Rotavirus and Cryptosporidium infection in bovine calves in Southern Botswana.
(Botswana University of Agriculture and Natural resources, 2012)A cross-sectional study on prevalences of Rotavirus (RV) and Cryptosporidium parvum infections was carried out in dairy and beef calves in 31 farms over a 2-year period. Enzyme immunoassay (EIA) was to determine RV and C. ... -
Ruminant contribution to enteric methane emissions and possible mitigation strategies in the Southern Africa Development Community region
(SpringerLink, 2022-08-31)The Southern Africa Development Community (SADC) region is not a major emitter of greenhouse gases (GHG). However, Sub-Saharan Africa is considered a potential future hotspot for GHG emissions because of its large livestock ... -
Scheduling irrigation from wetting front depth.
(Elsevier, 2016-07-07)Irrigation scheduling is often based around the analogy of a ‘tipping bucket’, and the measurement or prediction of the amount of water stored within the bucket. We compare this conventional approach of scheduling with ... -
Screening soybean (Glycine max L.) Merrill cultivars for response to root-knot nematodes, Meloidogyne (Goeldi) spp. in two agro-ccological zones in Ghana, West Africa
(Botswana University of Agriculture & Natural Resources, 2008)Ten soybean cultivars were grown for two seasons in fields heavily infested by Meloidogyne arenaria, M. incognita and M. javanica in two agroecological zones of Ghana in order to assess their reaction to the root-knot ... -
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 ... -
Seed germination of morama bean (tylosema esculentum (burch) a. schreib) from different collection sites in Botswana
(Botswana University of Agriculture and Natural Resources, 2020-07)Understanding the seed biology and germination ecology of plants is critical for bringing them into cultivation, yet this information is insufficient for Tylosema esculentum despite its potential as a future crop. T. ... -
