Full text linkThis study was conducted to determine the effect of growth hormones and mycorhyza application on the growth of ramin cuttings. A Completely Randomized Design with 5 replicates was used in this study. The experiment consisted of two stages i.e hormon treatments (control, Rapid root, Root Up, IBA 250 mg/l, IBA 500 mg/l, IBA 1000 mg/l), Fusarium and mycorhyza applications. The result showed that the highest number of root was obtained from Root Up (12,83 cm), while the lowest was from Fusarium treatments (4,67 cm). IBA 250 mg/l enhanced the number of roots and the length of root significantly but not stimulate the development of new leaf. While mycorhyza application improving the growth of the new leaf and the root development of ramin

Full text linkABSTRAK
The experiment was carried out to study the effect of topping and fertilizer application on\u27the productivity increasing of peanut var. Gadjah and this work was conducted at the experimental garden of Agriculture Training and Research Development (ATRD) Gadjahmada University. The peanut crops were fertilized with Urea, TSP, and ZK at different concentrations.
The result of investigations showed that the pruning tops increased the number of branches, mature pods, number of nuts and number of flowers grew up to mature pods pods per plant. However, the height of peanut with topping shorter than that of control. The fertilizers only affect ed the fresh weight of the leaves, stems and roots. Both topping and fertilizing did not affe the dry weight of pods and nuts.

Pertumbuhan Kaempferia rotunda L. dengan Perlakuan Variasi Jumlah Umbi Semu dan Penambahan Pupuk Organik
Full text linkKaempferia rotunda, usually called as temu putih is belonging into Zingiberaceae family.This plant has been used as traditional medicine for curing diarrhoe and disentry.Objective of the study was to determine the effect of pseudo tubers number and organicfertilizers on the productivity of K. rotunda. Research was conducted in TreubLaboratory, Research Centre for Biology LIPI, Bogor, from July 2002 until April 2003.The experiment was arranged in a factorial Randomized Block Design. The treatmentsconsisted of two factors, i.e the first factor were number of pseudo tubers (0, 2 and 4)and second factor were organic fertilizers (soil, goat manure and compost).The result of the exsperiment showed that both factors, i.e number of pseudo tubers andorganik fertilizers significantly affect productivity of K.rotunda. The effect of goatmanure more dominant than compost. The interaction of those two factors significantlyinfluenced number of leaves and fresh weight of rhizome. The best results was on thecombination treatment of two pseudo tubers and goat manure which had the highestvalue on all peubahs observed which were increased growth and yield of K. rotundasignificantly
Respon Pertumbuhan Bibit Picrasma javanica Blume terhadap Intensitas Naungan dan Media Tanam
Full text linkStudy on the growth response of Picrasma javanica Blume seedling to different shading intensities and medium was conducted at the Experimental Garden of Treub Laboratory, Research Centre for Biology, LIPI from June to December 2007. The research was arranged using Factorial in Completely Randomized Block Design with 2 factors and 5 replications. The first factor was shading intensities which were 0% (N0, without shading, average light intensities 39300 lux), 25% (N1, average light intensities 16430 lux), and 50% (N2, average light intensities 5867 lux), respectively and the second factor was medium (combinations of soil: manure:compost) with 6 levels were M1= 1:0:0, M2= 1:1:1, M3= 1:1:2, M4= 3:1:1, M5= 1:2:1, and M6= 2:1:1. The result showed that the N0 treatment (without shading) resulted the best growth response of Picrasma javanica Blume seedling, as showe in all parameters observed (plant height 27.11 cm; leaf number 15.57; diameter of trunk 4.32 mm; and root length of 15.97 cm, shoot dry weight of 1.762 g, root dry weight of 0.688 g and seedling quality index of 0.277). The growth media treatment of M5 (1-soil:2 manure:1 compost) showed the positive response on the growth of seedling better than other treatments and different with control (M1, soil media), with parameters were observed which was plant height 25.05 cm (M1= 19.10 cm); leaf number 16.53 (M1= 9.20); diameter of trunk 3.89 mm (M1= 2.76 mm); root lengh 15.23 cm (M1= 12.71 cm); shoot dry weight 1.58 g (M1= 0.663 g); root dry weight 0.51 g (M1= 0.221 g) and seedling quality index 0.220 (M1= 0.089). The combination treatment of N0 (without shading) and media M5 (1:2:1) gave the best response on the growth of Picrasma seedling (plant height 36.14 cm; leaf number 28.2; diameter of trunk 4.7 mm; and root length 16.7 cm, shoot dry weight 3 g and root dry weight 0.92 g)

