Effect of control plot density, control plot arrangement, and assumption of random or fixed effects on nonreplicated experiments for germplasm screening using spatial models
(Crop Science Society of America, 2005)Early generation selection experiments typically involve several hundred to thousands of lines. Various systematic and statistical techniques have been developed to increase effectiveness and efficiencies in such experiments, ... -
Documentation of indigenous knowledge and best-bet practices on the use of animals and plants for sustainable natural resources management in Botswana
(Botswana University of Agriculture and Natural Resources, 2014)A study was carried out to document indigenous knowledge (IK) and practice on use of animals and plants, and best-bet practices (BBPs) during Phase I (2003-2004) of the Desert Margins Programme (DMP), whose overall objective ... -
Determination and source apportionment of selected heavy metals in aerosol samples collected from Sebele
(Science Publication, 2013-05-17)Bush fires and dust in the dry winter months establish moderately high background levels of aerosols. Emissions into the atmosphere by copper mines, coal mines and vehicular emissions are all possible sources of air pollution ... -
Cooling laying hens by intermittent partial surface sprinkling
(American Society of Agricultural and Biological Engineers, 2000)This study investigated the efficacy of intermittent partial surface sprinkling to cool caged layers at 20, 38, and 56 weeks of age. Ten birds were used per age group with two birds per paired trial (Experiment, Expt, and ... -
Calcium-Ammonium Selectivity of Two Benchmark Soils from Botswana as Assessed by Competing Semi-empirical Ion Exchange Equations
(Taylor & Francis, 2015)The effectiveness of lime-ammonium-nitrate (LAN) as a nitrogen (N) fertilizer in weathered soils depends on the respective selectivity for ammonium (NH4) and calcium (Ca) by the soils. The study assessed Ca2+/NH4+ exchange ... -
Control of Cowpea Weevil, Callosobruchus Maculatus (F.) (Coleoptera: Bruchidae), Using Natural Plant Products
(MDPI, 2014-12-31)A laboratory study was conducted to investigate the effects of natural products on the reproduction and damage of Callosobruchus maculatus, the cowpea weevil, on cowpea seeds at Botswana College of Agriculture in Gaborone, ... -
African Yam Bean: An Under-Utilized Legume with Potential as a Tuber and Pulse Crop
(Taylor & Francis, 2007)AfricanYamBean (Sphenostylisstenocarpa)isalegume that provides nutritionally rich seeds, tubers and leaves for human consumption. Production relies upon the cultivation of landraces and, to some extent, the collection of ... -
Contribution of red alder to soil nitrogen input in a silvopastoral system
(Springer-Verlag, 2007-01-11)Studies on Alnus rubra Bong. (red alder) were carried out to assess its potential for use as a component of a silvopastoral system. Comparison was between two treatments: red alder at 400 stems ha−1 (silvopasture) and red ...
