Abstract

Effect of plant spacing on the number of buds of capok clonesThe experiment was conducted at Muktiharjo Experimental Farm. Pati from December 1991 to December 1993. The experiment was arranged factorially in a split plot design with three replications. The main plot was plant spacing, i.e. 2 m x I m and 2 m x 2 m, while the sub plot was clones (source of buds), namely MH I. Mil II. logo B, (lanang 36 x Siam) x Congo, (Congo 2 x Lanang). (SS 29 x Congo), (Jepara x Congo 2), and (P. Gudang x Lanang) x Congo. Plot size was 20 m x 4 m The size of planting hole was 0 6 m x 0 6 m x 0.6 m. one plant per hole. Canle manure mixed with soil was applied at planting lime Results showed that capok with plant spacing of 2 m x I m produced higher number of active buds per ha ( 147 625 buds) than that with plant spacing of 2 m x 2 m (79 661 buds). However, ihe first plant spacing produced smaller diameter (34.47 mm) than the second one (42.53 mm) The highest number of active buds was produced by the clone SS 29 x C, i.e. 123 959.33 buds per ha or 33.33 buds per plant

Abstract

Engineering of solar collector and LPG-burner for curing Virginia tobaccoIndonesia produces 30 tones of Hue cured tobacco every year. Curing Virginia tobacco needs I 29 I kerosene per I kg cured leaves, thus lo process 30 tones cured leaves, it needs 38.7 liter kerosene with a value ol Rp 1 5.5 billion per year Kerosene as a source of energy is used for house hold in Ihe village and it is highly subsidized by the government. For such industries as tobacco processing other sources of energy are available, including gas oil, diesel oil and fuel oil, solar energy, coal, and liquid petroleum gas This study was aimed at designing solar collector and LPG buner suitable lor Virginia tobacco flue curing. Tobacco leaves were cured in a curing barn with LPG as a fuel, while the solar collector was installed on Ihe roof of Ihe barn. The size of the curing barn was 4 m x 4 m x 7 m with a capacity of iwo tones fresh leaves. The LPG-burner used was BA'I'/Baliltas-I, with was specially designed for lobacco curing barn ('nring method followed Ihe standard method practiced by farmers The experiment was conducted al IT Sadhana Arif Nusa. Has! Lombok. NTR from Angus! lo September 1997 The rcsull of experiment was evaluated holh from technical and economical aspects. The used of LPG combined with solar collector as the source of energy could reach Ihe required temperatures (J0-70°(.) during curing phases LPG consumption was 0.86 kg/ kg cured leaves, and solar energy contributed 6.48% of total energy required for curing process From economical view, the used of LPG and solar energy was not profitable. This was mainly due to Ihe high prices of LPG (Rp I 000 /kg) LPG-lank (Rp 1 600 000/unit) and roof- solar collector (Rp I 500 000 per unit).

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

Response of four new coconut hybrids to bud rot and premature nutfull diseasesThe objective of Ihe experiment was to find out Ihe resistance of four new coconut hybrids GRA x DMT. GKB x DMT, GKN x DTE. GKB x DTE against bud rol and premature nutfall diseases due lo Phytophthora palmivora. The field observation on bud rot was conducted in coconut trial plots at Kima Atas experimental garden. Minahasa District, North Sulawesi Province for 4 years (1995-1998). The field trial was arranged in a randomized block design with 6 treatments (4 coconut hybrids. 2 control) and 60 replicates The experiment under laboratory condilion was conducted to know the artificial infection development of P palmivora on coconut nut The experiment was arranged in a completely randomized design with 6 treatments (4 coconut hybrids, 2 control) and 10 replicates. The result of the field observation showed that percentage of coconut infection by bud rot per cultivar were PB-121 (23.33%) as the highest and then followed by GKN x DTE (8.33%), KHINA-1 (5.0%) and GKB x DMT (3.33%) while cultivars of GKB x DTE and GRA x DMT unlil 4 years observation were not infected by bud rot In laboratory trial, Ihe growth rate of pathogen was very high on KHINA-1 (12.62 mm2/day). The growth rate of pathogen in GKB x DIE and GRA x DMT were slowest (8 9 mm'/day) while those in PB- 121, GKN x Dll and GKB x DMT were moderate (9-10.2 mm2/day).

Abstract

Effectiveness of biofertilizer and IS fertilizer (ZA) in increasing the yield and quality of Virginia tobacco leaves, population of soil bacteria and soil /V contentThe experiment was conducted in inceptisol soil, Bondowoso, from June 1998 to March 1999. The experiment was aimed to study the effect of biofertilizer and N rates on population of soil bacteria and total N soil content, yield and quality of Virginia tobacco leaves The experiment was designed in factorial randomized block with two factors and four replicates Factor one consisted of two levels of biofertilizer (0 and I l/ha) and factor two was three levels of N rates (0, 25 and 50 kg N/ha). Biofertilizer was sprayed before planting and N fertilizer was added twice, at 10 and 21 days ater planting, half dosage each PjO^ (40 kg/ha) and K20 (90 kg/ha) were added as basal fertilizer. Biofertilizer (1% product) was sprayed into the plant holes (volume 100 l/ha) prior lo planting of tobacco seedlings. Results showed that interaction between biofertilizer and 2S kg N/ha treatments increased fresh leaves yield by 22% and cured leaves by 30%, and also resulted in a high value of crop index (110.16) Quality index was only increased (5%) by addition of biofertilizer In the laboratory, the combination treatment of biofertilizer and N also increased the population of bacteria and total N content of soil that was incubated for 2 weeks.
