Mechanistic understanding of iron toxicity tolerance in contrasting rice varieties from Africa: 1. Morpho-physiological and biochemical responses
(CSIRO PUBLISHING, 2019-01-21)Iron (Fe) is a fundamental element involved in various plant metabolic processes. However, when Fe uptake is excessive, it becomes toxic to the plant and disrupts cellular homeostasis. The aim of this study was to determine ... -
Mechanistic understanding of iron toxicity tolerance in contrasting rice varieties from Africa: 1. Morpho-physiological and biochemical responses
(CSIRO PUBLISHING, 2018)Iron (Fe) is a fundamental element involved in various plant metabolic processes. However, when Fe uptake is excessive, it becomes toxic to the plant and disrupts cellular homeostasis. The aim of this study was to ... -

Moisture content and the longevity of seeds of six Euphorbia species in open storage
(International Seed Testing Association, 2009-07-01)Seeds from six Kenyan Euphorbia species were placed into experimental storage under open conditions (i.e. not hermetically sealed) over a range of relative humidities (between 25 and 75%) at 45°C. Viability during storage ... -
Molecular Breeding for Iron Toxicity Tolerance in Rice ( Oryza sativa L.)
(John Wiley & Sons, Ltd., 2023-11-03)Rice consumption is on an upward trajectory worldwide based on changes in eating habits, population growth, and ease of cooking and yet rice production is not keeping up. There are many constraints including abiotic stresses ... -
Morphological characterization of some wild and cultivated watermelon (Citrullus sp.) accessions in Kenya
(ARPN Journal of Agricultural and Biological Science, 2009)Genetic diversity and relatedness were assessed among three most common commercial watermelon cultivars in Kenya; one newly introduced commercial cultivar from the U.S., one Kenyan landrace and one wild (Citrullus colocynthis) ... -
Morphological, biochemical and molecular characterization of Xanthomonas campestris pv. vesicatoria of African nightshades (Solanum scabrum Mill.)
(2016)African nightshade (Solanum scabrum Mill.) is one important vegetable in terms of food security and nutritional balance. The vegetable is usually medicinal and also a source of income to many small scale farmers in ... -
Multiple-bean varieties as a strategy for minimizing production risk and enhancing yield stability in smallholder systems

New evaluation of Alternaria brassicicola isolates against Striga hermonthica seeds emergence on maize in Kenya
(JRWS, 2021)Striga hermonthica (Del.) Benth is also known as witchweed, is a highly noxious parasite of cereal in Sub- Saharan Africa leading to enormous economic losses of above 7 billion US$ yearly. Some of the suggested control ... -
Non-host resistance to the finger millet blast pathogen Magnaporthe oryzae is modulated by a resistance response to PWL1 and PWL2 in Eragrostis curvula but not in related Chloridoid species
(2023-05-28)Magnaporthe oryzae, a devastating pathogen of finger millet (Eleusine coracana), secretes effector molecules during infection to manipulate host immunity. This study determined the presence of avirulence effector genes ... -
Participatory consumer evaluation of twelve sweetpotato varieties in Kenya
(African Journals OnLine (AJOL), 2010)Eleven improved sweetpotato varieties; “Kemb10, SPK004, Mugande, Namaswakhe, K117, Polista, Bungoma, Odinga, 292-H-12, Zapallo” and “Nyathi Odiewo (improved) ”, were tested against four popular farmer varieties; “Nyathi ... -
Participatory evaluation of integrated pest and soil fertility management options using ordered categorical data analysis
(Elsevier, 2010-06-01)Maize is becoming the major food crop around Lake Victoria. Major constraints to its production are Striga, stem borer, and declining soil fertility. Innovative integrated technologies have been developed: the ‘push–pull’ ... -
Participatory selection of sweet potato (Ipomoea batatas (L.) Lam.) cultivars using mother and baby trial in Western Kenya
(ISHS Acta Horticulturae 911, 2009-08-31)Sweet potato (Ipomoea batatas (L.) Lam) is a drought tolerant food security crop. Western Kenya accounts for 60% of the national production. Intensive production is constrained by lack of improved high yielding cultivars ... -
Physiological and biochemical responses of five nerica rice varieties (Oryza sativa L.) to water deficit at vegetative and reproductive stage
