SOURCES AND CONCENTRATIONS OF BIOFERTILIZERS FOR THE ORGANIC PRODUCTION OF ARUCULA AND RADISH

Abstract

For organic food production, it is necessary to use efficient, economical inputs that do not cause or have
minimal impacts on health and the environment. In this context, the use of biofertilizers can become an
essential tool. The objective of this work was to evaluate the production of arugula and radish under organic
cultivation, with the application of different sources and concentrations of liquid biofertilizers. The
experimental design used was randomized blocks, in a 2 x 5 factorial arrangement, with 2 biofertilizer
formulations (B1-Agrobio and B2-Vairo) and five concentrations (0, 2%, 4%, 8%, and 16% v/v). As treatments
sprayed weekly, with four replicates. The following characteristics were evaluated for arugula culture: number
of leaves, leaf area, plant height, weight of fresh and dry plant biomass of the area, and productivity. For the
radish, the diameter, length, fresh weight, and productivity of roots were evaluated. Variables whose “F test”
was significant (p ≤ 0.05) were submitted to linear regression analysis. Arugula and radish yields were
influenced by different sources and dosages of biofertilizers. For arugula, the highest productivity (15.29 t ha1) was obtained at the dose of 8.5%, with the use of Vairo Biofertilization. For radish, there were no differences between the sources, in which the maximum productivity (19.9 t ha-1) was obtained when doses of 8.0% of both biofertilizers were used.
