Assessing the contribution of dolichos bean (Lablab purpureus L. (sweet)) to food security in a changing climate in Kenya
(2022)Lablab pupureus (L.), is a multipurpose drought tolerant legume which is considered as a minor crop in Kenya, hence, it is underutilized. In Kenya there are few known Lablab genotypes for specific environments. Choice of ... -
Determination of the effect of fermentation on the rate of plant nutrient release from plant tissues.
(2022)The use of fermented plant extracts (FPE) as a top dress in crop production is a natural process that can provide plant nutrients and suppress diseases. However, there is scanty information on the use of plant extracts ... -
A community-based evaluation of population growth and agro-pastoralist resilience in Sub-Saharan drylands
(2019-02)Abstract Human population growth is considered together with climate warming as major driver of change in Sub-Saharan Africa. Research on the implications of increased population densities often utilises community knowledge ... -
ASSESSMENT OF PRODUCTION CONSTRAINTS AND CONTRIBUTION OF AVOCADO TO FOOD SECURITY AND INCOME IN THE MOUNT KENYA REGION, KENYA
(2023)ABSTRACT Avocado (Persea americana Mill.) belongs to the family Lauraceae and it is an important crop to rural communities and economies in Kenya. Currently, avocado is grown in several agro ecological zones mainly ... -
Assessment of genetic diversity of Kenyan dolichos bean (Lablab purpureus L. sweet) using simple sequence repeat (SSR) markers.
(2016-01)The level of genetic relatedness or dissimilarity of Lablab genotypes used by growers in different regions in Kenya has not been determined. In this study, ninety six (96) Lablab accessions collected from various parts ... -
Assessment of phenotypic diversity of Kenyan dolichos bean (Lablab purpureus L. sweet) germplasm based on morphological markers
(2017)In Kenya, lack of phenotypic diversity assessment of Lablab has hindered its improvement. It is common to find that morphologically similar cultivars do not bear the same name while cultivars bearing the same name may not ... -
Assessing the efficacy of wild basil (Ocimum americanum L. (Walp)) in the management of cowpea weevil (Callosobruchus maculatus)
(2022-02-28)Cowpea (Vigna unguiculata (L.) Walp) belongs to the family Fabaceae and is one of the pulses that suffer postharvest losses greatly. The major insect that attacks stored cowpea seed in Kenya is the cowpea weevil (Callosobruchus ... -
Investigation of noradrenergic receptor system in anti-nociception using formalin test in the naked mole rat (Heterocephalus glaber).
(Elsevier Ltd., 2023-10-23)The naked mole rat (NMR) is a rodent that has gained importance as a biomedical research model for various conditions like hypoxic brain injury, cancer and nociception. This study was designed to investigate possible ... -
The effects of clonidine and yohimbine in the tail flick and hot plate tests in the naked mole rat (Heterocephalus glaber).
(Springer Nature, 2021-05-17)Objective: The naked mole rat (NMR) (Heterocephalus glaber) is increasingly considered an important biomedical research model for various conditions like hypoxic brain injury, cancer and nociception. This study was designed ... -
Evaluation of drought tolerance in mutant Kenyan bread wheat (Triticum aestivum L.) using in vitro techniques
(INNSPUB, 2016-08-31)Wheat (Triticum aestivum L) is widely cultivated as a small-grain cereal. In Kenya, it is ranked second after maize in its contribution towards food security. Biotic stress conditions such as drought cause extensive losses ... -
Effects of entomopathogenic fungus and spider plant intercrop in control of onion thrips and iris yellow spot virus
(INNSPUB, 2018-06-30)Iris yellow spot virus (IYSV) is a major constraint to bulb onions production in Kenya. In search for alternative to synthetic insecticide, field experiments were conducted for two cropping seasons to evaluate the effectiveness ... -
In Vitro Bioactivities of Commonly Consumed Cereal, Vegetable, and Legume Seeds as Related to Their Bioactive Components: An Untargeted Metabolomics Approach Using UHPLC–QTOF-MS2.
(MDPI, 2023-07-27)We conducted a comprehensive evaluation of the antioxidant, anti-obesity, anti-diabetic, and anti-glycation activities associated with the consumption of broccoli, red cabbage, alfalfa, and buckwheat seeds. Additionally, ... -
Effects of induced mutagenesis and single backcrossing on agronomic traits of wheat (Triticum L.).
(2014-07-12)Induced mutagenesis has been extensively used to improve main crop species, particularly cereals including barley (Hordeum vulgare L).The main strategy in mutation-based breeding is to upgrade ... -
Optimization of manufacturing conditions of the new purple leafed Kenyan teas (TRFK 306) – maceration style and withering duration
(2018)Purple tea in Kenya, TRFK 306, has received great attention due to its perceived health benefits though how it should be optimally manufactured has not been researched on exhaustively. The current study investigated ... -
Integrating Cordia Africana Trees on Farms Differentially Improves Soil Properties in Small Holder Farms in Kirinyaga County, Kenya
(2023-08-08)Tree-based solutions are more efficient in nutrient cycling in farming systems and hence ideally suited for impoverished farmers experiencing food insecurity. Agroforestry trees have a positive effect on soil fertility ... -
SEASONAL DYNAMICS AND ALTERNATE HOSTS OF THRIPS TRANSMITTED Iris yellow spot virus IN KENYA
(African Crop Science Society, 2018)Thrips-transmitted Iris yellow spot virus (IYSV) (Family Tospoviridae, Genus Orthotospovirus) is a major constraint to onion (Allium cepa L.) production in Kenya. Determining seasonal patterns of the vector and alternate ... -
Evaluation of drought tolerance in some Kenyan bread wheat (Triticum Aestivum L.) at seedling stage
(2019-11-02)Wheat (Triticum aestivum L) is the second largest contributor to food security in Kenya. However, water deficiency retards plant growth and productivity significantly. With few drought tolerant varieties available, there ... -
Identification of Maize Leaf Diseases Based On AlexNet and ResNet50 Convolutional Neural Networks
(2023-08-30)Maize crop protection is crucial for global food security, requiring accurate disease identification. In Kenya, farmers rely on subjective visual analysis of symptomatic leaves, which is time-consuming and prone to ... -
