Yellow plums (Prunus domestica L) conventionally and organically grown in the same farm were selected to study the influence of different agronomic practices on antioxidant vitamins (ascorbic acid, vitamin E, beta-carotene) and phenolics (total polyphenols, phenolic acids, flavonols) concentration. Conventional plums were grown on tilled soil. Three organic cultivations were performed: tilled s...

Yttrium doping-stabilized γ-Fe2O3 nanoparticles were studied for its potential to serve as a plant fertilizer and, through enzymatic activity, support drought stress management. Levels of both hydrogen peroxide and lipid peroxidation, after drought, were reduced when γ-Fe2O3 nanoparticles were delivered by irrigation in a nutrient solution to Brassica napus plants grown in soil. Hydrogen peroxi...

INTRODUCTION The primary limitations of conventional weed control programs include a heavy reliance on capital intensive, toxic, and non-renewable resources (pesticides and petrochemicals) to manage weed competition. Weed emergence from the soil top layers is facilitated by the continuous disturbance created through cultivation, irrigation, pesticide applications, machinery, and other cultural ...
