(2015-08-21)he impact of Rhipicephalus appendiculatus tick presence (exposure) on Theileria parva infection seroprevalence (outcome) on a farm was assessed in a group of cattle using population attributable fractions (PAF). The ... -
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 ... -
Development of maize single cross hybrids for tolerance to low phosphorus
(2015-08-21)Low available phosphorus (P) is one of the major hindrances to maize (Zea mays L.) productivity in acid soils. The objectives of this study were to: (1) develop P-efficient maize inbred lines, (2) develop single cross ... -
Effects of lime, phosphorus and rhizobia on Sesbania sesban performance in a Western Kenyan acid soil
(2015-07-21)Aluminium (Al) toxicity, phosphorus (P) deficiency and low rhizobia populations limit Sesbania (Sesbania sesban) performance in tropical acid soils. The study determined the i) indigenous rhizobia populations that nodulate ... -
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 ... -
