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 ...
Allelopathic effects of mexican sunflower [tithonia diversifolia (hemsl) a. Gray] on germination and growth of cowpea seedlings (vigna sinensis)
(2014)
Allelopathy is a common among plants. Allelopathic substances affect seed
germination, plant growth and development or even affect chlorophyll
synthesis by the plant leaves. Tithonia diversifolia contains allelochemicals
that ...
Herbicide applied to imidazolinone resistant-maize seed as a Striga control option for small-scale African farmers
(Weed Science Society of America, 2012-04)
Striga is a major constraint to food production in Africa. Most technologies developed for the eradication of Striga asiatica from the United States are not adaptable to Africa. Imazapyr and pyrithiobac coated imidazolin ...
Evaluation of Yield Advantage of Maize+ Artemisia And Maize+ Beans Intercrops In a Sub-Humid Ecozone Of Maseno, Western Kenya.
(2012)
An experiment on intercropping systems at Maseno, western Kenya sought to evaluate the yield potential of maize indifferent maize+artemisia spacing regimes in comparison to a standard maize+bean system, by identifying the ...
Carbon dioxide exchange and biomass productivity of the herbaceous layer of a managed tropical humid savanna ecosystem in western Kenya
(Oxford University Press, 2013-08-01)
Aims
Humid savannas, as a result of high precipitation amounts, are highly productive. They are also hotspots for land use change and potential sources of carbon dioxide (CO2) due to the large soil carbon (C) stocks. ...
Genetic diversity and eco-geographical distribution of Eleusine species collected from Ethiopia.
(African Journals OnLine (AJOL), 2014-02-21)
Eleusine is a small grass genus with three basic chromosome numbers (x=8, 9 and 10) and comprises of eight species including E. coracana subsp. coracana, (finger millet), which is an important subsistence crop in Africa ...
Physiological and biochemical responses of five nerica rice varieties (Oryza sativa L.) to water deficit at vegetative and reproductive stage
(2012)
Food shortage is a major problem in sub Saharan Africa as population
increases. Over 89% of Kenyans are food poor and are malnourished especially in rural
areas. NERICA (New Rice for Africa) are high yielding rainfed ...
UGbS-Flex, a novel bioinformatics pipeline for imputation-free SNP discovery in polyploids without a reference genome: finger millet as a case study
(BioMed Central, 2018-12-01)
Research on orphan crops is often hindered by a lack of genomic resources. With the advent of affordable sequencing technologies, genotyping an entire genome or, for large-genome species, a representative fraction of the ...
Responses of ecosystem carbon dioxide fluxes to soil moisture fluctuations in a moist Kenyan savanna
(Cambridge University Press, 2010-11-01)
Measurements were conducted within a fence-exclosure between February 2008 and July 2009 to investigate the influence of soil moisture on ecosystem CO₂ fluxes in a Themeda triandra-dominated grassland of a humid Kenyan ...
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 ...
