The purpose of the study was to determine the growth response of oil palm seed on waste market compost and Npkmg (15:15:6:4) fertilize aplication in pre nursery. The research was conducted atthe experimental field Agricultural Faculty, Sumatera Utara University about ± 25 metres above sealevel from April to July 2014. The design use randomized block design with 2 factors treatment.The first factor was The waste market compost with 4 levels: 0 g/polybag (K);50 g/polybag (K1); 100 g/polybag (K2); 150 g/polybag (K) and the second factor was NPKMg (15:15:6:4)fertilizer with 4 levels: 0 g/polybag (P03); 2,5 g/polybag (P1); 5 g/polybag (P) and 7,5g/polybag(P32). The results showed that the waste market compost treatment has significantly effectto the plant height, total wide leaf, dry weight root and soil pH , however no significantly affectedfor, stem diameter, leaf number, length of the root, fresh weight of crown, dry weight of crown, andfresh weight of root. The NPKMg (15:15:6:4) fertilize treatment showed significant effect to stemdiameter, total wide leaf, fresh weight of crown and dry weight of crown however no significantlyaffected for plant height, leaf number, lenght of the root, fresh weight of root, dry weight of rootand soil pH. The interaction of both of treatmet showed significan for the plant height and totalwide leaf. Keywords: Oil palm, waste market compost, NPKMg (15:15:6:4) fertilizers. 0

The objective of the research was obtained the appropriate of media composition and soakingperiod of auxin toward growth of bud chip technique sugarcane seedling. The research wasconducted at experimental field of Tanjung Jatti Estate Binjai PTPN II (± 50 m asl.) in April – Juny2014 using a randomized block design with two factors. The first factor was media compositionwith levels: 50:50, 70:30, and 30:70 (% top soil: % blotong compost), and the second factor wassoaking period of auxin with levels: 10, 20, and 30 minutes to consentration 2 ml/L with threereplications. The result of this research showed that application of media composition wassignificant effected on seedling growth percentage at 1 week after planting (WAP), plant height andstem diameter at 6 WAP, leaf total at 4 and 6 WAP, leaf area at 8 WAP, sturdiness value, shoot/rootratio and seedling quality index. The soaking period of auxin was significant effected on leaf area at 8 WAP and shoot/root ratio. Interaction of both was significant effected only on leaf total at 2 WAPwith M1T3 was the highest. Keywords: bud chip, media, auxin, sugarcane

The growth of seedlings in the field in very determined by the growth of plants in the nursery.Planting media is the one factors that affect the growth of plants in the nursery. Therefore, by givingmikorizha and composition of the planting media is expected can increase the growth of oil palmnurseries in pre nursery. This research was conducted in screen house af Faculty AgriculturalUniversity of Sumatera Utara with altitude ± 25 meters from sea surface from April-July 2014, usedrandomized block design with two factors. The first factor is composition of planting media (sludge+ ultisol) with four levels (0% + 100%) (S0); (25% +75%) (S1); (50% + 50%) (S); (75% + 25%)(S3) and the second factor is mikorizha with three levels 0 (M0); 5 (M12); 10 g/plant (M). Parameterobserved was plant height, stem diameter, number of leaves, total leaf area, leaf greenes, degree ofinfection, root volume, shoof dry weight root dry weight. The result of this research showed that useof planting media composition significantly effect to plant height parameters 6-12 weeks afterplanting, stem diameter 6-12 weeks after planting, number of leaves 6,7,8,10,11 weeks afterplanting, total leaf area, green leaf, degree of infection, root volume and plant dry weight.Mikorizha treatmen is significantly effect the degree of infection parameters. Interaction ofcompositition planting media and mikorizha significantly effect on plant height at 6 weeks afterplanting and degree infection.Keywords: mikorizha, sludge, ultisol, palm oil 2

