OCCURRENCE AND ABUNDANCE OF INSECT PESTS ON AFRICAN INDIGENOUS VEGETABLE VARIETIES UNDER DIFFERENT FERTILIZER TREATMENTS AND SEASONS IN KITALE, KENYA
(University of Eldoret, 2016)African indigenous vegetables (AIVs) once wild are now among the plants domesticated and are increasingly popular in peoples’ diet. Due to this, they have commercial potential and farmers use fertilizers and improved ... -
OCCURRENCE AND MANAGEMENT OF ALTERNARIA LEAF SPOT IN SPINACH USING EXTRACTS FROM GINGER AND TUMERIC PLANTS
(University of Eldoret, 2019)Spinach (Spinacia oleracea) is an economically important vegetable crop in Kenya cultivated by small-scale farmers for domestic consumption. Alternaria leaf spot caused by Alternaria alternata is one of the diseases of ... -
The Occurrence and Pathological Characterization of Rust Causing Fungi of Brachiaria Grass in Kenya
(African Journal of Education Science and Technology, 2019)Brachiaria grass is one of the most important grasses distributed throughout the tropics especially in Africa. The quality of forage yields and biomass of brachiaria is negatively affected by diseases among which leaf spot, ... -
OCCURRENCE OF COMMON BACTERIAL BLIGHT CAUSED BY Xanthomonas axonopodis pv. phaseoli ON COMMON BEAN AND THE INFLUENCE OF DIFFERENT FACTORS ON IT’S INCIDENCE IN UASIN GISHU COUNTY
(Int. J. Adv. Res., 2019)Beans (Phaseolus vulgaris) is a popular legume crop in Kenya, ranking first among the legumes in importance. The production of this crop in Kenya has not kept pace with the demand. Among the main causes for poor ... -
ON ALMOST SIMILARITY AND SOME CLASSES OF OPERATORS IN HILBERT SPACES
(University of Eldoret, 2021)Similarity is a recent area of study on classes of operators in Hilbert spaces. The study of operators, under similarity and quasisimilarity concepts, motivated researchers to extend their research to almost similarity ... -
On almost similarity results on partial isometrics, 𝛉- operators and posinormal operators
(International Journal of Statistics and Applied Mathematics, 2021-06)It is pre-eminent that equality of spectra is realized when the two given operators are unitarily equivalent or similar but not when they are almost similar. Also, projections which are 𝛼-almost similar, demonstrate ... -
ON CLASSIFICATION OF PERMUTATIONS
(Asia Pac Journal, 2020-03)Some researchers in combinatorics have developed permutation algorithms using different approaches. We contribute to this area by developing a formula for generating permutations whereby, starting with an identity ... -
