Abstract

Pengaruh ukuran dan perlakuan bibit terhadap petumbuhan dan produksi umbi iles-ilcs (Amorphophallus oncophyllus) ditcliti di Bogor dan Cikampek tahun 1993 1995, yang dilakukan dalam dua percobaan. Pada percobaan petama dipelajai pengaruh ukuran bibit utuh dan pada percobaan kedua pengaruh ukuran dan pcmbclahan bibit terhadap petumbuhan dan produksi umbi. Bibit utuh berasal dari umbi batang dengan ukuran 200 dan lOOg, seta umbi tetas dengan 5 dan 2.5g, sedangkan pcmbclahan bibit berasal dai umbi batang ukuran 200g, yang dibelah menjadi 2 bagian (a lOOg), 4 bagian (a SOg) dan 8 bagian (a 25g). Bibit dai pcrlakuan-perlakuan tersebut disemai di bak pasir di rumah kaca dan petumbuhannya diamati pada umur 1-2 bulan. Bibit yang bctunas normal ditanam di lapangan. Untuk percobaan percobaan petama (bibit utuh), bibit-bibit yang bctunas normal di tanam di Bogor dan Cikampek, sedang percobaan kedua (bibit dibelah) ditanam hanya di Bogor. Kedua percobaan tersebut dirancang secara acak kelompok dengan 5 ulangan. Parameter yang digunakan untuk menilai pengaruh perlakuan adalah tinggi tanaman dan diameter batang, panjang daun dan produksi umbi pada umur 6 dan 18 bulan setelah tanam, untuk bibit utuh dan 6 bulan untuk bibit yang dibelah. Hasil penelitian dapat disimpulkan sebagai berikut. Dai percobaan pertama (bibit utuh) temyata ukuran bibit tidak berpengaruh terhadap persentase pertunasan maupun petumbuhan di lapang. Komponen pertumbuhan dan hasil umbi sangat dipengaruhi oleh lokasi penanaman dan ukuran bibit. Komponen pertumbuhan, kecuali diameter batang, seta produksi umbi di Bogor nyata lebih tinggi dari pada di Cikampek. Pada bibit utuh, ukuran bibit 200g menghasilkan komponen petumbuhan dan produksi umbi paling tinggi dan berbeda dengan ukuran- ukuran lainnya, makin kecil ukuran bibit makin kecil nilai komponen petumbuhan dan produksi umbi. Dai percobaan kedua (pembelahan umbi) diperoleh bahwa pembelahan umbi dai 200g sampai 25g tidak mempengaruhi pertunasan di rumah kaca maupun tanaman yang tumbuh di lapangan. Tinggi batang lebih kecil pada bclahan 25g, diameter batang pada belahan 50g dan produksi umbi pada bclahan lOOg dibanding bibit utuh 200g. Berdasarkan data tersebut, untuk memproduksi bibit secara masal, umbi dapat dibelah sampai ukuran 25g dan dalam waktu 6 bulan dapat diperoleh umbi sebcrat + 200g dan umbi ini dapat menghasilkan umbi sekitar 1 kg umbi/batang dalam waktu 6 bulan.Kata kunci: Amorphophallus oncophyllus. ukuran bibit, produksi ABSTRACTEffect of seed size and seed treatment on the growth and yield of Amorphophallus oncophyllusEfect of seed size and seed treatment on the growth and yield of Amorphophallus oncophyllus was studied in Bogor and Cikampek from 1993 to 1995, in two expeiments. The irst experiment studied the efect of the size of sound seed, and the second studied the efect of size and splitting seed on die growth and yield of tuber. In the first experiment the sound seed used were the true tuber with the size of 200 and lOOg and bulbil with the size of 5 and 2.5g. In the second expeiment, the tuber of 200g were splined into 2 parts (a lOOg), 4 parts (a 50g) and 8 parts (a 25g). The seeds were irstly planted in sand boxes in die glass house and evaluated for their sprouting at I -2 month ater planting. For the irst expeiment the normal sprouted seeds were planted in the ield in Bogor and Cikampek, while for the second expeiment, the normal sprouted seeds were planted in Bogor The two experiments were designed as a randomized block in 5 replicates. The parameters used for evaluating the effect of treatments were plant height, stem (pseudo-stem) diameter, leaf length and yield of tuber at 6 and 18 months ater planting for the irst and 6 months for the second expeiment. Results of the studies are summarized as follows. From the irst expeiment (sound seed) it was sevealed that seed size neither afected spronting percentage nor plant stand in the ield. The growth components and tuber yield were afected by planting location and size of seed. The growth components, except stem diameter, and tuber yield in Bogor significantly higher than those in Cikampek. From the second experiment it was shown that splitting seed rom 100 to 25g neither afected the sprouting percentage in the glass house nor plant stand in the ield. Plant height signiicantly decreased at the size of 25g, stem diameter al 50g and tuber yield at lOOg. Based on the data, for mass production of seed tuber, the tuber could be splined into 25g. Within 6 months the seed may produced a tuber of 300g and the tuber could produced 1 kg tuber within 6 months.Key words : Amorphophallus oncophyllus. seed size, tuber yield

