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 ... -
