The objective of the research was to study to determine the effect of arbuscular mychorrhizal fungi(AMF). This research conducted at society field Setiabudi, Medan Tuntungan, in May-July2013using factorial randomized block design with two factor. The first factor wasaplication of AMF (0,20, 40, g/plant). The second factor was aplication of rock phosphate fertilizer (0, 50, 100, 150kg/ha). Variable observed consistedinfection degree of AMF,shoot dry weight,root dry weight andweight of dry seeds.The result showed that AMFeffect significantlyinfection degree of AMF, shootdry weight, root dry weight. Dose of rock phosphate fertilizer affect significantly,infection degreeof AMF, and weight of dry seeds. There is not significantly interaction between AMF and rockphosphate fertilizer for all variable observed.Based on the research results of the AMF dose(20g/plant) and rock phosphate fertilizer (150 kg/ha) can increase on soybean growth and production.Keywords: arbuscular mychorrhizal fungi,rock phosphate fertilizer, soybean

Tempe industry liquid waste contains several nutrients that can be absorbed by plant roots.Application of mycorrhiza with tempe industry liquid waste to maize simultaneously planted onInceptisol is expected to increase nitrogen and phosphate available. The aim of this study was toexamine the best concentration of tempe industry liquid waste and mycorrhiza dosage in increasingN and P availability in Inceptisol soil and maize producion. The experiment was conducted in theexperimental fields of the Faculty of Agriculture USU ( ± 25 m asl) from March - July 2013 andusing a randomized block design (RBD) with 2 factors and 3 replications. The first factor wasconcentration of liquid tempe industry waste (0, 20, 40 and 60 mL of tempe industry liquid wastetempe/100 mL of water) and the second factor was mycorrhiza dosage (0, 10 and 20gmycorrhiza/plant). The results showed that the tempe industry liquid waste increased the root dryweight of maize significantly. Application mycorrhiza affected the concentration of N on leafsignificantly. The tempe industry liquid waste and mycorrhiza and its interaction were notsignificant effect on the parameters of the soil pH, C-organic, total-N soil, uptake of N, P-available,the concentration of P on leaf, uptake of P, population of microorganisms,degree of mycorrhizainfection, canopy dry weight of maize, weight of cobs, plant height and stem diameter. The bestconcentration of tempe industry liquid waste was 60% which increased the cob weight of themaize 1.15 to 1.25 times higher than the weight of cobs on the others concentration of tempeindustry liquid waste or without application of tempe industry liquid waste.Keywords : tempe industry liquid waste, mycorrhiza, the availability of N , the availability of P, theproduction of corn .

Generally, propagation of shallot used bulbs as planting material. Cutting bulbs is one way todecrease the use of planting material. Cutting bulbs cause decreasing of growth point per plant. Bymore small plant spacing can balance growth point decreased, so that it can reach optimalproduction. This research was conducted at Jl. Pasar I No. 89 Tanjung Sari, Medan in Mei-August2013, using factorial randomized block design with two factor, i.e; cutting bulbs (no cutting bulbs,cutting 2 section, cutting 4 section) and plant spacing (10x15, 15x15 and 20x15 cm). Parameterobserved were plant height, number of leaves per plant, number of tillers per plant and dry bulbweight per plot. The result of the research showed that no cutting bulbs significantly increased onplant height, number of leaves per plant, number of tillers per plant and dry bulb weight per plotwhich is higher than the other treatments. 10x15 cm plant spacing significantly increased on drybulb weight per plot which is higher than the other treatments. Interaction between two factor notsignificantly effected on all parameter observed.Key words: cutting bulbs, plant spacing, shallot

The research was conducted at Screen house Experiment Berastagi at ± 1340 m asl from April untilJuly 2013 using split plot design with main plot, i.e. organic liquid fertilizer concentration (0, 2, 4,and 6 mL/L) and sub plot is tuber weight difference (≤ 3, 3-6, 6-9 and 9-12 g). Parameter observedwere plant height, duration of green leaves, tuber weight per plant, weight tuber per plot, and tubergrade percentage.The result showed organic liquid fertilizer treatment significantly defend thechlorophyll leaves (duration of green leaves). Tuber weight difference treatment significantlyincrease plant height, main stem number, tuber number per plant, weight tuber per plot and tubergrade percentage on 10,1 – 20 g. The interaction of two factor significantly increase tuber gradepercentage on ≤ 5 g. The best result was showed by organic liquid fertilizer concentration 6 mL/Land tuber weight 9-12 g.________________________________________________________________________________Keywords : weight tuber, organic liquid fertilizer, potatoes tuber

This research aims to obtain the best fruit ripeness, seed drying and the effect of removal ofsarcotesta on germination of papaya seed, variety Callina. This experiment was conducted in theSeed Technology Laboratory, Agriculture Faculty, University of Sumatera Utara during July-September 2013, A factorial randomized block design with 3 factors and 3 replications was used.The factors were fruit ripening (0, 2, 4 days), seed drying (0, 1, 2) days and removal of sarcotesta.Variables observed were germination rate (%/etmal), total germination (%), normal seedlingpercentage (%), seedling fresh weight (g), height of sprout (cm), and peak value of germination(%/day). The results showed that ripening increased rate of germination, total germination, normalseedling percentage, seedling fresh weight and peak value. Interaction between ripening and seeddrying increased height of sprout. The highest germination was obtained for treatments of withoutfruit ripening, without seed drying, and without sarcotesta.Keywords : papaya, ripening, seed drying, sarcotesta.

One of the determining factors of water supply for oil palm which does not use irigation system israin fall. Water supply is the main factor that cope production rate of oil palm. Water supply for oilpalm in field is obtained from rain fall. This research is done in PT.PP London Sumatra Indonesia,Tbk Begerpang Estate plantations, North Sumatera Province, Medan from June to September 2013.This research used secondary data available in company administration. Secondary data for analysisneed consists of component production data as total bunches, average bunches weight, total ofproductive trees, loose fruit weight; production of fresh fruit bunch (FFB); rain fall data and rainday monthly in 2008, 2009 and 2010 on 6 divisions. Analysis method used is double linierregression and correlation analysis. Model tested by classic asumption consists of normality test,heteroskedasticity test, multicollinearity, and autocorellations test by using statistic softwareSPSS.v.17 for windows. The regression analysis shows that rain fall and rain day variables havesignificant influence with alpha 5% (Sig < α 0,05) in FFB production aged 5 years. F-value is5,235 with significant level 0,031. Coeffisien determination obtained is 53,8%. It means 53,8%variance of FFB production can be explained by variables used in this research and the rest 46,2% isexplained by other variables which are excluded. Linier regression model on 5 years is Y = 145,982+ 1,451 rain fall – 27,005 rain day + E. Corelation result on 5, 10 and 15 years with two-tailedanalysis with significant level 1% shows that rain fall and rain day have tight, significant, and samedirection relationship. Corelation value of rain fall and rain day are 0,892; 0,887; and 0,855 eachwith significant level 0,000 (Sig < α 0,01).Keywords: rain fall, rain day, FFB production.
