Pertumbuhan krisan pot, Chrysanthemum morifolium Ramat var. Sheena yellow pada berbagai nilai EC, Electrical conductivity

Abstract

Chrysanthemum sp. were cultivated flowers as a member of Asteraceae famili which need place, water, nutrition and oxygen. The nutrition were obtained from fertilizing both macro and micro nutrients. The aims of the research were to see the growth of pot mum (Chrysanthemum morifolium Ramat var Sheena yellow ) at EC value from 0.5 mS/cm to 2.5 mS/cm and to obtain the most optimum EC value for the growth of pot mum. This research used randomized one factor rendomized complete design, i.e EC value fertilizer with 10 repetition for each. Treatment CaNO3, KNO3, MgSO 4 , and diamonium Phosphate (DAP) fertilizer were used as control. The fertilizer that used as a treatment was AB mix liquid fertilizer from Parung Farm with EC value 0.5 mS/cm, 1 mS/cm, 1.5 mS/cm, 2 mS/cm and 2.5 mS/cm. The pot mum with EC value treatment 2.5 mS/cm (E) showed the best growth level in high plant, number of internode, number of leaf, flower diameter, total fresh weight and total dry weight. The pot mum with EC value treatment 1.5 mS/cm (C) showed the best growth level in width of leaf, length of leaf and stalk diameter.
