The production innovations have been evolving more and more towards organic, sustainable or environmental friendly systems. Contemporarily, the yield and the quality of crops must be assured. The reduction of fertilisers may be obtained by improving the nutrients uptake or their utilisation by the plants. The aim of our work was to verify if the progressive reduction of nutrient solution concen...

A plant biostimulant is any substance or microorganism applied to plants with the aim to enhance nutrition efficiency, abiotic stress tolerance and/or crop quality traits, regardless of its nutrients content. By extension, plant biostimulants also designate commercial products containing mixtures of such substances and/or microorganisms. The definition proposed by this article is supported by a...

An alfalfa-based protein hydrolysate (EM) has been tested in tomato (Solanum lycopersicon L.) plants at two different concentrations (0.1 and 1 mL L-1) to get insight on its efficacy as biostimulant in this species and to unravel possible metabolic targets and molecular mechanisms that may shed light on its mode of action. EM was efficient in promoting the fresh biomass and content in chlorophy...

Most agricultural practices have evolved towards biological and sustainable systems. The purpose of modern agriculture is to reduce inputs without reducing yield quality. This objective can be achieved through the identification organic molecules capable activating plant metabolism. Biostimulants contain a wide range mostly still unknown bioactive compounds. These products are generally able im...

The excessive use of chemical fertilizers can lead to severe environmental damages. In recent decades, the application biostimulants improve soil composition and stimulate plant growth has contributed significantly preservation. this paper, we studied effect a rhizogenic biostimulant, obtained from fulvic acids, probiotics, prebiotics, on fertility two types soils, sandy loam in which turfgrass...

Promising strategies that could aid a shift from N-intensive agriculture to an eco-friendlier approach include the integrated use of plant-based biostimulants. To date, results about accumulation nitrate in green leafy vegetables due biostimulant application are conflicting. Therefore, current study aimed at assessing effect new biostimulant, containing triacontanol (TRIA), is claimed reduce le...

The availability of orthophosphate (Pi) is a key determinant of crop productivity because its accessibility to plants is poor due to its conversion to unavailable forms. Weed's competition for this essential macronutrient further reduces its bio-availability. To compensate for the low Pi use efficiency and address the weed hazard, excess Pi fertilizers and herbicides are routinely applied, resu...

Unexpected reactor accidents and radioisotope production and consumption have led to a continuous increase in the global-scale contamination of radionuclides. In particular, anthropogenic radioiodine has become critical due to its highly volatile mobilization and recycling in global environments, resulting in widespread, negative impact on nature. We report a novel biostimulant method to effect...
