Budidaya Tanaman Akar Wangi (Vetiveria zizanioides (L.) Nash) dalam Wadah: Pengaruh Komposisi Media Tanam dan Jumlah Bibit.

Abstract

The objectives of this experiment were to determine the effect of media composition and the number of seedlings planted on the growth of hydroponically grown vetiver (Vetiveria zizanioides). Vetiver ‘Verina 2’ variety was grown in polybags in a greenhouse of the Cikabayan Bawah Experimental Farm (240 m above sea level) started from November 2012 to July 2013. This experiment was arranged in a randomized complete block design with two factors and five replications. The first factor was media composition (v/v), consisted of three levels i.e. 100% charchoal husk, charcoal husk : styrofoam (2:1), and charcoal husk : styrofoam (1:1). The second factor was the number of seedlings in one polybag consisted of one seedling and two seedlings. The results showed that there were no interaction effects of media composition and number of seedlings planted to plant growth and root growth of vetiver. Plants grown in charcoal husk : styrofoam (1:1) medium had significantly higher number of plants per cluster, higher number of leaves, higher chlorophyll and carotenoid contents, higher number of roots, and longer primary roots than those in other media compositions. Planting two seedlings per polybag resulted in higher number of plant per cluster, higher number of leaves, higher shoot fresh and dry weight, and higher number of roots than one seedlings per polybag. These results showed that planting two seedlings in polybag containing charcoal husk : styrofoam (1:1) resulted in the best vegetative growth and root growth of vetiver.
