Abstract

Cauliflower has an important role for human health because it contains vitamins and minerals that are needed by the body. These vegetables can help the digestion process, neutralize acidic substances and facilitate defecation The purpose of this study was to determine the interaction of mulch types and concentrations of fertilizer leaves of Plantafol (5:15:45) on the growth and production of white broccoli plants (Brasssica olleracea var. Botrytis L.) Kusuma F1 varieties. The research was conducted in Tondomulyo Hamlet, Gadungan Village, Puncu Subdistrict, Kediri Regency with a altitude of 250 meters above sea level, with a tropical climate with an average temperature of 27ºC.
