QUALIDADE FISIOLÓGICA DE SEMENTES DE SOJA SOB TRATAMENTO COM BIOESTIMULANTE

Abstract

The production of high-quality soybean seeds is a challenge for the seed sector, especially in tropical and subtropical regions. The seeds physiological quality may also be associated with their chemical treatment. The objective of this work was to evaluate the physiological performance of soybean cultivars seeds under treatment with Penergetic Planta. The work was carried out at the Laboratório de Sementes do IF Goiano, Campus Rio Verde, using soybean seeds from the cultivars BRS 6970 IPRO, Nidera 7007 IPRO and Monsoy 7110 IPRO, from the 2016/2017 crop of the same seed producer. The seeds were treated with three doses of Penergetic Planta, 1, 2 and 3 g / 100 Kg of seeds, besides a treatment without the addition of Penergetic Planta. The experiment was set up in a completely randomized design in a 3 x 4 factorial scheme (cultivar x dosage of Penergetic Plant), with 4 replications of 50 seeds. At 4 months of storage, germination at first and second count, germination speed index, abnormal seedlings percentage and shoot and root system growth were evaluated. The application of Penergetic Planta up to 2 g / 100 Kg-1 dose, increases germination speed, emergence speed, root system growth and shoot. Seeds of NS 7007 IPRO and M 7110 IPRO soybean cultivars show increased physiological performance with increasing Penergetic Plant dosage in seed treatment.
