Abstract

Warnita, Herawati N. 2017. Effect of Naphthalene Acetic Acid (NAA) and foliar fertilizer concentration on the growth of ornamental plants Anthurium ‘wave of love’ (Anthurium plowmanii). Pros Sem Nas Masy Biodiv Indon 7: 50-55. One species of ornamental plants which much in demand because of the shape of its leaves that beautiful and attractive is Anthurium ‘wave of love’. Anthurium wave of love (Anthurium plowmanii) has unique characteristics with the wavy leaf edge. To enhance the growth of this plant can be done with NAA and foliar fertilizer. The purpose of this study was to obtain the best concentration of NAA and foliar fertilizer for growing the ornamental plant of Anthurium wave of love. The study started from March to July 2015 in the Housing Unand, Ulu Gadut, Padang. The materials used in the form of seedlings of the ornamental plant of Anthurium wave of love, the growing media consisted of soil, sand and manure in the ratio of 1:1:1 (v/v). The experiment was a factorial with two factors which in a completely randomized design (CRD) with four replications. The first factor was NAA concentration consisted of 0 and 20 ppm, while the second factor was the concentration of foliar fertilizer consisted of 0, 1, 2, and 3 g/L. The data were analyzed by analysis of variance followed by HSD test at a test level of 5%. The parameters observed included plant height, leaf number, the length of the longest leaf, the width of the widest leaf, the number of roots and the length of the longest root. The results showed NAA treatment with a concentration of 20 ppm and foliar fertilizer 1 g/L is the best for the growth of plant height, the length of the longest leaf, the width of the widest leaf, and the length of the longest root.
