Abstract

High soil acidity is one of the problems causing low hot pepper yield on Acid Sulphate Soils. Using tolerant variety and application of ameliorant were some efforts to increase hot pepper yield on Acid Sulphate Soils. The objective of this research was to study the effect of ameliorant application on the growth and yield of three hot pepper varieties on Acid Sulphate Soils. This research was conducted on Acid Sulphate Soil at Barambai-Barito Kuala District-South Kalimantan on the dry season of 2004. The experiment was arranged in Split-Plot Design with three replications. The main plots were ameliorant application, i.e. control, liming 2 t.ha-1, liming 2 t.ha-1 + manure 5 t.ha-1, and the sub plots were three hot pepper varieties, i.e. Hot Chili, Jatilaba and Tit Super. The result showed that the yield of hot pepper was affected by ameliorant application, varieties and interaction between ameliorant and varieties. Liming increased yield. Hot Chili tolerated high soil acidity and had the highest yield (11.489.7 kg.ha-1) on 2 t.ha-1 liming.   Key words :  Ameliorant, hot pepper, acid sulphate soil

Abstract

The objective of this research was to study the effect of irrigation system on production and organoleptic quality of tobacco. The treatments were conventional irrigation, drip irrigation with mulch and drip irrigation without mulch.  Conventional irrigation was the irrigation system that was usually applied by farmer.  Plastic pipe was used for conveying water from water resource to field, and the irrigation was given twice a week. Drip irrigation was given once in two days. Drip irrigation with mulch resulted higher sun cured leaf weight and water used efficiency than conventional irrigation, but it was not significantly different compared with drip irrigation without mulch.  Drip irrigation without mulch resulted 5.505 ton/ha of sun cured leaf and water use efficiency as much as 3.4 g of sun cured leaf/kg of water.  Organoleptic quality resulted by three irrigation systems were mild to medium, fairly smooth and low irritant.   Key words :  Drip irrigation, mulch, water use efficiency, organoleptic quality, tobacco

Abstract

The development of a suitable technology for handling  sugar cane plantation's solid organic waste especially bagasse, filter mud, and trash is one of the most important concerns in the management system of sugar cane plantation.  Solid organic waste of sugar cane is potentially suitable as a compost raw material processed by introducing lingocellulosic-degrading microbes, particularly Phanerochaete chrysosporium, Trichoderma pseudokoningii, and Trichoderma sp. The microbes were formulated in a commercial bioactivator product namely SuperDec. The significant results have been obtained on biodegradation of trash composted by using this bioactivator.  Compost maturity could be reached in 7-21 days of incubation indicated by the reductions of solid organic waste particle size and C/N ratio. Based on selected production component values of this trial, the production cost of trash-originated compost is Rp. 200,-/kg with nutrient value equivalent to Rp. 260,-/kg.  Combined applications of the compost with NPK single or with NPK compound fertilizers yielded higher biomass production i.e. 28.5 and 13.3%, respectively, than that obtained from standard NPK single fertilizer application.   Key words:   Sugar cane plantation, solid organic waste, SuperDec, composting technology, C/N ratio, production cost

Abstract

Methane (CH4) is an important greenhouse gas that has a high heat trapping capacity thus potentially contribute to the global-warming.  Agriculture is considered among the responsible emission sources of CH4. Relationship among soil characteristics, soil microbes, and CH4 flux is very important in understanding the mechanism involved in the mitigation effects of certain agriculture practices. Results of this research showed that rice field produced the highest CH4 flux (7.4976 ± 0.5299 mg CH4-C m-2 h-1, n=3), while vegetable, sweet potato, yam bean and corn cropping produced lower CH4 flux (-0.7708 ± 0.6434 to 0.4605 ± 0.5255 mg CH4-C m-2 h-1, n=3). Nitrifier population among cropping systems was 3.13x103 to 3.17x104  MPN g-1 soil (dry weight), while denitrifier population was 3.77x103 to 1.17x105 MPN g-1 soil (dry weight).  There were no specific dominance proportion of nitrosomonas, nitrobacter, denitrifier and total propagule among cropping systems. The CH4 flux had highly correlation to soil water content (r = 0.951), soil pH (r = 0.852) and soil Eh (r = -0.982). Denitrifier had significantly correlation to soil pH (r = -0.635) and soil ammonium content (r =  -0.681).   Key words :  CH4 flux, cropping system, soil characteristic, soil microbes

