Effect of physicochemical factors and dyke on conservation of Oreochromis esculentus and Oreochromis variabilis in lake Kanyaboli, Kenya
(Maseno University, 2017)Lake Victoria witnessed mass extinction of native fish species that coincided with introductions of Lates niloticus and Oreochromis niloticus about five decades ago. Small populations of O. esculentus and O. variabilis ... -
Effects and the relationship between nitrogenous fertilizer application rates and plucking intervals on some soil quality indicators and yield of tea (Camellia Sinensis (l.) in eastern Africa tea growing regions
(Maseno University, 2018)Eastern Africa tea is grown in high rainfall areas causing high nutrients depletion through leaching and surface run-off. Nutrients are also removed with harvested crop. The depletion requires nutrients replenishment through ... -
