Evaluation of three breeding cycles for seedling weight of switchgrass, big bluestem, and indiangrass.
(Crop Science Society of America, 2014-07-01)
A modified form of restricted, recurrent phenotypic selection was used to select for seedling shoot weight in switchgrass (Panicum virgatum L.), big bluestem (Andropogon gerardii Vitman), and indiangrass [Sorghastrum nutans ...
Preliminary investigation of transfer of metals from soil to vegetables: Case study of Spinacia oleracea L.
(Academic Journals, 2016-09)
The objective of the study was to measure concentrations of Cu, Ni and Zn in Spinacia oleracea cultivated at a site near the copper and nickel mine in Selebi Phikwe. The mean concentrations (in dry matter-basis) of Cu, Zn ...
Ethnozoological Survey of the Indigenous Knowledge on the Use of Pangolins (Manis Sps) in Traditional Medicine in Lentsweletau Extended Area in Botswana.
(Researchgate, 2014-06-30)
Animals have played an important role in human life from prehistory. Many animals are used in zootherapy worldwide. However, the zootherapeutic practices by some communities are not well documented and may be forgotten. ...
A novel pentacyclic triterpene glycoside from a resin of Commiphora glandulosa from Botswana
(African Journal of Pharmacy and Pharmacology, 2010)
A novel ursane-type pentacyclic triterpene glycoside, 1β,2β,3β-trihydoxy-urs-12-ene-23-oic-rhamnoside was isolated from the resin of Commiphora glandulosa Schinz by bioassay guided fractionation. Crude aqueous and chloroform ...
Seed dispersal by serrated tortoises (Psammobates Oculiferus) and the effect of their gut passage on seed germination.
(Researchgate, 2014-10-27)
Some tortoises are frugivores and can disperse seeds away from the parent plant to areas favourable for their establishments through gut passage. We investigated the plant species dispersed by the serrated tortoise ...
Deposition rates of atmospheric particulates determined from 210Pb measurements in soils and air
(HARD Publishing, 2010)
Deposition rates of atmospheric particles were determined using previously published
210Pb data in soils and air. The dry deposition velocities for moorland and woodland soils
were 2.2±1.8 and 9±2 mm• s-1, respectively. ...
The effect of purified condensed tannins of forage plants from Botswana on the free-living stages of gastrointestinal nematode parasites of livestock.
(Elsevier, 2013-10-18)
The effect of condensed tannins (CT) extracted from forage plants from Botswana on the free-living stages of a number of species of gastrointestinal nematode parasites derived from infected sheep were investigated using ...
A mathematical model for fall armyworm management on maize biomass
(SpringerLink, 2012)
Fall armyworm (Spodoptera frugiperda), a highly destructive and fast spreading agricultural pest native to North and South America, poses a real threat to global food security. In this paper, to explore the dynamics and ...
Drought and grazing influence on Northern Chihuahuan desert rangelands, New Mexico.
(Botswana University of Agriculture and Natural resources, 2013)
A short term cattle grazing trial was started in June 1992 in the Chihuahuan Desert in Southern New Mexico to study the influence of drought and grazing on plant responses. Paddocks were grazed in June and September each ...
Gross and microanatomical changes at the weight bearing points of ostrich induced by soil or concrete floor and implications for welfare.
(Botswana University of Agriculture and Natural resources, 2013)
This study investigated the gross and microanatomical changes occurring at the weight bearing points on the ostrich body surface induced by rearing on soil floor or on concrete floor and the implications for the welfare ...
