Foraging strategies of sheep and goats under semi-intensive management in Botswana
(Bureau for Scientific Publications, 2004)Diet selection of sheep and goats was determined seasonally using the microhistological technique to assess their trophic diversities, diet overlapping and preferences between the two species. The trophic diversities of ... -
Modeling the dynamics of tuberculosis transmission in children and adults
(Science Publications, 2012)Abstract: Problem statement: The fight Against Tuberculosis (TB) has mainly focused on the adult population because children were perceived to pose a very low risk in TB transmission. This assumption ignores the potential ... -
Economics of smallholder sorghum and maize production systems in Botswana: a comparative analysis
(Journal of Agriculture in the Tropics and Subtropics, 1997-10)Sorghum and maize, the predominant crops of smallholder farmers in Botswana, compete for the same limited resources of the farmers. Unfortunately very little is known about their relative economic efficiency. Using farm-level ... -
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 ... -
Enhancing quality of tertiary education through programme accreditation: a case of Botswana
(Elservier, 2010)This study presents narrated facts about the complex nature of accrediting tertiary education programs in Botswana. Content analysis procedures were employed to characterise the accreditation process experienced by local ... -
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 ... -
Effectiveness of field practical training for competence acquisition among students of Botswana College of Agriculture
(Academic Journals, 2011-02-18)Field practical training is a requirement for all students who enrol in any program in the Botswana College of Agriculture, as it has been discovered that, experiential learning complements theoretical classroom teaching. ... -
Effect of sorghum variety on chemical composition and in vitro digestibility of malted grains from Botswana
(Botswana University of Agriculture and Natural Resources, 2013)This study investigated the effects of variety of sorghum on nutritional levels of malted grains. Unscreened grains of BSH1, Mahube, Phofu and Segaolane were malted and analysed for crude protein, minerals, fiber, organic ... -
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, ... -
