Daftar Isi:
- Patchouli (Pogostemon cablin Benth) is a plant known to produce essential oils, and is also an important foreign exchange earner for Indonesia. However, the use of superior clones and appropriate fertilizers tend to drastically increase product yield. This research aims to obtain species with the best response to urea fertilizers, and the right dosage for optimum performance. The study was conducted at the Politeknik Negeri Lampung’s teaching farm from December 2018 to May 2019, using a factorial randomized block design (RBD). This consisted of two treatment factors, including the 2 level clone consisting of The NPL 9 and Lhokseumawe, and 4 level urea dose control at, 250 kg.ha-1, 300 kg.ha-1, and 350 kg.ha-1. Furthermore, variables observed included plant’s height, bough, diameter, number of leaves, stalk angle, chlorophyll content, wet weight of plant, wind dry weight of plant, and yield. The results shows NPL 9 clone has a superior appearance and the urea value of 350 kg.ha-1 was attributed as the optimal dose, yielding a 2,3% increase compared to the control treatment.
- Patchouli (Pogostemon cablin Benth) is a plant that produces essential oils and important foreign exchange earner for Indonesia. Using superior clones with the right fertilizer application will increase the yield of patchouli oil. The research aims to obtain patchouli plants that have the best response of urea fertilization application and optimum dosage of urea for patchouli plant growth. The study was conducted at the Politeknik Negeri lampungâ€TMs teaching farm in December 2018 until May 2019. The experiment was conducted using a factorial randomized block design (RBD), consisting of two treatment factors, namely the type of urea clone. The first factor is the type of clone consisting of 2 levels, namely NPL 9 clone and Lhokseumawe clone. The second factor is the treatment of urea doses consisting of 4 levels, namely control, 250 kg.ha-1, 300 kg.ha-1, and 350 kg.ha-1. Variables observed included plantâ€TMs height, bough, diameter, number of leaves, stalk angle, chlorophyll content, wet weight of plant, wind dry weight of plant, and yield. The results of research showed NPL 9 clone had a superior appearance and 350 kg.ha-1 of urea dose was the optimal dose compared to other doses and could increase patchouli yield 2,3% compared to the control treatment.
