The Influence of Plant Age on Growth and Quality of Plant Nilam Oil (Pogostemon Cablin Benth.) under the Improvement of Palm Oil Plant

Abstract

This study aims to determine the effect of plant age on the growth and quality of patchouli plant essential oil (Pogostemon cablin Benth) under oil palm plantations. Experiments using a randomized block design were arranged factorially with two factors consisting of 16 treatments with six replications. P1U1 = NPK fertilizer 20 g with 4 months plant life, P1U2 = NPK 20 g fertilizer with 5 month plant life, P1U3 = NPK 20 g fertilizer with 6 month plant life, P1U4 = NPK fertilizer 20 g with age 7 months, P2U1 = Fertilizer patchouli waste compost 150 g with 4 month old plant, P2U2 = 150 g patchouli compost fertilizer with 5 month old plant, P2U3 = 150 g patchouli compost fertilizer with 6 month old plant, P2U4 = 150 g patchouli compost with age plant 7 months, P3U1 = Ciseritic fertilizer 30 g with 4 month old plants, P3U2 = Ciserit fertilizer 30 g with 5 month old plants, P3U3 = Ciserit fertilizer 30 g with plants aged 6 months, P3U4 = Ciserit fertilizer 30 g with 7 month old plants, P4U1 = NPK Fertilizer 10 g + patchouli compost 75 g + kiserit fertilizer 25 g with 4 month old plant, P4U2 = NPK fertilizer 10 g + compost patchouli 75 g + kiserit fertilizer 25 g with plant age 5 months, P4U3 = NPK fertilizer 10 g + patchouli compost 75 g + kiserit fertilizer 25 g with age plants 6 months, P4U1 = NPK fertilizer 10 g + patchouli compost 75 g + 25 g kiserit fertilizer with 7 month old plants. The variables observed included plant height, number of branches, number of leaves and oil content. The results of the research data were statistically analyzed using analysis of variance with further DMRT testing at the level of 5%. The best plant growth on 150 g patchouli compost with 7 months of age, 10 g NPK fertilizer treatment + 75 g + Kiserit compost 25 g produces the highest levels of essential oils.
