Effects of nitrogen and phosphorus on growth, development, yield, and oil content of safflower (Carthamus tinctorius L.)
(Botswana University of Agriculture & Natural Resources, 2017-07)
Safflower is a multipurpose crop grown for the orange-red dye that is obtained from its petals, medicinal properties, feed value and especially for its high quality oil (Dajue and Mondel. 1996; Dwivedi, 2005; Sirel and ...
Evaluation of the nutritional potential of safflower (Carthamus tinctoriiis L.) leaves, seed and cake after oil extraction to be used as animal feed
(Botswana University of Agriculture & Natural Resources, 2017-09)
Safflower is an annual oil seed crop adapted to arid and saline regions of the world, is a
potentially novel food and medicine source, which has not been fully explored in the last
century. Safflower’s ability to forage ...
Effect of nitrogen fertilizer and planting density on the growth and yield of intercropped sorghum and cowpea under rainfed conditions
(Botswana University of Agriculture & Natural Resources, 2017-11)
Cereal-legume intercropping can be an alternative for smallholder farmers to mitigate the effects of climate change and to promote sustainable agricultural production. A field experiment was conducted at BUAN gardens during ...
Characterisation of Jatropha curcas L. germplasm within Botswana using morphological and molecular markers (SSR)
(Botswana University of Agriculture & Natural Resources, 2017-06)
Jatropha curcas L. is an undomesticated plant species that has recently received great attention
for its utilization in biofuel production in many countries including Botswana. The main goal of
this study was to identify ...
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 ...
Vegetation and soil conditions around water points in ranching and communal grazing systems in the hard veld and sandveld of Botswana
(Botswana University of Agriculture & Natural Resources, 2017-05)
Artificial water sources or boreholes were introduced in Botswana to mitigate surface water scarcity in rangelands and aid livestock production. Gradually piospheres were observed, areas close to water points experienced ...
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 ...
An assessment of biological nitrogen fixation on legumes growing on farmers’ fields and in natural systems and authentication of associated root nodule bacteria
(Botswana University of Agriculture & Natural Resources, 2017-05)
The low inherent soil fertility, especially nitrogen (N) constrains arable agriculture in Botswana. Nitrogen is usually added to soil through inorganic fertilizer application. In this dissertation, biological N? fixation ...
Influence of sorghum-legume intercrop on insect diversity, natural enemies and damage on sorghum by spotted stemborer (chilo partellus swinhoe) (lepidoptera:crambidae)
(Botswana University of Agriculture & Natural Resources, 2017-06)
Stemborers are considered major pests of sorghum (Sorghum bicolor (L) Moench) in Botswana. An evaluation of the effect of intercropping sorghum with legumes on insect diversity, natural enemies and damage on sorghum by ...
Effect of leaf bud removal and partial leaf harvesting on growth, development and yield of cowpeas (Vigna unguiculata [L.] Walp.)
(Botswana University of Agriculture & Natural Resources, 2017-05)
Cowpea (Vigna unguiculta [L.] Walp.) originates in tropical Africa. Most producers engage in
“dual purpose” cowpea production, where sequential harvests of leaves arc made, followed by
seed harvest at the end of the ...
