Abstract

The contribution of estate subsector to the income of the farmers living in the forest and in the ■urronding area is still low. This study was caried out socioeconomic and their roles in improving their welfare. The study was conducted rom August to October 2000 in three forest management systems (1) system of Hak Pengusahaan Hutan (HPH) which was represented by Sukamulya and Siabu villages, Bangkinang, Kampar District, and Rambah Jaya Village, Rambah Hilir, Rokan Hulu District; (2) System of Hutan Taman Nasional which was represented by Andongrejo and Eaat Java Province; (3) System of Hutan Sosial (Perum Perhutani) which waa represented by Kedung Urang Village, Cilacap Subdistrict, and Sawangan Village, Jeruk Legi Subdistrict, Cilacap District, Central Java Province. Sample villages were chosen through purpose sampling method. The data were analyzed desciptively and comparative and approacted through socioeconomic indicators and criteria. The results of the research indicated that the socioeconomic condition of the estate farmers living in the forest and in the surrounding are was lower compared to those of the area was lower compared to those of the rice farmers and others farmers. The average income of the estate farmers ranged between Rp 360 860.00 and Rp 523 550.00. The range of income distribution (Gini ratio) was 0.295 to 0.430. Out of the three forest mana¬ gement systems, the village of Hutan Taman Nasional was better than those of two other systems, where the income level waa Rp 432 000.00 Gini ratio was 0.320; structure and inrastucture was moderate.

Abstract

Arrowroot (Maranta arundinacea L.) is usually propagated through young tillers or rhizome cuttings. A glass house and field tials were carried out at the Cimanggu Expeimental Insulation of the Research Institute for Spice and Medicinal Crops (RISMC), to assess 0k efect of rhizome patition and number of nodes of each parts on the viability of rhizomes, growth, productivity and starch content of arrowroot A clone of arrowroot (No. 17) collected from RISMC was used. One, two, three or four nodes of rhizomes cut at the base, middle or tip were used. A preliminary study was conducted in glass house from August to September 1999, where 40 samples of rhizomes were tested for their viability. Further study was conducted in the field from October 1999 to April 2000, to assess the growth, productivity and starch content of the rhizome from each treatment. The ield experiment was designed as a randomized block, arranged factorially in three replicates. The first factor was rhizome part (base, middle or tip) snd the second one was number of nodes (one, two, three or four nodes). Results showed that the highest percentage of plant growth, and seedling vigor of one month old were obtained from Uic four nodes tip rhizome cutting. At 6.5 month after planting the highest significant yield of resh rhizome was obtained from both base and middle parts rhizome cutting (324.04 and 326.46 g/hill), while the tip curling only produced 240.0 g/hill. The highest starch yield was obtained from the treatments of both the base and middle parts rhizome cutting i.e. 52.51 and 61.25 g/hill, while the tip cutting produced 47.19 g/hill. There was no interaction efect between the irst and the second factors on fresh rhizome yield. Highest signiicant fresh rhizome yield can also be obtained by using more than one node (320.96 - 337.69 g/hill), while a node cuting gave 198.65 g/hill only. Using base and middle rhizome cutting with 3 nodes gave the effective and eficient result, since it gave higher yield of the resh rhizome starch (70.38 and 72.41 g/hill).

Abstract

Effect of organic (biogrcen) and inorganic fetilizers (ammonium sulphate and SP36) on the yield and quality of the temanggung tobacco in andosol soil was studied at Galapansari - Temanggung, from Februai to December 2001. The organic and inorganic fetilizers were formulated in 10 packages, namely : (1) 570 kg ammonium sulphate (AS) ♦ 100 kg SP36; (2) the recommended rate for temanggung tobacco (20 000 kg stable manure 500 kg AS + 100 kg SP36; (3) 5 000 kg organic fetilizer (OF); (4) 7 500 kg OF; (5) 8 500 kg OF; (6) 10 000 kg OF; (7) 12 500 kg OF; (8) 14 500 kg OF; (9) 7 500 kg OF + 3 500 kg sUble manure (SM); (10) 7 500 kg OF + 4 500 kg SM. All the rates of fetilizers were based on one hectare planted area (16 500 plants) The expeiment was designed as a randomized block in four replicates. Results showed that organic fertilizer waa more effective than stable manure in improving die growth, yield and quality of temanggung tobacco. A the rate of 5 000 kg was sufficient to produce high ( 6 313 kg fresh or 800 kg sliced died leaves), grade index (51.68) and crop index (55.31).

Abstract

The cause of stunting disease of black pepper (Piper nigrum) in Indonesia has not yet been confirmed cither due o a virus or mycoplaam. However, similar disease found on black pepper plants in the Southeast Asia is caused by Piper yellow mottle virus (PYMV) which is transmitted by Planococcus citri. This expeiments was aimed o examine the cause of the stunting disease and its insect vectors. The expeiment were conducted from October 1998 to May 2001. Diseased vegetative materials of black pepper plants showing stunting disease were collected from Sukamulya, Sukabumi. The potential insect vectors were collected from black pepper plants in Bogor, IP Sukamulya (Sukabumi), Lampung and Bangka. The insects were fed on the diseased plants obtained from Lampung, Bogor and IP Sukamulya, then transferred o the healthy plants. The healthy plants were produced rom true seeds and cutings oiginated rom Bogor and IP Sukamulya. The tested plants were incubated at the green house and examined for disease development. Diseased leaf samples collected rom black pepper plant rom IP. Sukamulya and the transmitted plants were sent to the University of Minnesota, USA for Ihe virus (PYMV) by using ISEM (immunosorbent electron microscope). The result snowed that the leaves samples rom IP. Sukamulya were infected by PYMV. The morphology and size of the virus were similar to those caused stunting disease in the South East Asia. Potential insects vectors found on the diseased black pepper plants were two mealybugs, P. minor and Ferrisia virgata (Hemiptera; Coccoidca: PaaidbcoccidaeX aa well as an aphid Toxoptera aurantii (Hemiptera: Aphidoidea: Aphididae). The first tial on disease transmission by using P. minor, previously reared on the potato tubers, showed one out of ten tested plants produced disease sympom. The subsequent trial using P minor, bred on healthy black pepper seedlings, showed thee out often tested plants developed disease symptoms. None of the aphid transmitted plants developed Ihe disease. This study confirmed thai PYMV b the cause of stunting disease on black pepper in IP Sukamulya and Lampung and P. minor as the insect vecor of the disease.

Abstract

This expeiment was caried out at Palalang Village, Sub Pakong Distict, Pamekasan District, rom April to October 2000. There were 137 treatments, consisted of 100 FS lines [number 1 to 50 were progeny of Prancak-95 x IW (oriental), number 51 to 100 were progeny of Prancak-95 x IS (oiental)], 36 lines were selected from local cultivar, and Prancak-95 as a check variety. 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

Four hybrids resulted from the first generation of the crossing of madura and oiental tobaccos and Prancak-95 aa a standard vaiety were tested at several locations from 1997 to 2000 randomized block design. The experiments aimed at obtaining promising hybid varieties of the madura tobacco. The yield potency, quality and stability of the hybrids were tested by using the method of yau and HAMBLIN (1994), which was based on lite highest average and the loweat standard deviation. Two promising hybrids, i.e. PIS and PXA had quality and crop indexes higher and had lower content of nicotine compared to that of Prancak 95, and they were more adaptive compared with Prancak-95. The quality indexes of PIS, PXA and Prancak-95 were respectively 79.30 ; 75.65 and 65.02.
