Maceration Time Affects the Efficacy of Borage Extracts as Potential Biostimulant on Rocket Salad

The efficacy of plant-based biostimulants lays on the extraction of bioactive compounds that can trigger positive biological responses in plants. Their use has been increasing for lowering the production costs, enhance the yield and the stress tolerance, and improve the cropping systems’ sustainabil...