Palm oil is one of the major and prime agricultural commodities in Indonesia. Better palm oilseedling growth depend on nutrient and organic matter availability that can be fullfilled by usingpalm oil mill effluent (POME) and NPKMg (15:15:6:4) fertilizer. The objectives of the researchwere to study growth response of palm oil pre nursery seedling to aplication of POME and NPKMg(15:15:6:4) fertilizer. The research was held at screen house of Agricultural Faculty USU (±25 m asl) in April to July 2014 using a factorial randomized block design with two factors and threereplications. The first factor were POME (0; 1.5; 3.0; 4.5 l/seedling) and the second factor wereNPKMg (15: 15: 6: 4) fertilizer (0; 2.5; 5.0; 7.5 g/seedling). Data were analyzed with ANOVA andcontinued with Duncan multiple range test. The Parameters observed were plant height, stemdiameter, leaves number, total leaf area, leaves greenness, fresh and dry root and upper part weight.The results obtain were the effect of POME until dose L (3.0 l/seedling) were increase for allparameters except leaves greenness, fresh and dry root. The effect of NPKMg (15:15:6:4) fertilizeruntil dose P22 (5.0 g/seedling) increase for all parameters except stem diameter. The interaction ofthese two factors until L3Pwere increase leaves number, leaves greenness, fresh root weight, freshand dry upper part weight.Keywords: palm oil mill effluent, NPKMg (15:15:6:4) fertilizer, palm oil seedling 3

This research aims for knowing the response a giving of oil palm seeds in the results of giving empty fruit bunches of oil palm compost and zeolite in pre nursery. The researched was carried outat Faculty of Agricultural screen house, USU (± 25 mdpl) in March – July 2014 using a randomizedblock design with two factors. The first factors was dose empty fruit brunches of oil palm compostwith four levels that were including 0 g/polybag; 15 g/polybag; 30 g/polybag; 45 g/polybag; andthe second factor was dose of zeolite with four levels that were including 0 g/polybag; 5 g/polybag;10 g/polybag; 15 g/polybag. The results of research shows that the application of empty fruitbrunches of oil palm compost had a real impact on the stem diameter and total leaf area. As for thediameter of stem best level was obtained at treatment EFBOP compost 45 g/polybag and total leafbest level was obtained at treatment EFBOP compost 30 g/polybag. Giving the zeolite wasevidently influencial toward the stem diameter, total leaf area, crowns wetness weight, root drynessweight, and crowns dryness weight. Zeolite best level was obtained at treatment zeolite 5g/polybag. The interaction between empty fruit brunches of oil palm compost and zeolite fertilizerwas evidently influencial towards the total leaf area and crowns dryness weight in pre nursery. Besttreatment combination level was found of which was 30 g/polybag of empty fruit brunches of oilpalm compost and5 g/polybag of zeolite. Key words: EFBOP compost, zeolite, and oil palm

The aim of the research was to identify growth characters of shallot var. local samosir with gammarays irradiation. Research was conducted at the Jl. Selamet Ketaren, Medan with a height of 25meter above sea level began from April until July 2014. Bulbs of shallot were exposed to severaldoses (0, 1, 2, 3, 4, 5, and 6 Gy) using Co60 source. Differencies of growth characters (shoot length,leaf number and tiller number per clump, harvest time, fresh and dry weight of bulb per plant, bulbdiameter and average weight per bulb) was analyze by t test using minitab v.16. The results showedshoot length 6 weeks after planting (WAP) were shorter 1.97cm, 2.38cm, 3.1cm, 4.73cm and4.49cm at doses 2,3,4,5,6 Gy; leaf number 2 WAP were reduced 35.16% and 39.24% at dose 5 and6 Gy, meanwhile tiller number 6 WAP was increased 13.88% at dose 6 Gy respectively comparedto control. Fresh weight and dry weight of bulb were lighter 30,39% and 37,04% at doses 5 Gy and38,52% and 47,44% at doses 6 Gy; average weight per bulb were lighter 23,2%, 47,64% and47,98% and bulb diameter were smaller 11,48%, 25,48% and 30,41% at doses 4,5,6 Gy respectivelycompared to control.Key words : Shallot var samosir, gamma rays irradiation, doses