Abstract

Effect of KS, AS, and urea Compositions and N-dosages on quality of Besuki cigar tobaccoThe experiment was conducted on loamy soil at Ajung, Jember from June 1999 to March 2000. The objective was to study the effect of Kalk Salpetcr (KS), ammonium sulphates (AS), and urea compositions and N-dosages on quality of Besuki cigar tobacco. The treatment consisted of two factors i.e. fertilizer composition and N dosages. The first factor was 5 levels of fertilizer composition, i.e. KS; KS(50%)+AS (50%); AS; KS(50%)+urea (50%) and uea. The second factor was 3 level of N-dosages, i.e. 60, 90 and 120 kg N/ha. The treatments were arranged in factorially randomized block design with 3 replications. Planting space was double row (100+70) cm x 40 cm wiUi a population of 168 plants per plot. Results showed thai AS or urea as side dressing fertilizer was not significantly different from KS fertilizer on the percentage of warpper (dekblad) and binder (omblad) quality, leaf thickness, and burning capacity. But especially on organolcptic AS or urea as side dressing fertilizer decreased organoleptic quality, i.e. the taste was bitter and irritating, less aromatic, bad smell, ash color changed from white to black, and decreased ash resistance. All of those characteristics were not desirable in cigar factory. Based on organolcptic quality we suggest the following : (I) AS and urea should be used as a starter only not as side dressing fertilizer, (2) KS fertilizer still perform Ihe best result (3) recommended N-dosage was 60 kg N/ha.

Abstract

The influence of material bulk density and duration of distillation on the yi eld and characteristic of Melaleuca bracteata oilMelaleuca bracteata belongs to Myrtaceae family which is grown wildly in Australia and Quensland. The oil is produced from Ihe leaves and (wigs by distillation and is used in fragrances industry. The oil content of leaves and twigs range between 0.4 to 1.0% with metil eugenol as the major component (70-80%). Because of its high metil eugenol content M. bracteata oil can be used to control fruil flies The experiment was carried out to evaluate the influence of material bulk density in the distillation vessel and duration of distillation on the yield and charac¬ teristic of the oil produced. Material used was (he leaves and twigs of M bracteata from the experimental garden of the Research Institute for Spice and Medicinal Crops. Manoko, Lembang (1200 in above the sea level). The experiment at 1993 was designed as completely randomized design, arranged factorially with three replications. The result showed that the optimum distillation condition was 1 56 g/l material bulk density in the vessel and 3 hours distillation. Such distillation condition produced 1.09 % oil yield with (he characteristics as follow speciic gravity I 0263, refractive index 1 5296, optical rotation -3.3°, solubility in 70% cthanol 1 : 1, methyl eugenol content 86.1%, acid number 0.56, ester number 15.4 and ester number after acetylation 39.3. Referring to Australia oil, the Indonesian M bracteata oil has higher value of esther number both before and after acetylation.

Abstract

The effect of soybean planting methods and dosage of nitrogen fertilizer for cotton on pest development and cotton yieldThe effect of soybean planting methods and dosage of N fertilizer for cotton on pests development and cotton yield was studied in Tanggungan, Pucuk, lanongan from July 1997 to March 1998 on wet land previousl grown with rice plant rice. Split plot design in three replicates was used, planting system of soybean (sowed and planted in a hole) was the main plot and the rate of N fertilizer (30 kg N/ha, 60 kg N/ha and 90 kg N/ha) was the sub plot. Urea and ZA were used as source of N; SP36 for P20, and KCI for KjO. The rate of SP36 was 50 kg/ha and KCI was 50 kg/ha. One third of the full dosage of N (ZA) and the full dosage of P]Oj (SP36) and K20 (KCI) were applied at the time of planting While 2/3 of N were applied 6 weeks after planting. Cotton variety used in this study was ISA 205 A and soybean was Willis. Cropping pattern was 2 rows of cotton and 5 rows of soybean. Planting space of cotton was (190) 60 cm x 30 cm (2 plants per hole), hence the population was 53 280 plants per hectare. Plant spacing of soybean was 30 cm x 20 cm (2 plant per hole), hence the population was 200 000 plants per hectare. Parameters evaluated were the growth of cotton plant (height and canopy); component of yield (vegetative and generative branch, square shedding and number of bolls), and population of pest. The results showed that increasing the dosage of N from 30 (50% of the recommended dosage) to 60 kg (recommended dosage) and 90 kg (150% of the recommended) resulted in increased population of H. armigera from 12.33 insect to 18.77 and 17.00 insect, Erias sp. from 93.17 to 51.50 and 51.50 and S. bigutulla fom 103.5 to 102.50 and 122.30 insects per plant. Increased population of pest was followed by increased frequency of spraying from 2.50 to 3.50 and 3.67 times. Application of 30 kg N/ha decreased the population of// armigera, Earias sp. and 5. biguttula. however, the highest yield of cotton (1 580.16 kg/ha) was gained by applying 60 kg N/ha. Soybean planted by broascasting method had greater effect on cotton and soybean yields than dibbling method.

