Increase of productivity in arugula variety folha-larga under the application of foliar fertilizers / Aumento da produtividade em rúcula variedade folha-larga com aplicação de fertilizantes foliares

Abstract

Organomineral fertilizers are fertilizers of organic origin enriched with mineral nutrients that have been presenting positive responses in several vegetable groves. The aim of this work was to use the experimental factorial design methodology 3 2 and response surface analysis to verify the influences of the variable productivity of the arugula var. Folha Larga. Vegetation® and Spin® foliar fertilizers were applied in factorial design 3 2 , with three repetitions at the central point. The results of this research lead us to affirm that the central point (test 6) with application of 60 mL L -1 of the Vegetation® leaf fertilizers associated with Spin® obtained higher values for the productivity of arugula var. Folha Larga relative to the control.
