Biostimulants are substances and/or microorganisms that applied to plants or the rhizosphere in order enhance natural process improving absorption of nutrients and quality crops as well tolerance abiotic stresses. A new biostimulant was developed from sewage sludge through its fermentation with Bacillus licheniformis a plant growth-promoting bacteria (PGPB). The fermented product includes three...

Baltic seaweeds were used to obtain aqueous extracts (E) through changing initial pH of deionised water added to algal biomass (EpH3·H2O, EpH7·H2O, and EpH10·H2O) and through changing pH of the mixture of algae and deionised water (EpH3, EpH7, and EpH10). Algal extracts were characterized in terms of the concentration of polyphenols and micro- and macroelements. The highest concentration of pol...

A simple and reliable high-performance liquid chromatographic method that uses photodiode array detection was developed for the simultaneous determination of 12 native and synthetic plant hormones, i.e., plant growth regulators (PGRs), in fertilizers, such as 1-naphthol, 2,4-dichlorophenoxyacetic acid, 4-(2,4-dichlorophenoxy)butyric acid, 4-chlorophenoxyacetic acid, indole-3-acetic acid, 4-(3-i...

Phosphorus (P) is a critical nutrient used to maximize plant growth and yield. Current agriculture management practices commonly experience low plant P use efficiency due to natural chemical sorption and transformations when P fertilizer is applied to soils. A perplexing challenge facing agriculture production is finding sustainable solutions to deliver P more efficiently to plants. Using presc...

The efficacy of plant-based biostimulants lays on the extraction bioactive compounds that can trigger positive biological responses in plants. Their use has been increasing for lowering production costs, enhance yield and stress tolerance, improve cropping systems’ sustainability. aim this work was to investigate effect maceration time borage extracts, subsequently sprayed rocket plants hydropo...
