NITROGEN FERTILIZATION IN THE DEVELOPMENT OF Brassica oleracea L.

Leaf kale is a crop that widely consumed today due to the new ways of using it in cooking and its nutritional properties. However, has high requirement for nitrogen fertilization, so excessive application mineral fertilizers causes environmental impacts. Considering importance requirement, objective this work was evaluate effect organomineral fertilization on development cv. Butter. The treatments were distributed randomized blocks, 2x4 factorial scheme, referring two sources (urea cattle manure) four doses (0, 50, 100 150% dose 120 kg ha-1 ) with three replications during growing seasons. used urea bovine manure. Plant height, number leaves, leaf area, stem diameter, fresh dry mass shoots analyzed. positively influenced aerial part. Cultivation season 1 favored increase evaluated variables lower percentage used. Greater leaves achieved by (higher dose) 2.
