BACKGROUND Feeding schemes based on school garden produce have been proposed as an effective solution to food insecurity and hunger among learners in South Africa. However, few studies have looked at the potential contamination of school food gardens when situated near mine tailing dams. OBJECTIVES The aim of the study was to evaluate the potential heavy metal contamination in a school vegeta...
CPS-1 is a subclass B3 metallo-β-lactamase from a Chryseobacterium piscium isolate collected from soil, showing 68% amino acid identity to the GOB-1 enzyme. CPS-1 was overproduced in Escherichia coli Rosetta (DE3), purified by chromatography, and biochemically characterized. This enzyme exhibits a broad-spectrum substrate profile, including penicillins, cephalosporins, and carbapenems, which ov...
In this study, possibility of substituting date palm fibers, as a growth medium, for coco peat was investigated. First, moisture absorption, retention and loosing rate in date palm fibers, coco peat, peat moss, perlite and soil were examined by completely randomized blocks design in two time periods (3 and 5 days), with two groups of materials (date palm fibers- peat moss- perlite and coco peat...
BACKGROUND Faba bean is an important starch-based protein crop produced worldwide. Soil acidity and aluminium toxicity are major abiotic stresses affecting its production, so in regions where soil acidity is a problem, there is a gap between the potential and actual productivity of the crop. Hence, we set out to evaluate acidity and aluminium tolerance in a range of faba bean germplasm using so...
An increase in the emission of greenhouse gases such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) from the soil surface to the atmosphere has been of worldwide concern over the last several decades. Carbon dioxide is recognized as a significant contributor to global warming and climatic change, accounting for 60% of total greenhouse effect. The aim of this research was to dete...
The uptake of arsenic by plants from contaminated soils presents a health hazard that may affect home gardeners neighboring contaminated environments. A controlled greenhouse study was conducted in parallel with a co-created citizen science program (home garden experiment) to characterize the uptake of arsenic by common homegrown vegetables near the Iron King Mine and Humboldt Smelter Superfund...
Chamaecyparis lawsoniana ‘Ellwoodii’, Cryptomeria japonica ‘Elegans’ and x Cupressocyparis leylandii have great importance in terms of usage areas as ornamental plant. The overcoming the problem, that may be encountered generative propagation these taxa, using vegetative method are very important for producers dealing with park garden works. It was investigated effects different greenhouse medi...
A field experiment on the “Effect of seed germination and seedling vigour in different soil media for establishment annual drumstick (Moringa oleifera) cv.PKM-1” was conducted during August to November 2021, naturally ventilated polyhouse Department Horticulture, Naini Agricultural Institute, SHUATS, Prayagraj (U.P.). The Randomized Block Design consisting 12 treatments three replications. cons...
Araucaria excelsa L. of Araucariaceae family is a beautiful conifer which has a high economic importance in the flower industry. A factorial experiment based on randomized completely block design with two factors: 1. Irrigation intervals in 2, 4 and 6 days (I1, I2 and I3) and 2. The growth bed in pots 3 L included M1 (100 % v/v cocopeat), M2 (100% municipal waste compost), M3 (100 % vermicompo...
