Increasing imazapyr-resistant maize yield by increasing plant density under natural Striga hermonthica infestation
(ScienceHuß, 2010)Maize (Zea mays L.) is one of the most important crops in East Africa serving both as a staple food and cash crop to millions of people. As a vegetable, it is produced as green maize cobs, sweet corn or baby corn. Yields ... -
Integrated management of Striga hermonthica, stemborers, and declining soil fertility in western Kenya
(Elsevier, 2008-05-10)Striga hermonthica (Delile) Benth., stemborers, and declining soil fertility are serious threats to sustainable food production in the Lake Victoria zone of Kenya. To address these constraints, promising integrated crop ... -
Interactive influence of rainfall manipulation and livestock grazing on species diversity of the herbaceous layer community in a humid savannah in Kenya
(Elsevier, 2019)Changes in rainfall regime and grazing pressure affect vegetation composition and diversity with ecological implications for savannahs. The savannah in East Africa has experienced increased livestock grazing and rainfall ... -
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 ... -
Mechanistic understanding of iron toxicity tolerance in contrasting rice varieties from Africa: 2. Root oxidation ability and oxidative stress control
(CSIRO PUBLISHING, 2020-02-03)To enhance breeding efficiency for iron (Fe) toxicity tolerance and boost lowland rice production in sub-Saharan Africa, we have characterised the morphological, physiological and biochemical responses of contrasting rice ... -
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 ... -
