Abstract

Agronomic parameters were assessed in broccoli ( Brassica oleraceae L. var. italica), cv. Legacy, in different cultivation systems: Natural 1 [incorporation of elephant grass Pennisetum purpureum Schumacher cv. “Napier” (50 ton/ha), Bokashi compost (1,5 ton/ ha) and EM-4 spraying (20 l/ha)]; Natural 2 [Bokashi compost (1,5 ton/ ha) and EM-4 spraying (20 l/ha)]; Conventional (NPK in the planting + bórax + dressing N)]; Organic [organic compost (1 kg/plant)]. Plants high were assessed 30, 45 and 60 days after planting; cycle; fresh weight; shelf life and dried weight were also evaluated. Fresh weight of leaves and stems in conventional was higher then in organic treatment. Inflorescence fresh weight, leaves and stems dried weight and shelf life were similar among treatments. The inflorescence fresh and dried weight from conventional were higher than those from Organic and Natural 1. Cycle found in Natural 1 was longer than the other treatments.