PENINGKATAN PRODUKSI DAN PERBAIKAN UKURAN UMBI KENTANG HITAM (Plectranthus rotundifolius (Poir.) Spreng) MELALUI TEKNIK BUDIDAYA SEBAGAI UPAYA KONSERVASI
Full text linkA decrease of the role of a species in the society culture can lead to scarcity and even the extinction of that species. Along with the government program to diversify food, it can be repopularized the underutilized carbohydrate source potential plants with the aim as the plant conservation efforts. Related to this, the hausa potato (Plectranthus rotundifolius) can be an alternative food source for the people who occupy arid areas. Hausa potatoes not only serve as a carbohydrate source with low glycemic index, but also rich in essential vitamins and minerals. Information on cultivation techniques become important things that need to be prepared within the framework of development. The study was conducted to answer questions regarding cultivation techniques that need to be done to improve the quality of the hausa potato crop in the market. The study was designed based on a randomized block design (RCBD) two factors, four hausa potato accessions and four types of cultivation techniques (four hausa potato accessions: Nganjuk, Sangian, clone 6G and O3; and four types of cultivation techniques: stockpilling, prunning, mulce, and lifting). Every treatment consist of four replications with three plants/replications. Observations were made on growth and yield parameters. The results showed that the different hausa potatoes accession need different cultivation techniques to improve the yield and tuber size. The use of rice straw mulch on hausa potato cultivation can improve the size of hausa potato tubers in the rainy season
Studi Persebaran dan Pemanfaatan Gayam [Inocarpus fagifer (Parkinson ex Zollinger) Fosberg] di Daerah Istimewa Yogyakarta
Full text linkStudy on ‘Distribution and Utilization of gayam [Inocarpus fagifer (Parkinson ex Zollinger) Fosberg] on several locations in Special Territory of Yogyakarta (DIY)’ was carried out from 15 until 20 September 2010. The method of this study was Purposive Random sampling and interview with local communities. The results showed that the DIY provincy was location of natural distribution of gayam. The population of gayam from each location is different, depend on soil condition and communities activities. The communities in Bantul, Sleman and Kulon Progo regencies have conserved gayam, with maintenanced gayam seedling which grew under gayam tree. Gayam grow well in sandy loam soil and silty loam soil with pH from acid till neutral. Generally this plant grow in moisture soil i.e. near water resource, a long of river bank and cannal. The chemical content of gayam seed consist of 74.87% carbohydrate, 11.63% protein, and 2.15% fat. The seed from Banjar Asri, Kulon Progo have the highest of carbohydrat (77.70%) from fresh fruit. Gayam is multipurpuse plant i.e. food, fodder, fuel wood, erosion control, herbal pesticides, and habitat for bird and bet

UPAYA MENINGKATKAN PRODUKTIVITAS SAMBILOTO DENGAN PENAMBAHAN PUPUK NITROGEN
No full textA study of nitrogen fertilizer treatment on sambiloto plant (Andrographis paniculata Nees) to promote the productivity was carried out. The result indicated that ZA and Urea at 0.5 g per pot increased significantly the height of plants, the number of leaves, the number of branches and the dry weight of plants. There is no significant difference effect onthe use of ZA and Urea, however the use of low - as well ashigh dose of ZA tend to increase the number of leaves and the dry weight of plants
