Abstract

Growth pattern and nutrient uptake of Echinacea purpureaEchinacea purpurea or purple cone flower, belongs lo Aslcraceac family which grown naturally in Noth America. The plant known as is Ihe number one Immune herbs in the world, since it has a greal potential lor improving and developing leukocyte cell activity. Recently, Echinacea has been evalualcd/tcsled as adjuvant in cancer therapy, AIDS and chronic exhaustion. Echinacea purpurea is more potential for immunity improvement lhan those of other herbal medicine. Therefore, the study on its growlh rale, growth pattern, and nutrient uptake in a new tropical environmental condition is very important in order lo suppot its cultivation technology, lo identify the growth pattern, growlh rale, nutrient uptake, and simplisia quality. A ield trial had been conducted in Cipanas at 1 100 m above sea level (asl) in 1999-2000. Plot size was 4x3 m, and plant spacing was 50 x 40 cm. Ten samples was taken from each growth stage of the plants. The growth stages were (I) vegetative I (VI) at I month alter planting (map), (2) vegetative 2 (V2) al 1 .5 map, (3) generative I (Gl) at 2 0 map, (4) generative 2 (G2) at 2.5 map. (5) generative 3 (G3) at 3.0 map. and (6) generative 4 (G4) al 3.5 map. The results of the research showed thai growth rate, nutrient uptake of N, P. K. Mg. and S linearly increased in line with Ihe increase of plan! ages The highest dry weight accumulation was found on aerial part of plant (slem I leal), and the lowest was occurred on root pat. The amount of dry weight accumulation was 75.72 g/plnul. and nutrient uptake oIN, P. K.Ca, Mg, and S. respective!) was 1529.1. 1 40.01. 1943.25, 654.59. 358.66. and 88.57 mg/plant.

Abstract

Productivity of Talinum paniculatum Gaertn. on several of organ ics matter compositionTalinum paniculatum Gaertn. is a tuber producing crop To produce (he optimum yield Ihe crop needs the soil with good physical properties and fertility The soil conditions may be improved by applying organic matter. An experiment was conducted to evaluate Ihe effect of the composition of organic matter (compost, stable manure and casting) on tuber yield of talinum. The experiment was carried out at the Research Institute for Spice and Medicinal Crop. Bogor. from September 1996 to September 1997. in a randomized block designed with four replications. The treatments evaluated were Ihe ratio of soil organic matter, i.e (I) soil, (2) soil + stable manure (3:1); (3) soil + casting (3:1); (4) soil + bamboo leaf compost (3:1): (5) soil + casting + bamboo leaf compost (6:1:1); (6) soil + stable manure + bamboo leaf compost (6:1:1); (7) soil + stable manure ♦ casting (6:1:1). Seedling was planted in polybag containing 20 kg of tested media Plants were applied with I g urea, 3 g TSP and 3 g KCI/polybag as basal dressing, while 2 g of urea was applied as top dressing at 3 months after planting. Plants were harvested at I year after planting Result of experiment found thai 3 kinds of organic matter treatments could increase Ihe number, fresh weight, and dry weight of tuber The highest tuber production were 165.40 g fresh/plant and 26.75 g dried/plant resulted from soil and casting treatment (3 I).

Abstract

Tanaman mengkudu tanpa biji merupakan tanaman langka sehingga untuk mengantisipasi kelangkaan tanaman ini perlu pengembangan teknologi perbanyakan. Pengembangan mengkudu tanpa biji tidak dapat melalui perbanyakan generatif, tetapi harus melalui perbanyakan vegetatif. Perbanyakan vegetatif yang prospektif adalah menggunakan metode penyambungan pucuk. Tujuan penelitian ini adalah untuk mendapatkan umur bibit batang bawah yang dapat menghasilkan bibit mengkudu tanpa biji bervigor tinggi. Penyambungan pucuk mengkudu tanpa biji telah dilakukan di KP. Cimanggu sejak Januari sampai Desember 2012 menggunakan batang atas mengkudu tanpa biji yang entresnya disimpan selama satu hari. Batang bawah yang diuji adalah lima umur batang bawah, yaitu umur 3, 4, 5, 6, dan 7 bulan, diulang lima kali. Rancangan yang digunakan adalah Rancangan Acak Kelompok. Parameter yang diamati adalah daya tumbuh, jumlah daun, dan panjang tunas. Hasil penelitian menunjukkan bahwa tingkat keberhasilan penyambungan mencapai 68%. Berdasarkan jumlah daun dan panjang tunas, benih mengkudu tanpa biji optimal dipindah ke lapang dan produksi pada umur tiga bulan setelah penyambungan. Benih yang dihasilkan mempunyai vigor tinggi pada umur tiga bulan setelah penyambungan.Â
