Nepenthes is a genus of carnivorous plants in the monotypic family Nepenthaceae. The genus comprises around 130 species, numerous natural and many cultivated hybrids. Plants generally need fertilizer to promote their growth and development. However, in their original habitat Nepenthes forms pitchers under nutrition starvation condition. This study aimed at determining the effect of fertilization on the growth and pitcher formation of Nepenthesx ventrata. Experiment was conducted at Suska Nursery, Caringin, West Java, Indonesia from February until June 2011. Plants were treated with the N: P: K, 60-30-30, 32-10-10 and 10-55-10 and at different concentrations ie, 0.5, 1 and 2 g L-1. Fertilizer was applied weekly to the growing media. Weekly observations were conducted on number of leaves, plant height, time of pitchers initiation, the number of pitchers and pitcher diameter and length. Daily temperature, relative humidity and EC (electrical conductivity) of the growing media were also recorded during the experiment. The results showed that combination of fertilizer with different composition and concentration did not affect Nepenthes growth and development. Application of fertilizer resulted in smaller size pitchers compared to control plants. Future research on Nepenthes should be conducted in a longer period since Nepenthes is a slow growing plants.Keywords: Nepenthesx ventrata, fertilizer, pitcher plant

Kaempferiaparviflora (Zingiberaceae family) has a potency to be developed for a new medicinal plants in Indonesia. One of problems in its cultivation is the lack of planting material availability due to the long dormant period. The objectives of this research were to study the effect of various concentrations of BAP and ethephon, and also the effect of the prior growing condition to the dormancy breaking and shoot growth of K.parviflora rhizome. Two separate experiments were applied for two lots of rhizomes namely Cikabayan and Pasir Sarongge lots. Each experiment was arranged in completely random design with 2 factors. Experiment-1 used 4 concentrations of BAP (0, 50, 100, and 150 ppm) as the first factor. While, experiment-2 used 5 concentrations of ethephon (0, 200, 400, 600 and 800 ppm) as the first factor. The second factor in both experiments were prior shade condition at 55% artificial shading and natural shading. A rhizome without soaked application (control) and a rhizome with soaked by aquadestilata without PGRs (0 ppm) were used as compared items. Data was analyzed with ANOVA. Combined Analysis of Variance and t-test were performed in order to compare between 2 lots. Result showed that concentration of BAP until 150 ppm and concentration of ethephon until 800 ppm were not effective to stimulate bud induction time. Meanwhile, rhizome from 55% artificial shading had a shorter periode of dormancy than the natural shading. In the addition, plants from Pasir Sarongge rhizomes lot had more plant number, plant height, leaf number, leaf length, and leaf width than Cikabayan rhizomes lot.

Budidaya Tanaman Akar Wangi (Vetiveria zizanioides (L.) Nash) dalam Wadah: Pengaruh Jenis Media Tanam dan Jumlah Bibit Resti Putri Septyani; Sintho Wahyuning Ardie; Slamet Susanto

Penelitian ini bertujuan untuk mengetahui pengaruh komposisi media tanam dan jumlah bibit dalam budidaya tanaman akar wangi (Vetiveria zizanioides) secara hidroponik menggunakan polybag terhadap pertumbuhan tanaman akar wangi varietas Verina 2. Penelitian dilakukan di rumah kaca Kebun Percobaan Cikabayan Bawah, IPB dengan elevasi 240 m di atas permukaan laut (dpl) mulai dari bulan November 2012 hingga Juli 2013. Penelitian disusun berdasarkan rancangan kelompok lengkap teracak (RKLT) dengan dua faktor dan lima ulangan. Faktor pertama adalah komposisi media tanam (v/v) yang terdiri atas tiga taraf, yaitu 100% arang sekam, arang sekam : styrofoam (2:1), dan arang sekam : styrofoam (1:1). Faktor kedua adalah jumlah bibit dalam satu polybag yang terdiri atas dua taraf yaitu satu bibit dan dua bibit. Hasil penelitian menunjukkan bahwa interaksi antara komposisi media tanam dan jumlah bibit per polybag tidak berpengaruh nyata terhadap pertumbuhan tanaman dan pertumbuhan akar tanaman akar wangi. Tanaman yang ditanam pada media arang sekam : styrofoam (1:1) memiliki jumlah daun, jumlah anakan, jumlah akar, panjang akar, kandungan klorofil, dan karotenoid yang lebih tinggi dibandingkan tanaman yang ditanam pada media lainnya. Penanaman dua bibit per polybag menghasilkan jumlah daun, jumlah anakan, bobot basah dan kering tajuk, dan jumlah akar yang lebih tinggi dibandingkan dengan satu bibit per polybag. Hasil tersebut menunjukkan bahwa penanaman dua bibit per polybag pada media arang sekam : styrofoam (1:1) menghasilkan pertumbuhan vegetatif dan pertumbuhan akar terbaik pada tanaman akar wangi.
