 2014 and 2015 cropping seasons. Under Striga infestation, grain yield ranged from 1134 kg ha−1 ... -
The potential of conservation agriculture to improve nitrogen fixation in cowpea under the semi-arid conditions of Kenya
(2022-10-07)Low-cost but productive crop intensification options are needed to assist smallholder farmers in the tropics to move away from poverty. This study assessed the capacity of cowpea (Vigna unguiculata (L.) Walp.) to perform biological N fixation (BNF) under no-tillage practices, crop residue cover and intercropping with maize (Zea mays L.). The study was performed during the long rains of 2017 at Kiboko experimental station, located in semi-arid eastern Kenya. The research field trials had been running ... -
Cómo abordar la temática de género en el manejo de plagas y enfermedades: Preguntas y respuestas frecuentes sobre la recolección de datos y trabajos de extensión con enfoque de género
(International Potato Center, 2020-08)Este resumen explora el potencial y los beneficios que se pueden obtener al aplicar la perspectiva de género en la investigación y extensión agrícola.