Abstract

The objective of the research was to study the impact of agro-tourism on production of tea bud. The experiment was conducted at Gunung Mas Tea Plantation, Bogor, from June 2004 to March 2005. Blocks 3, 5, 8, 10 and 17 at Gunung Mas I afdeling represented area with agro-tourism activity and blocks 3, 7, and 10 at South Cikopo I afdeling represented area without agro-tourism activity. Site selection was based on plant variety, age of cutting, tea walk track (0, 4, 6, and 10 km), and elevation height (800, 900, and 1000 m above sea level). The result shows that agro-tourism activity decreases production of tea bud. When the number of visitors increased, production of tea bud decreased because the pluckers were absent during the plucking time. The positive impacts of agro-tourism are improvement in plantation management, especially in productive plants, and existing additional income. Gunung Mas Tea Plantation especially Gunung Mas I afdeling which runs agro-tourism should limit the number of visitors and there must be a cross subsidy from agro-tourism to agro-industry sectors.   Key words :  Agro-tourism, productivity of tea shoots, afdeling, plucking.

Abstract

Saturated soil culture (SSC) is a cultivation technology that gives continuous irrigation and maintains water depth constantly and makes soil layer in saturated condition. By keeping the water-table constantly, soybean will be avoided from negative effect of inundation on soybean growth because soybean will acclimatize and improve its growth. The objective of the research was to study the response of soybean varieties under saturated soil culture on tidal swamps. The research was conducted at Banyu Urip of  Tanjung Lago Sub District, Banyuasin District, South Sumatera Province, Indonesia from April to August 2009. The experiment was arranged in a split plot design with three replications. The main plot was water depth in the furrow consisted of without watering, 10, 20, 30, 40 cm under soil surface (uss). The subplot was soybean variety consisted of Tanggamus, Slamet, Willis, and Anjasmoro. The result showed that the interaction between varieties and water depth significantly affected growth and seed production, except pod numbers/plant. The values of all variables were higher under SSC compared to those cultivated without watering (control), but varieties responded to SSC differently. The highest seed production was obtained from Tanggamus with 40 cm uss, i.e. 4.83 ton/ha but it was not significantly different from those at water depth 20 (4.63 ton/ha) and 30 cm uss (4.71 ton/ha). However, technically and economically, 20 cm uss was the most appropriate water depth for soybean production on tidal swamps.   Key words: Glycine max L. (Merr.), water management, water table

Abstract

Preliminary Yield Trials and Grain Quality of 21 Promising Hybrid Rice. Hybrid rice varieties are alternative technology for increasing national rice productivity.  Heterosis effect from the hybrid F1 can increase yield potential 15% more than inbred rice varieties. The objectives of this experiment were to test the yield and rice quality of some hybrid rice varieties, compared with the three check varities i.e. IR64, Memberamo, and Maro. This experiment was conducted at Muara Experimental Farm, Bogor during wet season 2002/2003 (December-May). A Randomized Complete Blocked Design in three replications was used for this experiment. The result shows that the yield of hybrid rice combinations H-27, H-28, H-29, H-30, H-31, H-32, H-35, H-37, H-38, H-39, H-40, H-41, H-42, H-43, H-45, H-47, H-48 had short growth duration and have erect leaf appearance, but most of them had less resistance to pests and diseases caused by bacteria, and low percentage of grain content. The yield of these hybrids except H-27 and H-49 were lower than the check varieties and all of the hybrid rice tested in this experiment were good in terms of cooking quality. H-27, H-30, H-34, H-41, H-45 dan H-49 could be tested in the advance yield trials.   Key words: hybrid rice, preliminary yield, grain quality

Abstract

Aluminum (Al) toxicity is one of the most important yield-limiting factors for upland rice grown on acid soils. Since many small farmers may have difficulty in soil liming, the genotypes tolerant to soil acidity and aluminum toxicity should be developed. Anther culture can substantially speed up new variety development through recombination of parental characters in early generations and immediately homozygous lines were upon chromosome doubling. The Doubled haploid (DH) rice lines were screened under both nutrient solution containing either 0 or 45 ppm Al and acid soils containing either low or high-Al saturation. The relative root length (RRL) was determined at 14-day-old stage to characterize genotypes for Al-tolerance in nutrient solution. The relative grain weight (RGW) was determined to characterize genotypes for Al-tolerance in soils conditions. The results of this study indicated that Al reduced root elongation. The differential tolerance for Al among genotypes was found to be highly significant for RRL. Of the 120 genotypes tested, 16, 77 and 27 genotypes were found to be Al-tolerance, moderate and sensitive in term of RRL respectively. KRGM4, JTGR13, JTGR17, JTGR18, JTKR1, JTKR5, GRGM4, GRGM6, GRGM9, GRGM14, GRGM25, GRJT11 and SGJT27 lines were consitently Al-tolerance under both nutrient solution and acid soils. The RRL of doubled haploid upland rice lines in nutrient solutions were strongly correlated with RGW in acid soils.   Key words: Rice, doubled haploid, aluminum tolerance, relative root length, relative grain weight
