Comparative effects of Bioslurry and chemical fertilizer on soil properties and performance of Spider plant (Cleome gynandra L).
(Buan, 2024-09)Spider plant (Cleome gynandra L.) is a promising indigenous leafy vegetable in the diet of many African rural populations. However, soil fertility for production of spider plant remains an unexploited area leading to low ... -
Comparative growth performance and semen characteristics of indigenous naked neck tswana and black australorp x naked neck tswana chickens under an intensive management system in Botswana.
(Botswana University of Agriculture and Natural Resources, 2020-10)This study investigated growth performance and semen characteristics of naked neck Tswana and black Australorp X naked neck Tswana chickens. The birds were raised under intensive management system from day old to 20 weeks ... -
A comparative study of growth performance and sensory evaluation of Tswana and Orpington chickens reared up to 18 weeks of age under intensive system
(Botswana University of Agriculture & Natural Resources, 2017-06)Two studies were carried out to compare growth performance, carcass characteristics and sensory evaluation of local Tswana chickens and Orpingtons. In the first study, a total of 120 day-old chicks (60 Tswana and 60 ... -
Comparison of genetic and immunological responses to tick infestation between three breeds of sheep in South Africa
(University of the Free State, 2016-01)The study investigated genetic parameters and immunological responses to tick infestation in three South African sheep breeds (Namaqua Afrikaner [NA], Dorper and SA Mutton Merino [SAMM]). The study aimed to estimate genetic ... -
Current state and updating of heat and moisture production of poultry and their housing systems
(Iowa State University, 2002)An extensive literature review and comparative analysis of heat and moisture production (HP, MP) of various poultry types (layers, broilers, and turkeys) and their housing systems indicated that total heat production (THP, ... -
Design and development of a borehole pumping and water level monitoring control system in Botswana
(Botswana University of Agriculture & Natural Resources, 2017-11-07)Botswana experiences recurrent droughts and has limited surface water resources with the average annual rainfall varying from a minimum of less than 250 mm in the Southwest region and a maximum of about 650 mm in the ... -
The design and use of agroforestry systems in Botswana
(University of Edinburgh, 1996)Botswana is a semi-arid country which has 80% of the population living in rural areas and engaged mainly in agriculture. Rural populations in Botswana depend heavily on woodlands for fuelwood, fencing poles, building and ... -
