The Growth and Production of Upland Rice Varieties Situ Bagendit In Different Planting Distance and Giving Straw Compost. The aimed of this research to study the growth and production of upland rice varieties Situ Bagendit in different spacing and giving of straw compost. The research was conducted in the field UPT BBI, Tanjung Selamat at an altitude ± 57 meters above sea level since March 2012 until July 2012 using Randomized Block Design (RBD) factorial with two factors, which are the spacing (20 x 20 cm, 20 x 25 cm , 20 x 30 cm) and straw compost (0, 25, 50, 75, 100 g / planting hole). The parameters measured were plant height, number of tillers, straw dry weight, root dry weight, number of panicle, percentage of empty grain, the amount of grain productive, productive grain weight, grain 1000 grain weight, and grain production per plot. The results showed that the treatment of different spacing significantly affect the number of tillers 4-8 weeks after planting and root dry weight. Straw compost treatment significantly affect the number of tillers 4 weeks after planting, the percentage of empty grain and grain production per plot. The interaction between the different spacing and giving straw compost significantly affect grain production per plot. Keywords : upland rice varieties situ bagendit, distance different plant, compost straw

Study of the Growth and Production of Upland Rice of Situ Bagendit Variety In Sludge Aplicationand Number of seedlings per hill, supervised by Ir. Jonatan Ginting, M.S. andIr. Hj. Sabar Ginting, M.S. The research used Randomized Block Design (RBD) factorial with2 factors, which are sludge (0, 30, 60, 90 g/hill) and number of seedlings (2, 4, 6, 8 seeds/hill). Theparameters measured were plant height, number of tillers, straw dry weight, root dry weight,number of panicle, percentage of empty grain, the amount of grain productive, productive grainweight, grain 1000 grain weight, and grain production per plot. The results showed that the sludgeaplication significantly affected plant height at 2 and 10 weeks after planting, the number of tillers4-10 weeks after planting, root dry weight, the amount of grain productive, and productive grainweight. Number of seedlings per hill significantly affected plant height at 2 and 10 weeks afterplanting, the number of tillers 4-10 weeks after planting, and root dry weight. The interactionbetween the sludge aplication and number of seedlings per hill significantly affected plant height at2 and 10 weeks after planting and root dry weight.

Coconut water is good in increasing the plant’s growth because it containsfitohormon and several growth vitamins. The right dosage of NPKMg fertilizationcan maximize the growth of cacao seedling. This research was conducted in desaTanjung Selamat kecamatan Medan Sunggal, start on January 2012 and end onMay 2012. The design used was a factorial randomized block design with twotreatment factors. The first factor is the duration of soaking in coconut water in 4stages, which are K0 (0 hour), K1 (6 hours), K2 (12 hours), dan K3 (18 hours).The second factor are the application of NPKMg fertilizer (15:15:6:4) in 4 stages:which are: P0 (0 g), P1 (7 g), P2 (14 g), P3 (21 g). The soaking of cocoa seeds incoconut water has significant effect on plant height and number of leaves.Interaction between soaking of cocoa seeds in coconut water and NPKMgfertilizer application has no significant effect on all parameters.Key words : coconut water, NPKMg fertilizer, cocoa, growth and production

The growth of oil palm seedlings (Elaeis guineensis Jacq.) by the application of rice husk andfrequency of watering in the main nursery. This research aims to study aimed to determine thegrowth of oil palm seedlings to rice husk and watering frequency on the main nursery. This researchwas conducted in Greenhouses in the Faculty of Agriculture, University of North Sumatera, Medanwith ± 25 m altitude above sea level in January 2013 to April 2013 using a factorial randomizedblock design with two factors: Media planting rice husk (0:0, 2: 1, 1:1, 1:2) and watering frequency(1, 2, 3 days) parameters measured were plant height, stem diameter, number of leaves, total leafarea, fresh weight of seedlings, seedling dry weight. The results showed that treatment of rice huskgrowing media influence is not obvious to all treatment parameters. Watering frequency treatmentssignificantly affected stem diameter parameter 2 and 6 MST with the highest yield obtained in thetreatment of the frequency of watering every other day. Both treatment interaction effect was notsignificant on all treatments.Keywords: palm oil, rice husk, watering

The availability of top soil as an oil palm sead plant media is very limited, so to contend it is usedsub soil plant media which more available and easier to get it, but it has bad chemicalcharacteristics. Application Oil Palm Empty Bunch (OPEB) compost or Palm Oil Liquid Waste ofaerobic pond is expected to bost growth of Palm Seed (Elaeis guineensis Jacq.).This research hadbeen conducted at Net House of Agriculture Faculty, North Sumatera University in October 2013until January 2014,, using factorial randomized block design with two factor i.e. composition ofplanting media (90% Sub-soil + 10% OPEB compost, 80% Sub-soil + 20% OPEB compost, 70%Sub-soil + 30% OPEB compost, and 100% Top-soil) and Palm Oil Liquid Waste (0, 1, 2, and 3litre/plant).Parameter observed were plant’s height, stem diameter, number of leaf, total leaf area,volume of root, upper part fresh weight, root weight, upper part dry weight, dry root weight. Theresult showed composition of planting media on palm seed give no real effect to all of parameterobserved.Application of Oil Palm Liquid Waste significantly affect the parameter number of upperpart fresh weight and root weight. Interaction of both do not give a real effect to all of parameterobserved. The best result from this experimental were obtained in the treatment of compositionplanting media at 70% Sub-soil + 30 OPEB compost and application of Palm Oil Liquid Waste at 3litre/plant.Keywords: Planting Media, Palm Oil Liquid Waste, Oil Palm Seed
