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. Si bien muchas personas reconocerían fácilmente la importancia del género en cualquier tipo de investigación agrícola, los métodos y las técnicas para la aplicación de esta perspectiva no son siempre tan obvios ni fáciles de llevar a la práctica. A continuación presentamos una guía útil de preguntas y respuestas preparadas por el equipo interdisciplinario ... -

Considering gender in pest and disease management: FAQs for gender-responsive data collection and extension work. (Vietnamese)
(International Potato Center, 2020-08)This brief explores the potentials and gains to be made by applying a gender perspective in agronomic research and extension work. While many people would readily acknowledge the importance of gender in any kind of agronomic research, the methods and techniques for applying the perspective are not as obvious nor easy to implement. What follows is a helpful Q&A by the interdisciplinary team who work on gender and pest and disease management in the CGIAR Research Program on Roots, Tubers and Bananas ... -

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

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