Crop systems were: organic system in soil with (ORG) or without straw (ORGWS), conventional system in rockwool with a high nutritive solution concentration (CONV-RWH), conventional system in rockwool with a low nutritive solution concentration (CONV-RWL), and conventional system in soil (CONV-S). The interaction between Cultivars and Crop systems was not significant and therefore, only the main effects were considered. For each parameter (cultivar and crop system), within each column, values followed by a similar letter are not significantly different according to Tukey test (P ≤ 0.05).
