Yellow traps is one of mechanical control leaf miner (Liriomyza spp) on shallolt(Allium ascalonicum (L.). This study was conducted in Desa Batukarng located at the altitude of about1,100 meters above sea level.The purpose of this study was to fine out the influence of the use severalforms and altitude of yellow. Trap on Liriomiza spp ( leaf-slitting fly) as the pest on shallot(Allium ascalonicum (L.). This study employed the Non-Factorilal Group Random Design Methodwith 7 treatments and 3 repetitions by using yellow square and cylindrical trap set at the latitude of10,30,50 cm above the ground. The result of this study showed that the average number of pets trappedhad a significant influence on the population of Liriomyza spp ( leaf-slitting fly) at shallot plantingground of square treatment with height of 10 cm. The form and height of trap had a very significantinfluence on percentage of Liriomyza spp attack to the square treatment with the height of 10 cm.Based on the result of the study, it is found out the square trap with the height of 10 cm is moreeffective to control the population of Liriomyza spp.Key words: shallot , leaf- slitting, yellow trap.

Soybean production is influenced by the variety and nutrients available in the soiland plant roots can absorb. This research means to test the response of severalvarieties of soybean (Glycine max L.Merill) for guano fertilizer. Location of theresearch was conducted in the Tanjung Selamat village, Deli Serdang regency,using a randomized block design of two factors they are varieties (Anjasmoro,Burangrang and Argomulyo ) and guano doses (250, 300, 350, 400 and 450kg/ha). The parameters observed were plant height, branch number produtive,number of pods per sample, the number of filled pods per sample,number ofempty pods per sample, weight of dry seed per sample, weight of dry seed perplot, weight of 100. The results showed that varietie significantly influenced toplant height, branch number produtive, number of pods per sample, the number offilled pods per sample,number of empty pods per sample, weight of dry seed persample, weight of dry seed per plot, weight of 100. Varieties and fertilizertreatment interaction effect was not apparent guano on all parameters.Key word : soybean, variety, guano

Vegetative and Generative Characters of Aluminium Sensitive Rice Varieties. Aluminium (Al)tolerant mechanism in rice has not been fully understood. The objective of this research was tostudy the vegetative and generative characters of Al sensitive rice varieties. Five days old of riceseedlings were growned on minimum culture solution containing 15 ppm of Al for 72 hours andthen transferred to non Al-treated culture solution for 48 hours. The selected seedlings wasmeasured based on RRG value. RRG value was determined based on after Al-stress. This researchwas held at Greenhouse in Faculty of Agriculture, University of North Sumatera Utara, Medan,from May until October 2012, using latin square Design with treatment that was rice varieties:Inpari 3, Inpari 4, Inpari 10, Inpari 12 and Inpari 13. Data analysis showed that varieties with Altreatedwere significantly different the vegetative stage, the flower initation, the time of harvestingand the generative stage time. Varieties were not significantly different the plant height, the numberof tillers, the number of productive tiller, the panicle length, the flag leaf length, the number ofpanicle branches, the number of empty grain per panicle, the grain weight per panicle and the 1000grain weight.Keywords : Varieties, Al Sensitive, Root Re-Growth, Vegetative Characters, Generative Characters
