Effect of bacterial inoculation of strains of pseudomonas aeruginosa, alcaligenes feacalis and bacillus subtilis on germination, growth and heavy metal (cd, cr, and ni) uptake of brassica juncea
(Taylor & Francis, 2016)Bacterial inoculation may influence Brassica juncea growth and heavy metal (Ni, Cr, and Cd) accumulation. Three metal tolerant bacterial isolates (BCr3, BCd33, and BNi11) recovered from mine tailings, identified as Pseudomonas ... -
Effect of biofumigants on soil microbial communities and ecotoxicology of earthworms (Eisenia andrei)
(Springer, 2016)Biofumigation is considered a good alternative to chemical fumigation because it can control crop pathogens and diseases with lower health and environmental risks than chemical fumigants. Glucosinolates are volatile compounds ... -
Effect of biomass feedstock composition on biochar properties produced through hydrothermal liquefaction
(EARET, 2018)The effect that 6 different biomass feedstocks have on biochar was investigated. The biochar was produced through hydrothermal liquefaction at temperatures of 260˚C and 300˚C. The effect of temperature was also investigated. ... -

(IBIMA, 2012)Changes in organisations due to various factors such as technological advancements or competition may bring the effect of change to certain business processes. This in turn invokes business process re-engineering (BPR) and ... -
The effect of Busseola fusca infestation, fungal inoculation and mechanical wounding on Fusarium ear rot development and fumonisin production in maize
(Elsevier, 2017)Fusarium verticillioides and Busseola fusca are among the most significant biotic constraints to maize production in South Africa. In this study, the effect of B. fusca damage and mechanical wounding to maize ears on ... -
The effect of canola (Brassica napus) as a biofumigant on soil microbial communities and plant vitality: a pot study
(Taylor & Francis and NISC, 2013)Canola (Brassica napus) may be incorporated into soil as a biofumigant for control of pathogens such as Sclerotinia sclerotiorum. Yet, the effect of biofumigants on natural microbial communities required to maintain soil ... -
The effect of carbon dioxide partial pressure on the gasification rate and pore development of Highveld coal chars at elevated pressures
(Elsevier, 2018)Char structural changes occurring during gasification are normally only related to conversion and few data is published on the effect of carbon dioxide partial pressure on the extent of pore development. In this study, the ... -
The effect of carbonaceous reductant selection on chromite pre-reduction
(Springer, 2017)Ferrochrome (FeCr) production is an energy-intensive process. Currently, the pelletized chromite pre-reduction process, also referred to as solid-state reduction of chromite, is most likely the FeCr production process ... -
The effect of casino employees demographic variables on quality of work-life domains
