Leguminous cover crops differentially affect maize yields in three contrasting soil types of Kakamega, Western Kenya
(Journal of Agriculture and Rural Development in the Tropics and Subtropics (JARTS), 2011)Maize production in smallholder farming systems in Kenya is largely limited by low soil fertility. As mineral fertilizer is expensive, green manuring using leguminous cover crops could be an alternative strategy for farmers ... -
Potential of Controlling Common Bean Insect Pests (Bean Stem Maggot (Ophiomyia phaseoli), Ootheca (Ootheca bennigseni) and Aphids (Aphis fabae)) Using Agronomic, Biological and Botanical Practices in Field
(Scientific Research Publishing, 2015-05-22)Common bean production in Africa suffers from different constrains. The main damage is caused by insect pest infestations in the field. The most common insects pests which attack common bean in the field are the bean ... -
Extrapolations on the Use of Rhizobium Inoculants Supplemented with Phosphorus (P) and Potassium (K) on Growth and Nutrition of Legumes
(Scientific Research Publishing, 2014-10-22)Land scarcity and poor farming management practices has resulted in to intensive agriculture which rendered most of the soil in sub Saharan Africa depleted in essential plant nutrients. High prices of chemical fertilizer ... -
Effects of Rhizobium inoculation and Supplementation with P and K, on Growth, Leaf chlorophyll content and Nitrogen Fixation of Bush bean varieties
(American Journal of Research Communication, 2014)Low crop productivity is a general problem facing most farming systems in sub-Saharan Africa (SSA). These low yields are pronounced in grain legumes and are often associated with declining soil fertility and reduced ... -
Invasive weeds with pesticidal properties as potential new crops
(Elsevier, 2017-12-30)Plants with pesticidal properties have been investigated for decades as alternatives to synthetics, but only a handful have been commercialised and developed as non-food cash crops. One of the reasons why pesticidal plants ... -
Effect of Rhizobium inoculation and supplementation with phosphorus and potassium on growth and total leaf chlorophyll (Chl) content of bush bean Phaseolus vulgaris, L.
(Scientific Research Publishing, 2014-12-09)The study was conducted to investigate the effect of Rhizobium inoculation and supplementation of phosphorus and potassium on growth and total leaf chlorophyll content to the three released bush bean varieties in ... -
Prospective Bioactive Compounds from Vernonia amygdalina, Lippia javanica, Dysphania ambrosioides and Tithonia diversifolia in Controlling Legume Insect Pests
(Scientific Research Publishing, 2014-10-22)Synthetic insecticides are widely known to control insect pest, but due to high operational cost, environmental pollution, toxicity to humans, harmful effect on non-target organisms and the de velopment of insect resistance ... -
Fertility management for maize cultivation in some soils of Western Kenya
(Elsevier, 2011-12-01)Soil fertility loss in Western Kenya is exacerbated by inadequate nutrient management and causes reduced maize yields. Given the diversity of soil types, cropping seasons, and the resource endowment of farmers, the magnitude ... -
Isolation and characterization of nitrogen fixing rhizobia from cultivated and uncultivated soils of northern Tanzania
(Scientific Research Publishing, 2014-12-18)Soil bacteria1 called rhizobia are gram-negative capable to colonize the soil immediately surrounding roots under the influence of the plant “rhizosphere” and reduce atmospheric nitrogen into the form available to plants ... -
Drivers of increased soil erosion in East Africa’s agro-pastoral systems: changing interactions between the social, economic and natural domains
(Springer Berlin Heidelberg, 19-06-18)Increased soil erosion is one of the main drivers of land degradation in East Africa’s agricultural and pastoral landscapes. This wicked problem is rooted in historic disruptions to co-adapted agro-pastoral systems. ... -
Impacts of Synthetic and Botanical Pesticides on Beneficial Insects
(Scientific Research Publishing, 2016-06-17)Sustainable methods to control insect pests that affect crop yield have become a great challenge to mainly smallholder farmers. Beneficial insects in agricultural fields play an important role in natural pest control and ... -
Extracts from field margin weeds provide economically viable and environmentally benign pest control compared to synthetic pesticides
(Public Library of Science, 2015-11-23)Plants with pesticidal properties have been investigated for decades as alternatives to synthetics, but most progress has been shown in the laboratory. Consequently, research on pesticidal plants is failing to address gaps ... -
Wastewater treatment for reuse in urban agriculture; the case of Moshi Municipality, Tanzania
(Pergamon, 2014-01-01)Urban agriculture is practiced by dwellers as an adaptive response to improve their food security, household income, create informal employment and diversify their livelihood through sales of surplus produce or savings. ... -
First Report of the Co‑occurrence of Cylindrospermopsin, Nodularin and Microcystins in the Freshwaters of Lake Victoria, Tanzania
(Scientific Research Publishing, 2020-07-26)Abstract There is a global concern regarding the increase of cyanotoxins in freshwater and their potential effects on human health. The existence of multiple toxins in freshwater can result in an increased risk of their ... -
Electrocatalytic reduction of CO2 gas at Sn based gas diffusion electrode
(Elsevier B.V., 2011-07-01)The tin (Sn) based gas diffusion electrode was fabricated and applied for CO2 electroreduction in a zero gap cell. The fabrication was done by electrodeposition from a simple citrateechloride plating solution by chrono ... -
Prevalence of chronic obstructive pulmonary disease and associated factors among smallholder fish vendors along coastal areas in Tanzania
(BMC Pulmonary Medicine, 2023-08-02)Background In Tanzania little is known about how the respiratory system of small-holder fish vendors is affected by occupational exposure to biomass smoke and other associated factors. This study assessed the prevalence ... -
Conceptualization of groundwater-surface water interaction with evidence from environmental isotopes and hydrogeochemistry in lake Babati Basin in Northern Tanzania
(Elsevier, 2023-05)The holistic management of water resources is attainable with evidence-based planning constructed on reliable hydrological information. However, data paucity, especially in sub-Saharan Africa, leads to a significant knowledge ... -
Modeling and optimization of trivalent arsenic removal from wastewater using activated carbon produced from maize plant biomass: a multivariate experimental design approach
(Springer Nature Limited, 2023-06-24)Globally, both industrialized and developing nations struggle with the issue of water pollution due to heavy metals. Human life depends on water, and when it is contaminated with dangerous heavy metals like arsenic, people’s ... -
