Physiological Response of Pea (Pisum sativum L.) Plants to Foliar Application of Biostimulants

The use of biostimulants in crop production can be an economically viable option for farmers and enable them to meet the increasing quality standards agricultural products consumer expectations sustainability environmental protection. aim this study was determine effect foliar application on course physiological processes pea (Pisum sativum L.) plants. Field studies with conventional fertilizers/biostimulants plant origin (N1) ecological biostimulant animal (N2) cultivation eight varieties were carried out years 2015–2017 south-eastern Poland. With favorable weather conditions during flowering pod setting period, as a result N1 N2 fertilization, BBCH 65 79 phases, there significant increase relative Chl content, fluorescence parameters (Fv/Fm, Fv/F0, PI) gas exchange (Pn, E, gs), measured bracts. content more favorably affected by fertilization. Our data also confirm beneficial application, but weaker than N1, which determined strong negative reaction plants fertilization 2016, rainfall shortages development phases. experiment showed that applied preparations have positive occurring plant, drought they do not significantly mitigate its effects.
