Production Growth response and mustard (Brassica sinensis L,.) By Giving Mineral Zeoliteand Nitrogen, guided by Jasmani Ginting dan Ferry Ezra Sitepu. This study aims to test theresponse of the growth and production of mustard on the provision of zeolite and ureafertilizer. The study was conducted in community land Setia Budi Road Simpang SelayangMedan district in May to July 2012. Experimental method used was a factorial randomizedblock design with 2 factors, namely the provision of zeolite (0 g, 50 g / plot, 100 g / plot, 150g / plot) and urea fertilizer (without urea, 0.2 g / tan. , 0.4 g / tan., 0.6 g / plant) with 3replications. The parameters measured were plant height, leaf area, leaf chlorophyll amount,weight biomass per plant, fresh weight per plant and sell the sample harvest index. The resultsshowed that administration of zeolite significant effect on all parameters. While the treatmentof urea fertilizer and the interaction between the two treatments did not significantly affect allparameters.Keywords: zeolite, urea, growth and production of mustard.

The research was conducted to examine P-available of paddy soil potential of acid sulfate withBray II, Truog and Olsen. The research held in Seed Technology Laboratory (seeding), green houseand also in Research and Technology Laboratory Agriculture Faculty University of SumateraUtara. The research used non factorial Randomized Block Design with 3 repetition, which as mainfactor is the giving of Natural Phosphate with 9 kind of dosages, that is: 0, 50, 100, 150, 200, 250,300, 350, and 400 ppm. The giving of Natural Phosphate was significant to the phosphorus sorptionwith the best dosage is P7 (350 ppm) and pH with the best dosage is P8 (400 ppm). The examiningof P-available from the giving of natural phosphate results that the value of P-available by usingBray II and Truog method was higher than the value of P-available by using Olsen method, andthere is no appropriate value of P critical limit for each method.Keywords: P-Available, acid sulfate soil, potential

This research aims to find out the influence of application organic matter and rock phosphate toimprove soil chemical characteristic, growth and production of rice plant in acid sulphate soils, it isrelated to acid sulphate soils case, such as low pH, high iron (Fe2+) making less production. It isconducted in Faculty of Agriculturegreenhouses, University of North Sumatra, using a randomizedblock design factorial, with 2 factors; organic matter (B), B0 =(0 g /pot); B1 = (40 g straw /pot); B2= (80 g straw/pot); B3 = (40 g cow’s manure/pot); B4 = (80 g cow’s manure/pot); B5 = (26,7 gstraw + 53,3 g cow’s manure/pot) and rock phosphate (P), P0 = (0 g /pot); P1 = (0,64 g rockphosphate /pot); P2 = (1,28 g rock phosphate /pot). The measured parameters were pH, C-organic,P-avaliable, Fe2+, plant height, maximum seedlings and weight of dried grains. The results showedthat organic matter application significantly affected in increasing pH, P-avaliable,maximumseedlings, plant height, weight of dried grains and decreasing Fe2+at final vegetative phase. Rockphosphate application significantly affected in increasing pH, P-avaliable, weight of dried grainsand decreasing Fe2+at final vegetative phase. Combination of the two factors significantly affectedin increasing pH, P-avaliable, maximum seedlings, plant height, weight of dried grains anddecreasing Fe2+at final vegetative phase.Key words: acid sulphate soils, rice plant, organic matter, rock phosphate

At the market, composts are sold varied in their quality. Some of them are originated fromforest floor and other are collected from burnt and half- decomposed municipal waste. Thereis no control for commercial compost by government, thus many of composts sell at marketare not registered. Buyers should able to detect the good and bad compost quality in thesimple ways. This present experiment was conduct to develop a new simple visual test todetect the good and bad compost quality and comparing test result with the test result oflaboratory analysis and field experiment. The composts used in this experiment were:vermicompost (made by researcher), 2 burnt municipal waste (burned by researcher) and 8commercial composts. Simple test consist of several parameters viz color, odor, react ofcompost when put into water, The compost laboratory analysis were: pH, carbon organic,total nitrogen, ratio, C/N, total microorganism number, water holding capacity, compostparticle size composition. The field experiment test was conducted in the screen house usingmustard as an indicator plant. The experiment design was randomized block with 12treatments (vermicompost as a control for good compost, 2 burnt municipal waste compostsas a control for bad compost, 8 commercial composts and without adding compost) and 3replications. The result showed that the color of burnt municipal waste composts weregrayish, while the color of vermicompost was dark brown. No Odor of burnt municipalwaste compost was founds, while the odor of vermicompost was humid odor. All of theburnt municipal waste composts were sinking into the bottom of glass when it puted intowater, and not for vermicompost. Almost all of compost solid from forest floor was floatingwhen puted into water. The laboratory analysis test showed the burnt municipal compostshad the lowest C organic, N total content, C/N, and total microorganism number, and had thehighest pH value compare to other composts. The tests showed that some of commercialcomposts quality were bad. Meanwhile, the result of field experiment test did not gave thesignificant effect on the growth and production of mustard (Brassica juncea) using good orbad compost quality compare to control (without adding compost). As conclusion, the badquality of compost especially the burnt municipal waste compost, and the forest floorcompost were able detect using simple test by putting it into water.Keywords : vermicompost, burnt municipal waste, commercial compost, simple test,laboratory test, field experiment test

The objectives of this research was to study effect of aplication empty fruit bunches oil palm andconcentrated flow areas depth treatment on N, P leaf nutrient content and production. The researchwas conducted in Afdeling II, at block F17, PTPN III Kebun Bangun, Simalungun, NorthSumatera, from July to October 2013, used factorial randomized block design with two factors and3 replication. The first factor was aplication empty fruit bunches oil palm were 0, 200 kg, 250 kg,300 kg. The second factor was concentrated flow areas depth were 40 cm, 60 cm, 80 cm. The resultof this research showed that aplication empty fruit bunches oil palm increase P leaves content butnot significant effect N leave content, and production. Concentrated flow areas depth treatment hasnot significant effect N, P leaves content and production. Interaction of EFBOP treatment andconcentrated flow areas depth increase P leaves content but not significant effect on N leavescontent and production.Keywords: EFBOP, concentrated flow areas, N leaves content, P leaves content, oil palm

This researchaims to select the soybeans that can grow well and good production on saline soil of F4 generation.This research was conducted at Tanjung Rejo village,subdistrict of Percut Sei Tuan, Regenecy ofDeli Serdang,the elevation is 1.5m on above sea level,since November 2012 up to January 2013.The analysis used in this research is fingerprint analysis of cross that consist of 1 variety, themethod applied is a F4 generation pedigree selection,the population is sample, number of live plantis 43 of 690. The selected plant is based on the grain production per plant for 30 plants.Based on theresults of research that based on the highest weight of seed per plant is 1.4g on the plant number514.1.8.6 and the lowest production is 0.1g on the plant number 88.5.10.2, 1298.5.3.1, 1298.5.3.30,1298.5.3.40, 1298.5.7.16 and 1298.5.7.25. The components of production that has a direct influenceto the grain production per plant are the number of branch,age of flowering,number of pod andnumber of pods contain. Component of production that giving the highest direct influence is thenumber of pod contain for 8.809.Keyword : Species, Soybean, Selection, Salinity.
