ABSTRACTThe objective of this research is to improve the chemical properties of peat soil for increasing riceproductivity. The research using factorial randomized block design with 2 factors and 3 replications,consist of a) sea water, and b) mineral materials (zeolite and volcanic material). Mineral materials(M) consist of without mineral materials (M0), 2% zeolite mineral soil samples (200 gram/pot)(M1), volcanic material as much as 10% (1000 gram/pot) (M2), and mixture of zeolite minerals andvolcanic material (M3). Sea water like without sea water (0%) (A0), 25%v/v consentration of seawater (A25), 50% v/v consentration of sea water (A50), and 75%v/v consentration of sea water (A75).The results showed that the application of mineral zeolite and volcanic material significantlyincreased soil pH concentration, P- available, bulk density, dry weight of the canopy and root dryweight. Sea wate significantly decreased pH, cation exchange capacity, shoot and root dry weight,increasing electrical conductivity, base saturation but increasing P- available not significantly onempty grain and weight of 1000 grains.Keywords : sea water, zeolite, volcanic material, peat soil, and paddy

Coffea peel compost and liquid organic fertilizer are potential nutrient sourceto use in organic cultivation of shallot. The growth and production of shallot by giving coffee barkcompost and liquid organic fertilizer. This research was proposed to find out effect of growth andproductions respons of shallot as coffee bark compost and liquid organic fertilizer. The researchstarted from october to december 2011. The design use randomized block design factorial with 2aspect. The first aspect is compost bark coffee consist of four stages those were K0 ( 0 g/plant ), K1( 30 g/plant ), K2 ( 60 g/plant ), ( 90 g/plant ). The second factor is liquid organic fertilizer consistfour stages those are P0 ( 0 ml/l water ), P1 ( 3 ml/l water ), P2 ( 6 ml/ l water ), P3 ( 9 ml/l water ).Coffee bark compost given ferform real effect to number of leave per clumb 6 MST, diameter ofbulk and production per plot but not gave any influenced to high of plant, leaves number per sample2 – 5 MST, number bulbs per sample, wet weight per sample and dry weight per sample.

ABSTRACTThe effect of Vegetative Growth on some Varieties of Black Soybeans with The Provision ofVermicompost on Acid Soils.Insufficient Black soybeans productiondomestic demand is a problemthat faced today. The addition of organic matter and using acid soils is one way that can be done toincrease the production of black soybean.The objective of the research was to know the effect ofvegetativegrowth on some varieties of black soybeans (Glycine max (L.) Merrill) with the provisionof vermicompost on acid soils. The experiment was conducted in the Public Land, Pasar I, TanjungSari, Medan, with altitude ± 25 meters above sea level from July to October 2012.Using a factorialrandomized block design with the first factor application of vermicompost (0, 0.8, 1.6 and 2.4kg/m²) and the second varieties (Detam-1, Detam-2, Cikuray, Merapi, Malikka) with threereplications. The result showed that the application of vermicompost insignificanly affected to all ofparametric in the research. The variety significantly affected the plant height at 2, 3, and 5 MST,andthe number of branches on the main stem. The combine between application of vermicompost andsoybean varieties were insignificanly to all of parametric in the research.Key word : soybean, acid soils, vermicompost, varieties

ABSTRACTThe effect of Concentration and Frequency of Etephon Aplication on Growth and Production ofcucumber (Cucumis sativus L.). Cucumber in Indonesia is popular and likely vegetable for all ofsociety. Cucumber productivity (ton/ha) in Indonesia from 2007 to 2011 were decrease from 81.2 to527.1 this was due to less intensive and efficiency in cucumber culture one of the alternative that couldbe done was application etephon of plant growth regulator. The aim of this research was to know theeffects of concentration and frequency of etephon application on growth and production of cucumber,this study was done in faculty of agriculture net house medan (± 25 in above sea level) from Januari –maret 2013. The design used was Randomised Block Design with 2 factors, etephon concentration (0.150, 300 dan 450 ppm) and the frequency of application (1x, 2x and 3x times). The parameterscolected were plant length, number of leaves formed, number of lived leaves, number of femaleflowers, number of female flowers aborted, number of male flowers, ratio of flowers, number of fruitper plant and total weight perplant. From the research, concentration affect significantly on plantlength (4-8 weeks after planting), number of female flowers (39 and 51 days after planting), number offemale flowers aborted (42 and 60 days after planting), number all of male flowers, ratio of flowers (48days after planting). Frequency aplication of etephon affect significantly plant length (6-7 weeks afterplanting). Interaction affect significantly on flowers ratio (48 days after planting ).Keywords : cucumber, concentration , and frequency Etephon.
