Identification of the causal agent of sorghum leaf blight and evaluation of its current management practices in Pandamatenga farming area
(Botswana University of Agriculture & Natural Resources, 2015-08)
Turcicum Leaf Blight (TLB) of sorghum incited by Exserohilum turcicum is a major threat to sorghum production globally. This pathogen has been reported to attack both maize and sorghum resulting in yield losses as high as ...
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 ...
Biology and Ecology of Glyphosate-Resistant Giant Ragweed
(Purdue University, 2013)
Giant ragweed (Ambrosia trifida L.) is a competitive annual plant found in disturbed landscapes and is the most troublesome weed in Indiana and the US Corn Belt. It is one of the most common and problematic weeds in corn ...
Quantitative assessment and transfers of potentially toxic metals from soils to vegetable crops in urban and peri-urban agriculture land use system in Botswana.
(Botswana University of Agriculture & Natural Resources, 2015-08)
Urban and peri-urban agriculture (UPA) is considered an important source of food for cities and for vulnerable households. It is usually characterized by high input intensity and use of wastewater for irrigation. The ...
Mineral intake and utilisation by guinea fowl (Numida meleagris) fed different local protein and energy sources
(Botswana University of Agriculture & Natural Resources, 2013-08)
Two studies were carried out to investigate the effects of feeding different locally available protein and energy sources on mineral utilisation by guinea fowl were investigated. In the first study, ninety-six-day old keets ...
Effects of storage temperature and hot water treatment duration on chilling injury and quality of mango (Mangifera indica L.)
(Botswana University of Agriculture & Natural Resources, 2016-08)
Low temperature storage is the most effective method of extending postharvest life and marketing period, and maintain fruit quality because it retards physiological processes such as respiration, ethylene production, ...
Performance of dairy goats in selected regions of Botswana and the effect of improved management practices on milk yield and composition
(Botswana University of Agriculture & Natural Resources, 2015-11)
In Botswana milk production generally come from dairy cattle breeds, but there are some goat breeds that have the genetic potential for producing large quantities of milk. This dissertation was a record of two studies on ...
Effect of soil water deficit on water use efficiency of cowpea (Vigna unguiculata L. Walp)
(Botswana University of Agriculture & Natural Resources, 2016-09)
There is a global concern over the capacity to feed a rapidly growing world population against a background of climate change which challenges productivity of major crops such as cowpea and their ability to ensure food ...
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 ...
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 ...
