Utilization of the earthworm, Eisenia fetida (Sevigny, 1826) as an alternative protein source in fish feeds processing
(Wiley. Aquaculture Research, 2019)Use of fish meal in aquaculture is gradually becoming unsustainable due to competition, cost and ecological challenges hence the need to expand the alternative protein sources. The earthworm, Eisenia fetida is among the ... -
Efficiency of pumpkin (Cucurbita pepo), sweet wormwood (Artemisia annua) and amaranth (Amaranthus dubius) in removing nutrients from a smallscale recirculating aquaponic system
(Aquaculture International Research Journal, 2019)In aquaponic systems, plants absorb dissolved nutrients from aquaculture wastewater for their growth. The removal of nutrients allows reuse of water and minimises wastewater discharge to the surrounding environment. This ... -
Effects of Deficit Irrigation and Mulch on Yield and Quality of Potato Crop
(African Journal of Education, Science and Technology, 2018, 2018)Field trials were carried out at Uswo location, located in North Rift part of Kenya during March 2016-July 2016 growing seasons. The main objective was to determine the yield and quality responses of potato crop to deficit ... -
Factors influencing indigenous community practices in curbing postharvest losses: A study of Kipsaraman Division, Baringo County, Kenya
(International Journal of Agriculture and Environmental Research, 2019)"Hunger, malnutrition, and poverty remain stubbornly persistent in sub-Sahara Africa especially among poor rural households where postharvest losses are observed, thus increasing levels of hunger and poverty. In this ... -
Effective Adoption of Striga Control Technologies in Maize by Association and Non-Association Farmers in Bungoma County
(Kenya,African Journal of Education, Science and Technology,2018, 2018)Striga species also known as witchweeds decimate agriculture in most parts of Africa, attacking the major cereal grains and legumes, and halving the already very low yields of subsistence farmers in Kenya, Bungoma County ... -
Assessment of Genetic Variability Estimates of selected Traits in Irish Potato Mutants
(Journal of Advances in Biology & Biotechnology, 2018)For an effective potato breeding strategy, knowledge of the genetic parameters of traits, such as heritabilities and genetic correlations are essential, hence the need to assess the genetic variability estimates of ... -
Measuring Consumer interest in Sorghum Composite Flours in Western Kenya.
(International Journal of Scientific and Research Publications, 2019)In western Kenya, sorghum (Sorghum bicolor) remains an important crop for rural food and nutrition security. Sorghum is a rich source of various phytochemicals including tannins, phenolic acids, anthocyanins and phytosterols ... -
EVALUATION OF KENYAN DOLICHOS (Lablab purpureus L.) GENOTYPES FOR RESISTANCE TO LEGUME POD BORERS (Maruca vitrata and Helicoverpa armigera) USING MORPHOLOGICAL AND BIOCHEMICAL MARKERS
(2018)Dolichos (lablab purpureus) is an important highly proteinous human food and animal feeds. It is grown in the tropics and subtropics of the world. Common production constraints of Dolichos lablab are low yields, poor cooking ... -
INTROGRESION OF MAIZE STREAK VIRUS TOLERANCE INTO SELECTED PHOSPHORUS EFFICIENT AND ALUMINIUM TOLERANT KENYAN MAIZE LINES
(2018)Maize is one of the most important cereals produced globally. It has a number of uses such as the production of feed, food, as well as industrial products. However, its productivity is limited by both biotic and abiotic ... -
DIVERSITY OF ELITE KENYAN BREAD WHEAT MUTANT LINES IN STEM RUST (Puccinia graminis f. sp. tritici) RESISTANCE
(2018)Stem rust caused by Puccinia graminis f. sp. tritici is a major constraint to wheat production in Kenya. The re-emergence of a new fungal race Ug99 and its variants have caused devastating losses to wheat production since ... -
EVALUATION OF CHICKPEA GENOTYPES FOR RESISTANCE TO ASCOCHYTA BLIGHT IN RIFT VALLEY, KENYA
