One of the factors that determine the quality of cocoa seedlings are growing medium that has achemical and physical fertility, in order to obtain a good and healthy seeds for furthergrowth.Growing media fertility can be improved or enhanced with inorganic or organic fertilizer,such as Rabbit manure, which is one type of solid waste rabbit manure and NPK fertilizer, isexpected to increase the growth of cocoa seedling. This research had been conducted atexperimental field of Fakultas Pertanian USU in July 2013 until September 2013, using factorialrandomized block design with two factor, i.e. dose of rabbit manure (0, 50, 100, and 150 gram perpolybag) and dose of NPK fertilizer (0 ,4, 8, and 12 gram per polybag). Parameter observed wereplant height, stem diameter, number of leaf, summarize of leaf area, fresh weight of shoot, freshweight of root, dry weight ofshoot and dry weight of root. The result showed response of rabbitmanure on cocoa seed significantlyincrease plant height, total of leaf area, and dry shoot weight.The best results from this experimental were obtained in the treatment of rabbit manure at 150g/polybag.________________________________________________________________________________Keywords: Rabbit manure, NPK Fertilizer, Cocoa Seedling

Several farmers in the Village of Air Hitam Sub District of Lima Puluh District of Batubara wereused the impact of Rice-Watermelon cropping system because production of rice was descended inevery years and to increasing the use irrigate efficiency. The difference in cropping system and thelong inundation result differences paddy soil properties. This research analyzed the soil pH, Al-dd,Al saturation, Fe3+, and Cation Exchange Capacity (CEC) of land in the village of Air HitamSub District of Lima Puluh District of Batubara with altitude of 14 meters above sea level. Theresearch start to do on May until November 2012. The results of analyzed was procced by t-analyze.The showed that soil pH, Fe3+, CEC on Rice-Rice cropping system is lower than the Rice-Watermelon, while Al was higher in Rice- Rice cropping system than Rice- Watermelon.Keywords: Al, Fe, paddy soil, cropping system

“The Effectiveness of Botanical Insecticides Test to Mortality the Leptocorisa acuta Thunberg.(Hemiptera : Alydidae) on rice plant in Greenhouse”. The research was held at the Greenhouse OfAgriculture Faculty University of North Sumatera, Medan since June – August 2013. The methodof this research was Completely Randomized Design Non Factorial with 8 treatments and 3replications. Treatments being tested is K0 (control), A1, A2, A3 (25, 50, 75 ml tuba rootextracts/litre of water), T1, T2, T3 (25, 50, 75 ml tobacco extracts/litre of water), and AT (50 mltuba root extracts/litre of water + 50 tobacco extracts/litre of water). The parameters includethe percentage of mortality pest and the death of imago. The result showed that the most effective ofbotanical insecticides was found in treatment AT (100%) at 3 days after application, followed by T3(100%) at 4 days after application and T2 (96,67%) and A3 (95%) at 5 days after application, andless effective was found in A1 (81,67%) and T1 (88,33%) at 5 days after application, and on the 6days after application all botanical insecticides treatmens has show 100% mortality. The death ofimago is the fastest in treatments AT, T3, T2, A3, A2 and T1 occurred at 1 day after planting, andlongest are on treatments A1 occurred at 2 day after planting.Keyword: botanical insectisides, L. acuta, mortality, the time death

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
