Pemberian Larutan Hara untuk Budidaya Tanaman Akar Wangi (Vetiveria zizanioides (L.) Nash) Menggunakan Teknologi Hidroponik Sistem Terapung (THST)

Abstract

The objective of this experiment was to determine the effect of concentration of nutrient solution on growth and yield of vetiver (Vetiveria zizanioides (L.) Nash) Verina 2 variety using Hydroponic Floating System Technology (HFST). This experiment that is a continuation of previous experiment. The experiment is based on a randomized complete block desing which consists of two experiments: (1) a plant that has not been done cutting the roots (3 replicates), (2) plants that have been done cutting the roots (6 replicates), with one factor and three-level: nutrient solution concentration of 200 ppm, nutrient solution concentration of 400 ppm and nutrient solution concentration of 800 ppm. The results showed that the concentration of the nutrient solution had significant effect on plant height, number of tillers, number of new saplings, canopy dry weight in plants that have not done cutting the roots, and root fresh weight in plants that have been done cutting the roots. Treatment of nutrient solution concentration of 200 ppm resulted that the growth of plants do not develop properly. Vetiver plants that grown with the provision of nutrient solution concentration between 400 ppm to 800 ppm acquire a better canopy growth and root development of plants, therefore THST can be applied to the cultivation of vetiver on the concentration of the nutrient solution so it could produce a better canopy growth and root development.
