The cowpea aphid (Aphis craccivora Koch) is an economically important pest, whose feeding effects cause stunting, delayed flower initiation and yield reduction in cowpea (Vigna unguiculata L. Walp). Host plant resistance offers an alternat…
The study assessed the interactive effect of water temperature and nitrate fertilizers on growth, survival, and hatching success of eggs, embryos and larvae of African catfish Clarias gariepinus. 100 fertilized eggs of C. gariepinus were i…
Labour bottlenecks and multiple operations at the start of a cropping season often result in inadequate early weed control and subsequent poor crop performance. Therefore, there is a need to establish management practices that provide the …
Late blight is caused by Phytopthora infestans (Mont.) de Bary which establishes quickly in Solanum esculentum L. (tomato); as a result, it makes the pathogen one of the most devastating plant diseases across the world. )e control of late …
The establishment of grazing exclosures is widely practiced to restore degraded agricultural lands and forests. Here, we evaluated the potential of grazing exclosures to contribute to the “4 per 1000” initiative by analyzing the changes in…
Cassava roots, millet and cowpea leaves have short storage life thus the need for simple post-harvest handling and storage protocol to ensure prolonged availability to fully contribute toward food and nutrition security, a major challenge …
Agroforestry systems are alternative solutions for production and management of agricultural systems which may improve soil quality. In this study, we evaluated the potential of coconut Cocos nuciferabased Gliricidia (Gliricidia sepium) sy…
Grazing exclosures have been promoted as an effective and low-cost land management strategy to recover vegetation and associated functions in degraded landscapes in the tropics. While grazing exclosures can be important reservoirs of biodi…
Aims: This study tried to investigate the extent of knowledge co-production between indigenous farmers and agricultural extension in dry lands. Study Design: The study adopted survey research design where both qualitative and quantitative …
Lake Turkana fishery consists of seven endemic and 12 commercially exploited species and is the second largest producer of freshwater fish in Kenya. It supports livelihoods of approx. 300,000 people locally. The lake is managed by beach ma…
Protein sources in the diet of people living in semi-arid land of Kenya are lacking and if available it is costly to them. In terms of safe food and a healthy food supply, cowpeas (Vigna unguiculata.) are a significant source of protein, c…
Riparian forests ecosystems play significant role in biodiversity conservation and provision of ecosystem goods and services which support local livelihoods. However, riparian ecosystems are threatened by degradation attributed to anthropo…
Lake Turkana, the world’s largest desert lake, is the second largest producer of freshwater fishery in Kenya. The lake is co-managed by stakeholders’ groups called Beach Management Units (BMUs) in a co-management arrangement with the gover…
Engaging in high value potato (Solanum tuberosum) markets is one important strategy which can assist small scale farmers to increase food security and move out of poverty. Collective marketing has been identified as one of the best strateg…
Understanding the dynamics of agricultural expansion, their drivers, and interactions is critical for biodiversity conservation, ecosystem-services provision, and the future sustainability of agricultural development in Sub-Saharan Africa …
: Globally, almost 2.78 million deaths that occur annually are attributed to work-related health risks. Worldwide and, especially, in developing countries, about 20% to 50% of the workers are exposed to health risks. Fishing is an ancient …
This study sought to determine the influence of selected social-economic factors on adoption of clean seed potato by small scale farmers in Njoro Sub-County, Kenya. Clean seed potato is one of the best types of seed potato that farmers can…
Enhanced household access to credit is essential in boosting the performance of small and medium enterprises in developing nations. Despite the role played by micro-finance in enhancing access to credit among poor rural households, there i…
The social component of the environment associated mostly with human activities has significantly imposed a threat to the only life-support systems of the earth. Uganda made adjustments in its planning process to prioritize environment con…
Even though quality of seed is a major yield determinant in potato (Solanum tuberosum L.) production and global food security, inadequate availability of and access to high quality (certified) seed is a major challenge to potato producers …
This research paper addresses the hypothesis that adding yeast cultures (Saccharomyces cerevisiae) to urea-treated cereal crop residues could improve milk composition to the level of milk produced on pastures for the manufacture of Mozzare…
School absenteeism and dropout are associated with many different life-course problems. To reduce the risk for these problems it is important to gain insight into risk factors for both school absenteeism and permanent school dropout. Until…
Understanding the impacts of wood harvesting intensity on the diversity and structure of ecosystems such as mangroves is essential for defining actions for their sustainable management. We compared tree taxonomic diversity, structural diver…
Impact of oil and gas activities on quality of soil in Port Harcourt and its environments was assessed. The study evaluates levels of physicochemical parameters associated with oil and gas industry in soils of 9 locations in Port Harcourt …
Unbalanced fertilization is a problem affecting potato production in Kenya, where continuous use of nitrogen-phosphorus fertilizer (diammonium phosphate: DAP) has led to depletion of other macro and micronutrients. Hence, the need to asses…
