Uso do produto Siapton® na produção de tomate em hidroponia.

Tomato (Lycopersicon esculentum) is one of the most important vegetable species in the world, being used for fresh consumption and for industry. In Brazil, tomato is one of the most commercially important fruit vegetables and, currently, there is a growing demand for tomatoes produced without the use of harmful pesticides, with quality and affordable prices. Thus, it is necessary to seek ways of cultivation that meet the demands of consumers. In this context, there is great interest in studying the efficiency of the use of Siapton biostimulant in tomato plants. This is a product manufactured and distributed by the Italian company ISAGRO, which promises to improve plant efficiency with greater start-up and vegetative development. This study aims to evaluate the influence of different dosages of the biostimulant Siapton on the performance of tomato plants under hydroponics. The experiment was carried out in the Olericulture Sector of the Federal Institute of Education, Science and Technology of Minas Gerais-Campus Bambuí. Tomato seedlings of the Santa Clara type were used, with four treatments and four replications. The four treatments used different dosages of the commercial product SIAPTON 10 L (0,0 ml L־¹; 1,5 ml L־¹; 3,0 ml L־¹ e 4,5 ml L־¹). The product was applied together with water via foliar and the applications were carried out on the seedlings, before being transplanted, and on the plants, 17 days after transplanting to the hydroponic system. The characteristics analyzed were: total and average weight of fruits per plant, longitudinal diameter, transversal diameter and number of fruits per plant. The different dosages of Siapton product evaluated did not promote statistical differences for any of the characteristics analyzed in the production of tomato cultivar Santa Clara under hydroponics system.
