(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 ... -
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 ... -
Evaluating different soil tillage surface conditions on their rainwater harvesting potential in Botswana
(African Journal of Rural Development (AFJRD), 2015-10-03)Rain water harvesting (RWH) is described as concentration, collection, storage and use of rain fall via runoff for various purposes such as domestic, livestock and agricultural use. RWH systems can be classified as macro, ... -
Evaluating the Growth Response of Cassia abbreviata oliv. Seedlings to Growing Mediain Botswana
(International Science Community Association, 2013-11)A pot experiment was conducted at the Botswana College of Agriculture nursery to investigate effects of growing media on the growth of Cassia abbreviata. A completely randomized design (CRD) with four treatments: top garden ... -
Evaluation 16 elite sugarcane lines for ethanol yield and yield related traits under rainfed conditions.
(Southern Cross Publishing, 2021-07-01)The world demand for clean renewable energy has seen a rise in use of sugarcane in production of bioenergy products like bioethanol which is produced from molasses and extracted juice of stalk. This then brings a competition ... -
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 ... -
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 ... -
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 ... -
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, ... -
Feeding Values and Anti - Nutritive Factors of Forage Tree Legumes
(Asian Network for Scientific Information, 2003)Animal production in Botswana suffers from inadequate feed quantities and qualities, due mainly to semi-arid low rainfall which can barely support arable farming in most years. This problem is compounded by the competition ... -
Fish handling and postharvest losses around the Fincha’a, Amarti, and Nashe reservoirs in Oromiya, Ethiopia.

Genotypic variation in response to drought stress is associated with biochemical and transcriptional regulation of ureides metabolism in common bean (Phaseolus vulgaris L.).
(University of Ljubljana, 2022-05-29)Ureidic legumes such as common bean (Phaseoulus valgaris L.) plants export nitrogen from the nodules to shoots and leaves as ureides during symbiotic biological nitrogen fixation. Common bean gene encoding allantoinase ... -
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 ... -
Growth chamber and field evaluation of physiological factors of two watermelon genotypes.
(Elsevier B.V, 2021-05-28)Drought is a major threat to food security worldwide, and drought-tolerant plants are a convenient model to study the mechanisms underlying drought tolerance. Some of the studies on drought tolerance mechanisms have been ... -
Heat and moisture production and minimum ventilation requirements of tom turkeys during brooding-growing period.
(American Society of Agricultural Engineers, 1998)Heat and moisture production rates of Nicholas tom turkeys raised under lab-scale commercial production settings were continually measured during a five-week brooding-growing period. Functions were established that relate ... -
High Aluminium Concentration and Soil Acid Saturation Reduce Germination, Emergence and Seedling Establishment of Groundnut.
(African Journals Online, 2020-02-22)Studies on crop responses to soil acidity have largely neglected the germination and seedling establishment stages. The objective of this study was to determine the effect of soil acidity, including aluminium per se and ... -
