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 ...
Genetic diversity and population structure of Striga hermonthica populations from Kenya and Nigeria
(2017-10-01)
Striga hermonthica is a parasitic weed that poses a serious threat to the production of economically important cereals in sub‐Saharan Africa. The existence of genetic diversity within and between S. hermonthica populations ...
Evaluation of different improved upland rice varieties for low soil nitrogen adaptability
(2015)
Scarcity of nitrogen fertilizer is a major constraint to rice production particularly
in developing countries. Low soil fertility prevalent in farmer's fields has led to low rice yields
and the ever escalating fertilizer ...
Phytotoxic effect of selected crude plant extracts on soil-borne fungi of common bean
(African Crop Science Society (Uganda), 2010)
Common bean (Phaseolus vulgaris L.) is an important food and cash crop particularly in Eastern, Southern and Great lake region. The efficacy of water based crude plant extracts of Neem (Azadirachta indica), Mexican marigold ...
Community Tree Seedling Production in Maseno Division, Kenya
(IJRIAS), 2019-07)
Forests and trees are important natural resources
globally. The reduction of forests and tree cover has occasioned
the loss of biodiversity, wildlife habitat, ecosystem integrity;
increased climate variability and reduced ...
Allelopathic potential of mexican sunflower [tithonia diversifolia (hemsl) a. Gray] on germination and growth of cowpea seedlings (vigna sinensis l.)
(2015)
Invasive plant species when introduced into new environments may result into a number of
ecological problems (Howard et al., 2000). They may influence other species through
pathways such as allelopathy or phytotoxicity ...
Bacteriological and Physicochemical characterisation of AoraLoko Stream water,Maseno kenya
(AESS Publications, 2017)
Safety and quality of drinking water is an important aspect in public health. Water
pollution is one main cause of worldwide diseases and death. Human activities around
water catchment areas contribute to some level ...
Chlorophyll fluorescence, protein and chlorophyll content of three nerica rainfed rice varieties under varying irrigation regimes
(2010)
Water deficit affects growth and development of rainfed rice leading to a
considerable yield reduction or crop failure. Although the rice crop is susceptible to water
deficit, there is a marked genotypic variation in ...
Stem bark extracts of Erythrina excelsa (Baker) and their biological activities
(2016)
The species is known from Southern Nyanza, Migori in Kenya. The extraction of the stem bark was done
sequentially using organic solvents starting with the least polar; n-hexane then dichloromethane, ethyl
acetate and ...
