Biostimulanteffect of algae (Arthrospira platensis and Durvillaea antarctica) on the development of cornplantsduringthe V3 vegetativestage

Abstract

The objective was to evaluate the biostimulants effect of algae Arthrospira platensis and Durvillaea antarctica on the development of corn during the V3 vegetative stage and a control treatment. For this, seeds of hybrid corn DK-7088 were used, sown in a pot with a capacity of 2 kg of soil, one seed per experimental unit and 10 replicates were considered. The application frequencies of the treatments were carried out on days (0, 4, 8 and 12). Fifteen days after emergence, plant height, number of leaves, leaf length, leaf width, stem diameter, root length, fresh biomass, dry biomass and dry matter were evaluated. It was concluded that the application of algae-based biostimulants, especially Arthrospira platensis at a dose of 10 mL/plant, significantly improved the growth of DK-7088 hybrid corn plants up to the V3 vegetative stage.
