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, ... -
Economics of Smallholder Sorghum and Maize Production Systems in Botswana: a Comparative Analysis
(Journal of Agriculture in the Tropics and Subtropics, 1997-10)Sorghum and maize, the predominant crops of smallholder farmers in Botswana, compete for the same limited resources of the farmers. Unfortunately very little is known about their relative economic efficiency. Using farm-level ... -

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 ... -
Correlated responses in tissue weights measured in vivo by computer tomography in Dorset Down sheep selected for lean tissue growth
(Bureau for Scientific Publications, 2003)The aim of this study was to estimate correlated responses in lean, fat and bone weights in vivo in Dorset Down sheep selected for lean tissue growth. Over the period 1986-1992 inclusive, the lean tissue growth line had ... -
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 ... -
Drought responsive genes and their functional terms identified by GS FLX Pyro sequencing in maize
(Forestry Reaserch Centre, 2014)Drought stress is a major challenge for the production of maize (Zea mays L), leading to reduced growth of aerial parts and, to a large extent, reproductive stages of development. We applied the 454 GS FLX titanium platform ... -