Abstract

Sugarcane (Saccharum officinarum L.) is propagated vegetatively using stem cuttings. Plant propagation can utilize tissue culture techniques because it offers a faster propagation time than conventional methods, need less mother plants and labor, planting is not influenced by the season, and produce pathogen-free guaranteed seedlings. This study aims to determine the optimal type of explant for shoot multiplication of six sugarcane genotypes. The study was conducted at the Tissue Culture Laboratory, Plant Cell Tissue Biology Group, Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development, Bogor from May 2015 to June 2016. Explants from six genotypes of sugarcane (PS 881, PS 865, GMP 3, TK 386, PSJK 922, and PS 862) were grown on regeneration media based on explant type treatments (one shoot, two shoots, and three shoots per explant) that were subcultured every three weeks. Subcultures were conducted up to nine times, then observations of survival rate, shoot regeneration rate, number of new shoots, shoot height were made on the third, sixth, and ninth subcultures. The results showed interaction between genotypes and explant type were not significantly different except to the shoot regeneration in the sixth subculture. Each genotype had different multiplication rate, and PSJK 922 produced the lowest survival explant, shoot regeneration, and number of new shoot in the ninth subculture. Two shoots explant were the optimal type of explant for in vitro shoots multiplication with 4 new shoots per explant in the ninth subculture.Keywords: frequent subculture, micropropagation, one shoot explant, two shoots explant, three shoots explant AbstrakTebu (Saccharum officinarum L.) umumnya diperbanyak secara vegetatif menggunakan stek batang. Perbanyakan tanaman dapat memanfaatkan teknik kultur jaringan karena memiliki keunggulan di antaranya, waktu perbanyakan lebih cepat dari metode konvensional, tidak memerlukan tanaman induk dan tenaga kerja dalam jumlah banyak, penanaman tidak dipengaruhi musim, serta bibit yang dihasilkan lebih terjamin bebas patogen. Penelitian ini bertujuan menentukan jenis eksplan yang optimal untuk multiplikasi tunas in vitro enam genotipe tebu. Penelitian dilakukan di Laboratorium Kultur Jaringan, Kelompok Peneliti Biologi Sel dan Jaringan, Balai Penelitian dan Pengembangan Bioteknologi dan Sumberdaya Genetik Pertanian, Bogor pada Mei 2015 hingga Juni 2016. Eksplan dari enam genotipe tebu (PS 881, PS 865, GMP 3, TK 386, PSJK 922, dan PS 862) ditanam pada media regenerasi berdasarkan perlakuan jenis eksplan (satu tunas, dua tunas, dan tiga tunas per eksplan) yang disubkultur setiap tiga minggu. Subkultur dilakukan hingga sembilan kali, dan pengamatan daya hidup eksplan, daya regenerasi tunas, pertambahan tunas per eksplan serta tinggi tunas dilakukan pada subkultur ke tiga, ke enam, dan ke sembilan. Hasil penelitian menunjukkan interaksi genotipe dan jenis eksplan tidak berpengaruh nyata kecuali terhadap daya regenerasi tunas pada subkultur ke enam. Keenam genotipe memiliki tingkat multiplikasi tunas yang berbeda, dan PSJK 922 menghasilkan daya hidup eksplan, daya regenerasi tunas, dan pertambahan tunas terendah pada subkultur ke sembilan. Eksplan dua tunas merupakan jenis eksplan yang optimal untuk multiplikasi tunas in vitro dengan pertambahan 4 tunas per eksplan pada subkultur ke sembilan.Kata kunci: Subkultur berulang, mikropropagasi, eksplan satu tunas, eksplan dua tunas, eksplan tiga tunas

This experiment was arranged in randomized block design, two replications. The objective of this research was to select the promising lines based on crop index and nicotine content. Each lines were morphologically homogen, the potency of yield and quality among lines were significantly different. Foty-four lines were selected. They were resemble to Prancak-95, their nicotine content varied from 1.84% to 4.09%. Genotype and phenotype correlation between nicotine content and yield and grade index were not significantly different. There were 11 selected lines out of the 44 with crop index higher than that of Prancak-95, and their nicotine content vaied from 1.90 -3.96%.

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.
