(Asian Network for Scientific Information, 2007)Laboratory and greenhouse experiments were conducted to determine the allelopathic activity of sunflower (Helianthus annuus) on seed germination, seedling growth, flowering and nodulation of bambara groundnut (Vigna ... -
Investigation of heavy metal hazards Status and their potential health risks in vegetables Irrigated with treated wastewater in Oodi gardens
(Springer, 2017-10-11)This study was conducted in Oodi Village, Botswana to investigate human health risk associated with heavy metals: Mn, Fe, Cu, Ni and Zn intake via consumption of contaminated locally grown vegetable: Spinacia oleracea L. ... -
Prediction of animal population dynamics with a focus on smallholder pig breeding establishments #
(Botswana University of Agriculture and Natural Resources, 2012)Botswana government has made efforts to diversify agriculture and pig production has been identified as one avenue to achieve this diversification in the livestock industry. It is important that farmers are encouraged to ... -
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 ... -
Phosphorus levels in shoots of Bambara groundnut in Botswana soils
(Taylor & Francis, 2002)The critical phosphorus (P) concentration and range of bambara groundnut (Vigna subterranea) plants were determined from a sand culture experiment at Botswana College of Agriculture. Twelve P levels (0.207–159 mg P pot−1) ... -
Potassium→ammonium exchange of two benchmark soils from Botswana and its implication for nitrogen economy of the soils
(Taylor & Francis, 2014)Ion exchange preferences for NH4+ and K+ by soil exchanger surface can greatly affect the NO3− leaching into groundwater and nitrogen-use efficiency in agricultural production. Since NH4+ and K+ salts are usually applied ... -
Ngoro: an indigenous, sustainable and profitable soil, water and nutrient conservation system in Tanzania for sloping land
(Elservier, 2004)The Matengo people, in SW Tanzania, developed the ngoro conservation system several hundred years ago and it is a very effective indigenous manual cultivation practice for steep slopes. It deserves wider recognition and ... -
Influence of flooding on bambara groundnut (Vigna subterranea L.) germination: Effect of temperature, duration and timing
(Academic Journals, 2009)To evaluate the response of bambara groundnut seeds to flooding stress a laboratory study (experiment 1) and a greenhouse study (experiment 2) were conducted. In the laboratory study seeds of a brown-coloured local bambara ... -
Farmers’ knowledge, perceptions and management of vegetable pests and diseases in Botswana
(Elservier, 2008)Vegetable farmers’ knowledge and perceptions of pests, diseases and pest management practices were investigated by interviewing 112 growers in Botswana between April and June 2004. Most of the farmers grew brassicae crops, ... -
Farmers’ knowledge in the cropping systems of Northern KwaZulu-Natal, South Africa: Current challenges and solution for sustainable future food production
(Academic Journals, 2009)Most African farmers involved in food production in South Africa; practice peasant farming for consumption and for retail sale in the informal market, local communities and street corners in the cities. These farmers are ... -
Experimental and numerical evaluation of analytical volume balance model for soil water dynamics under drip irrigation
(Soil Science Society of America, 2003)The interpretation and subsequent modeling of soil water dynamics in presence of active plant uptake remains a challenge. Despite many simplifying assumptions in their development, analytical models offer simple and easy ... -
Elephant impact on shoot distribution on trees and on rebrowsing by smaller browsers
(Elservier, 2006-10)In order to determine the effects of a megaherbivore, the African elephant (Loxodonta africana) on browse available for mesoherbivores, we assessed the vertical distribution of shoots (< 6 mm in diameter) on trees with ... -
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 ... -
Effects of combined apertures on the magnitudes of electric coupling coefficients of combline resonators
(IOP Publishing, 2014)The effects of differently positioned and combined apertures on the magnitudes of electric coupling coefficients of two identical combline resonators are analysed. Coupling coefficient, k-vertical symmetry provides greater ... -
Effect of control plot density, control plot arrangement, and assumption of random or fixed effects on nonreplicated experiments for germplasm screening using spatial models
(Crop Science Society of America, 2005)Early generation selection experiments typically involve several hundred to thousands of lines. Various systematic and statistical techniques have been developed to increase effectiveness and efficiencies in such experiments, ... -
Documentation of indigenous knowledge and best-bet practices on the use of animals and plants for sustainable natural resources management in Botswana
(Botswana University of Agriculture and Natural Resources, 2014)A study was carried out to document indigenous knowledge (IK) and practice on use of animals and plants, and best-bet practices (BBPs) during Phase I (2003-2004) of the Desert Margins Programme (DMP), whose overall objective ... -
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 ... -
