Abstract

Floating hydroponic system is simple hydroponic system, because roots can absorb nutrient element the sub merged direct root nutrients solution. The ratio of macro-micro fertilizer to hydroponic can effect leaf growth. The aimed of this research was to know effect of ratio macro-micro fertilizer on Brassica oleracea leaf. The research was conducted at Jatinangor subdistrict from August to October 2018 used Randomized Complete Design with nine replications. The study was conducted to examine various macro (NPK, CaSO4, MgSO4, K2SO4 and Soluble Micro Mix fertilizer ratio i.e : A (AB Mix) as a control, B (1250 : 312.1 : 583.68 : 250 : 50), C (1250 : 312.1 : 583.68 : 250 : 70), D (1250 : 312.1 : 583.68 : 250 : 90), E (1250 : 312,1 : 583,68 : 250 : 110), F (1562,5 : 350,12 : 730,1 : 324,78 : 50), G (1562.5 : 350.12 : 730.1 : 324.78 : 70), H (1562.5 : 350.12 : 730.1 : 324.78 : 90) dan I (1562.5 : 350.12 : 730.1 : 324.78 : 110). The results showed that there was an effect of macro and micro fertilizer ratio on number of leaf, number of chorophyll, and leaf area Brassica olerace. The ratio of pupuk NPK (1562,5) : CaSO4 (350,12): MgSO4 (730,1) : K2SO4 (324,78) : 90 Soluble macro mix was recommended as an alternative to substitution AB mix fertilizer.
