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 NUMERICAL RANGE OF SOME CLASSES OF OPERATORS IN HILBERT SPACES
(University of Eldoret, 2021)The numerical range of operators in Hilbert spaces has been researched by several authors. The properties of the numerical range play an important role in identifying the behaviour of operators in Hilbert spaces. It ... -
ON THE NORM OF AN ELEMENTARY OPERATOR OF FINITE LENGTH IN A 𝑪∗ALGEBRA
(Journal of Progressive Research in Mathematics(JPRM), 2018)Properties of elementary operators have been studied over the past years especially the norm aspect. Various results have been obtained on elementary operatorsof different lengths using different approaches. ... -
On the Norm of Basic Elementary Operator in a Tensor Product
(International Journal of Scientific and Innovative Mathematical Research., 2019)In this paper, we determine the norm of an elementary operator in a tensor product. More precisely, we investigate the bounds of the norm of a basic elementary operator in a tensor product. We employ the techniques of ... -
On Unitary Invariance of Some Classes of Operators in Hilbert Spaces
(Pure Mathematical Sciences, 2020)It is a known fact in operator theory that two similar operators have equal spectra but they do not necessarily have to belong to the same class of operators. However, under the stronger relation of unitary equivalence ... -
On-farm growth performance of different strains of tilapia, Oreochromis niloticus reared in earthen ponds
(Aquaculture, fish and fisheries, 2023)The growth of aquaculture sector in Kenya has been anchored on farmed Nile tilapia Oreochromis niloticus. Different strains of the species exist in Kenya with unknown qual- ity due to lack of stock improvement programmes ... -
