(Elservier, 2013)The making of butter from camel milk using a traditional churning method and the physicochemical properties of the butter were assessed. Camel milk was obtained from pastorally managed camels in the Erer valley, eastern ... -
Phosphorus levels in shoots of Bambara groundnut in Botswana soils
(Taylor & Francis, 2002)The critical phosphorus (P) concentration and range of bambara groundnut (Vigna subterranea) plants were determined from a sand culture experiment at Botswana College of Agriculture. Twelve P levels (0.207–159 mg P pot−1) ... -
Potassium→ammonium exchange of two benchmark soils from Botswana and its implication for nitrogen economy of the soils
(Taylor & Francis, 2014)Ion exchange preferences for NH4+ and K+ by soil exchanger surface can greatly affect the NO3− leaching into groundwater and nitrogen-use efficiency in agricultural production. Since NH4+ and K+ salts are usually applied ... -

Influence of flooding on bambara groundnut (Vigna subterranea L.) germination: Effect of temperature, duration and timing
(Academic Journals, 2009)To evaluate the response of bambara groundnut seeds to flooding stress a laboratory study (experiment 1) and a greenhouse study (experiment 2) were conducted. In the laboratory study seeds of a brown-coloured local bambara ... -
Growth rate of ostrich (struthio camelus) chicks under intensive management in Botswana
(Springer, 1998)Thirty-seven ostrich chicks raised artificially had their weights, lengths of metatarsus and heights measured weekly from hatching to the 16th week. Despite weight loss during the first week due to utilization of egg yolk ... -
