Qualidade e teor de nutrientes em sementes de couve manteiga oriundas de sistemas convencional e orgânico

Abstract

Horticulture is an activity of great relevance in economic and social aspects and in view of the environmental issues in evidence, it is necessary to seek alternatives to the conventional model of agricultural production, thus organic agriculture can be viewed as one of the tools available for a agricultural production that seeks sustainable development. Considering that kale stands out in the vegetable market and the need for information on the quality of organic seeds available, the present work aimed to verify the quality and nutrient content of certified organic and conventional kale seeds through the evaluation of germination, vigor, electrical conductivity and nutrient content. The results of the analyzes did not show a significant difference in the quality of the seeds between the systems, since both organic and conventional seeds presented more and less expressive results. The analysis of seed micronutrients demonstrated a significant correlation between germination, IVG, VG, electrical conductivity and the nutrient zinc.
