Modelling the Control of the Impact of Fall Armyworm (Spodoptera frugiperda) Infestations on Maize Production.
(Hindawi, 2021-03-18)In this paper, we propose and analyse a stage-structured mathematical model for modelling the control of the impact of Fall Armyworm infestations on maize production. Preliminary analysis of the model in the vegetative and ... -
Modeling the Effect of HIV/AIDS Stigma on HIV Infection Dynamics in Kenya.
(Springer Link, 2021-04-05)Stigma toward people living with HIV/AIDS (PLWHA) has impeded the response to the disease across the world. Widespread stigma leads to poor adherence of pre- ventative measures while also causing PLWHA to avoid testing and ... -
Dynamics for a non-autonomous fall armyworm-maize interaction model with a saturation functional response
(AIMS Press, 2021-11-09)In this study, we present a non-autonomous model with a Holling type II functional response, to study the complex dynamics for fall armyworm-maize biomass interacting in a periodic environment. Understanding how seasonal ... -
A fractional-order fall armyworm-maize biomass model with naturally beneficial insects and optimal farming awareness.
(Elsevier, 2021-11-01)Maize remains an important food crop in Africa. However, the production of this crop, and consequently the livelihood of the growers are threatened by the invasion and widespread infestation of the fall armyworm which ... -
Evaluation of variety alone or in combination with diatomaceous earth or pyriproxyfen (an insect growth regulator) for managing plodia Interpunctella (hubner) (lepidoptera; pyralidae) on stored groundnuts (arachis hypogaea L.)
(Botswana University of Agriculture & Natural Resources, 2018-09)In storage, insect pests cause considerable losses to stored groundnut (Arachis hypogaca L.) and one of the major storage pests worldwide is Plodia interpunctella (Hubner). Two experiment were conducted to evaluate the ... -
Evaluation of the diversity and pest status of fruit flies on marula, Sclerocarya Birrea in Gabane, Mochudi and Rasesa
(Botswana University of Agriculture & Natural Resources, 2011-07)Manila (Sclerocarya birrea) is one of the most useful indigenous trees in Africa. The fruits of marula are used to produce useful products such as juice, jam and beer. The seed kernels are very rich in proteins and can be ... -
Quantitative assessment and transfers of potentially toxic metals from soils to vegetable crops in urban and peri-urban agriculture land use system in Botswana.
(Botswana University of Agriculture & Natural Resources, 2015-08)Urban and peri-urban agriculture (UPA) is considered an important source of food for cities and for vulnerable households. It is usually characterized by high input intensity and use of wastewater for irrigation. The ... -
Evaluation of bacillus thuringiensis (var. kurstaki), spinosad and cypermethrin for the control of diamondback moth (plutella xylostella l.) on cabbage.
(Botswana University of Agriculture & Natural Resources, 2011-07)An experiment was conducted al the Botswana College of Agriculture (BCA), Gaborone, Botswana (24° 55’S, 25" 95’E) at an altitude of 998m above sea level to evaluate the effectiveness of Bacillus thuringiensis(Bt), ... -
Phosphate sorption and its relation to soil properties
(Agricultural University of Norway, 1986-12-11)In order to study the phosphorus sorption characteristics of six soils from Botswana, 2g of soil were equilibrated at 20°C in 0.01M CaCl2 containing various amounts of dissolved phosphate (0-900 pg P/g soil for two days). ... -
An assessment of biological nitrogen fixation on legumes growing on farmers’ fields and in natural systems and authentication of associated root nodule bacteria
(Botswana University of Agriculture & Natural Resources, 2017-05)The low inherent soil fertility, especially nitrogen (N) constrains arable agriculture in Botswana. Nitrogen is usually added to soil through inorganic fertilizer application. In this dissertation, biological N? fixation ... -
Land reforms that exclude the poor: the case of Botswana.
(Taylor & Francis Online, 2008-09-03)Land reforms in Botswana, unlike those in other southern African countries, were not undertaken with the primary objective of redistributing land, but rather with the three objectives of increasing agricultural productivity, ... -
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 ... -
The role and potential of tree growing on farms in the Barolong district – Botswana
(University of Aberdeen, 1992)In the Barolong District the depletion of the woodland resource, upon which households are dependent for fuelwood, poles, fencing material, livestock forage and protection of cropland soil, is a cause for concern. The ... -
Effect of leaf bud removal and partial leaf harvesting on growth, development and yield of cowpeas (Vigna unguiculata [L.] Walp.)
(Botswana University of Agriculture & Natural Resources, 2017-05)Cowpea (Vigna unguiculta [L.] Walp.) originates in tropical Africa. Most producers engage in “dual purpose” cowpea production, where sequential harvests of leaves arc made, followed by seed harvest at the end of the ... -

Proximate composition of offal and drumsticks of guinea fowl (Numida meleagris) fed mophane worm and various cereal based diets
(Botswana University of Agriculture & Natural Resources, 2015-08)Two studies were carried out to investigate the effects of feeding mophane worm as a protein source and cereals as energy sources on the chemical composition of offal and drumsticks of guinea fowl (Numida meleagris). ... -
Growth performance, haemo-biochemical parameters, carcass characteristics and meat quality in broiler chickens fed malted sorghum-based diets
(Botswana University of Agriculture & Natural Resources, 2021-06)The study was conducted to investigate the effect of feeding malted sorghum grains in place of maize grains on growth performance, blood parameters and meat quality of Ross 308 broiler chickens (R3O8BC). A pilot work (Study ...
