Impact of a Kraft Pulp and Paper Mill Effluent on Phytoplankton and Macroinvertebrates in River Nzoia, Kenya
(2015-08-21)Phytoplankton and macroinvertebrate assemblages were used to assess the impact of a kraft pulp and paper mill effluent in Kenya, on River Nzoia downstream of the discharge point in relation to changes in water quality ... -
An Ethnobotanical Study of Swamp Wetland Vegetation in Uasin Gishu County, Kenya
(2015-08-21)Ethnobotanical knowledge associated with wetland plants in Uasin Gishu County, Kenya, was assessed and docu- mented. Data on the uses of plants, their local names, and parts used were collected through semi-structured ... -
Genetic Diversity in Cultivated Sesame (Sesamum indicum L.) and Related Wild Species in East Africa
(2015-08-21)Genetic diversity of traditional sesame landraces and related wild species in East Africa remains largely unexplored. Knowing what fraction of the available genetic diversity is actually used by the farmers is of central ... -
Physiological characterization of kenyan sorghum lines for tolerance to aluminium
(2015-08-21)Eighty nine Kenyan sorghum lines were screened for tolerance to aluminium toxicity in nutrient solution. Relative net root growth; root tip aluminium content and variation in organic acid exudation were used to determine ... -
Cell membrane integrity, callose accumulation, and root growth in aluminum-stressed sorghum seedlings
(2015-08-21)Aluminum stress usually reduces plant root growth due to the accumulation of Al in specific zones of the root apex. The objectives of this study were to determine the localization of Al in the root apex of Sorghum bicolor ... -
Comparative analysis of phenotypic characterization of Kenya and Pacific Islands tarogen germplasm collections Colocasia esculenta L. (Schott)
(2015-08-21)Fifty accessions of taro germplasm collections Colocasia esculenta L. Received: 15 November, 2014 (Schott) were collected from Kenya and Pacific Islands tarogen germplasm collections. Twenty five accessions of Kenyan ... -
Genetic structure and diversity of East African taro [Colocasia esculenta (L.) Schott]
(2015-08-21)Taro [Colocasia esculenta (L) Schott] is mainly produced in Africa by small holder farmers and plays an important role in the livelihood of millions of poor people in less developed countries. The genetic diversity of ... -
Effect of wheat bran supplementation with fresh and composted agricultural wastes on the growth of Kenyan native wood ear mushrooms [Auricularia auricula (L. ex Hook.) Underw.]
(2015-08-21)Nutrient supplements and agricultural wastes used for mushroom cultivation are important in improving establishment and production of mushrooms. Agricultural wastes such as sawdust, grass, sugarcane bagasse, wheat straw ... -
Response of Leucaena leucocephala (Lam.) De Wit (Leucaena) Provenances to Aluminium in Potted Soil Experiment
(2015-08-21)Aims: To determine the level of acid or aluminium tolerance provenances in Leucaena (Leucaena leucocephala) a favourite agroforestry tree in Kenya. Study Design: The set up was a 2-factor (provenance-aluminium) experiment ... -
Gender Influence on Farmer’s Level of Involvement in Utilization and Conservation of Bambara Groundnut
(2015-08-21)Aims: To understand the role of gender on Bambara groundnut cultivation with respect to levels of farmers’ involvement in utilization and conservation in Western Kenya. Study Design: A questionnaire was administered to ... -
Farmers’ perceptions on adoption of Bambara nut production as a food security crop in Kakamega county, Kenya
(2015-08-21)This study was conducted between April and December 2011 to examine perception of smallholder farmers in four districts of Kakamega County, Kenya in adoption of Bambara nut production as food security crop. The study was ... -
Mycorrhizal Development and Phosphorus Concentration in selected Kenyan Sorghum Cultivars
(2015-08-19)This study was carried out on sorghum genotypes that exhibited significant difference in growth and production on P-deficient soils. The objective was to find out if the genotypes developed different levels of mycorrhizal ... -
Cell membrane integrity, callose accumulation, and root growth in aluminum-stressed sorghum seedlings
(2015-08-19)Aluminum stress usually reduces plant root growth due to the accumulation of Al in specific zones of the root apex. The objectives of this study were to determine the localization of Al in the root apex of Sorghum bicolor ... -
Genetic relationship between sesame (Sesamum indicum L.) and related wild species based on chromosome counts and isozyme markers
(2015-08-19)Sesame is an orphan crop with little research attention in Kenya. Genetic relationship between cultivated sesame and related wild species in Kenya is not well known. The objective of this study was to determine genetic ... -
Combining ability of some sorghum lines for dry lands and sub-humid environments of East Africa
(2015-08-19)Sorghum (Sorghum bicolor L. Moench) is a major food crop grown in dry lands and sub-humid areas of East Africa. A study was conducted between 2010 to 2012 in dry lands (Miwaleni, Kiboko) and sub- humid (Ukiriguru) ... -
Response of selected sorghum (Sorghum bicolor L. Moench) germplasm to aluminium stress
(2015-08-19)Sorghum (Sorghum bicolor L. (Moench) is an important food security crop in sub-Saharan Africa. Its production on acid soils is constrained by aluminium (Al) stress, which primarily interferes with root growth. Sorghum ...
