(Cambridge University Press, 2012-12-01)The variation in demographic parameters (namely survival and fecundity, intrinsic rate of natural increase pre-reproductive period and relative growth rate) was used to assess the resistance of cowpea landraces (namely ... -
Physicochemical properties of butter made from camel milk
(Elservier, 2013)The making of butter from camel milk using a traditional churning method and the physicochemical properties of the butter were assessed. Camel milk was obtained from pastorally managed camels in the Erer valley, eastern ... -
Current approaches to Alectra vogelii control in cowpea.
(African Journals Online, 2013-03-14)Alectra vogelii (L.) Benth is a parasitic weed in the family Scrophulariaceae that causes substantial damage by attaching onto the cowpea, Vigna unguiculata (L. Walp.) plant and tapping nutrients from it. Cowpea is one of ... -
Determination and source apportionment of selected heavy metals in aerosol samples collected from Sebele
(Science Publication, 2013-05-17)Bush fires and dust in the dry winter months establish moderately high background levels of aerosols. Emissions into the atmosphere by copper mines, coal mines and vehicular emissions are all possible sources of air pollution ... -
Grazing management systems and their effects on savanna ecosystem dynamics: A review
(Academic Journals, 2013-06)The savanna ecosystems support livestock production and livelihood of pastoral communities. The degradation of savanna ecosystems due to overgrazing had lead government commercializing communal grazing land to privately ... -
The Efficacy of Micronutrient-Fortified Sorghum Meal in Improving the Immune Status of HIV-Positive Adults.
(Karger Publishers, 2013-06-20)Background: Micronutrient deficiencies are common and compound the effects of human immunodeficiency virus (HIV) infection in Africa. Nutritional interventions, particularly vitamin A supplementation, may improve immune ... -
Factors Influencing Methane (CH4) and Nitrous oxide (N2O) Emissions from Soils: A Review
(International Journal of Forest, Soil and Erosion, 2013-08)Methane (CH4 ) and nitrous oxide (N2O) are the two most important non-carbon dioxide (CO2 ) greenhouse gases (GHGs) that play a critical role in shaping the global climate. Their concentrations in the atmosphere have been ... -
Evaluating the Growth Response of Cassia abbreviata oliv. Seedlings to Growing Mediain Botswana

Development and application of modern agricultural biotechnology in Botswana: The potentials, opportunities and challenges
(GM Crops & Food, 2014)In Botswana, approximately 40% of the population live in rural areas and derive most of their livelihood from agriculture by keeping livestock and practising arable farming. Due to the nature of their farming practises livestock ... -
Effects of planting date and transgenic maize hybrids on Fusarium ear rot severity at Hoytville and Wooster, Ohio, USA
(Botswana University of Agriculture and Natural Resources, 2014)A three year study was conducted at Hoytville and Wooster, Ohio from 2006 to 2008 to find out how sequential planting of transgenic and non-transgenic maize influence Fusarium ear rot of maize. Maize hybrids with different ... -
Drought responsive genes and their functional terms identified by GS FLX Pyro sequencing in maize
(Crea Journals, 2014)Drought stress is a major challenge for the production of maize (Zea mays L), leading to reduced growth of aerial parts and, to a large extent, reproductive stages of development. We applied the 454 GS FLX titanium platform ... -
