The effect of Planting Media Compound and Biokom biofertilizer to Growth of Cacao (Theobroma cacao L.) in Nursery, supervised by Ir. BALONGGU SIAGIAN MS dan Ir SANGGAM SILITONGA. The design of the experiment was randomized block design arranged in factorial with two factors. The first factor was planting media, 100% Subsoil Ultisol + 0% EOPB Compost, 75% Subsoil Ultisol + 25% EOPB Compost, 50% Subsoil Ultisol + 50% EOPB Compost, 25% Subsoil Ultisol + 75% EOPB Compost. The second factor is Biokom biofertilizer, 0 g/polibag, 3 g/polibag, 6 g/polibag, 9 g/polibag. The Parameter observed includes plant height (cm), number leafs (sheet), diameter of stem (mm), total of broad leaf (cm2), fresh and dry weight of crown (g) fresh and dry weight of root (g). The result of research showed that planting media influential significantly to plant height 12 and 14 weeks after planted, number leafs 8, 10, 12, 14 weeks after planted, diameter of stem 8, 10, 12, 14 weeks after planted, fresh and dryweight of crown. Present of manure in fluential not significantly on plant height, number of leafs ,diameter of stem, total of broad leaf, fresh and dryweight of crown and freshweight of root. Interaction between planting media and present of fertilizer influential not significantly on plant height, number of leafs ,diameter of stem, total of broad leaf, fresh and dryweight of crown and freshweight of root.

Land evaluation is the process of estimation of the potential of the land for a variety of alternative uses. Land evaluation involves conducting a survey or research shapes the landscape, nature and distribution of land, and the distribution of vegetation types and aspects of other land. This research aims to determine the level of suitability for irrigated rice in Air Hitam Village Lima Puluh District Batubara Regency. This research was conducted in Air Hitam Village Lima Puluh District Batubara Regency and Technology Laboratory of Agriculture Faculty in May 2011 - April 2012. This research uses the method of limits refers to the level of the limiting factors of land characteristics. The data observed in the field (the physical environment) and the data matched the results of laboratory analysis (matching) with the criteria of suitability class irrigated rice land. The results showed that the limiting factor on irrigated land is soil depth, soil texture, and base saturation. Soil depth and soil texture can not repaired while the base saturation can repaired with the addition of organic matter. Keywords: land suitability evaluation, irrigated rice

Application of inorganic fertilizers continuously without the use of organic fertilizers has caused the degradation of agricultural land. The negative impacts caused by land degradation is a decline in agricultural yield, such as the yield of shallot. A solution to solve this problem is to combination inorganic with organic fertilizers. Coffee pulp compost is one of the example of organic fertilizers. So, the research was conductedto investigate combination of NPK fertilizer and coffee pulp compost on growth and production of shallot which is use Randomized Block Design withtwofactors. Firstfactor is NPK fertilizer (0, 150,300, 450kg/ha) and thesecondfactor is coffee pulp compost (0,5, 10, 15 ton/ha).The results showed that the treatment of NPK fertilizer significantly affect the plant height 3,5,6 weeks after planting and production per plot.NPK at 150 kg/ha can increase production by 15.32% compared with no fertilization.Coffee pulp compost treatment significantly affect the production per plot.Compost at 10 ton/ha can increase production by 10.26% compared to without giving compost. The interaction between the NPK fertilizer and coffee pulp compost non significantly affect to all parameters.

The study aims to calculate the disease severity of cocoa black pod (P. palmivora) at several smallholder’s cocoa plantations with different shade in Langkat district. The study was conducted in five smallholder’s cocoa plantations that have different shade in Langkat, which is unshaded cocoa plantation at Karang Anyar village, Secanggang sub-district, suren shaded cocoa plantation at Karang Anyar village, Secanggang sub-district, banana shaded cocoa plantation at Sambirejo village, Binjai sub-district, palm oil shaded cocoa plantation at Sambirejo village, Binjai sub-district, mixed shaded cocoa plantation at Tanah Seribu village, Sei Bingai sub-district with altitude ± 28 m asl and at the Laboratory of Plant Disease Faculty of Agriculture, University of North Sumatera with altitude ± 25 m asl. The method of research is survey. Results showed that highest disease severity of black pod rot found at cocoa that shaded by bananas located in Sambirejo village, Binjai sub-district which reach 73.40 %, and the lowest was founded at cocoa plantation that shaded by suren located in Karang Anyar village, Secanggang sub-district which reach 12.80 %. Keywords : severity, Phytophthora, cocoa, shade.

attempts to do that is the use of high yielding varieties. This study aimed to determine the effect of four doses of Trichoderma extent on the growth and production of some onion varieties, which have been implemented in Simalingkar, excl. Tuntungan Field from May to August 2012. This study used a randomized block design factors ie double dose Trichodema first factor with 4 levels, namely 0 g (control), 1 g , 2 g , 3 g dose. The second factor is that varieties: Medan, Bali Karet, Maja. The data obtained were analyzed using analysis of variance, followed by Test Honestly Significant Difference The results of data analysis showed that the varieties differ significantly in plant height, number of leaves, number of cloves per sample, cloves per bulb diameter. Dose Trichoderma significantly different height and dry weight of plants per plot. Interaction between Trichoderma doses and varieties have significantly influenced all parameters.

The research of land capability classification survey is held on the area of water capturing (DTA) of Danau Toba. Land capability classification is fulfilled by using scoring methods based on the land unit in DTA of Danau Toba. The scorring of limitation factor of each land unit is held to obtain land capability class. Here are the limitation factors of each land unit: the depth of efectivity land, texture, drainage, permeability, slope, erotion, flood and surface stone.The research outcome shows that there are totally 36 land units which are divided into 8 land capability classes. Land width of the first class is 26.484.59 ha, the second class is 73.422.64 ha, the third class is 32.912.79 ha, the fourth class is 28.442.06 ha, the fifth class is 21.751.94 ha, the sixth class is 2.749.55 ha, the seventh class is 618.26 ha and the eight class is 30.155.78 ha. Keywords: land capability class, land unit, scorring.

Onionis one of the leading vegetable seed which has long cultivated. Demand onioncontinues to increase, so that production needs to be increased, where one attempts to do that is theuse of high yielding varieties. The availability of local varieties provide many options, it alsodecrease the use ofimported seeds, it is necessary to test the power of high yielding varieties inother areas.This research was aimed to select shallot varieties that able to adapt in Medan lowland.This research was conducted on level land in Simalingkar, Tuntungan District (± 25 meters abovesea) in June-September 2012. This research used Randomized Block Design (RBD) treatmentconsisting of five varieties are Katumi, Yellow, Sembrani variety, Medan and Tuk-Tuk variety, thetreatment was replicated four times. The data obtained were analyzed using analysis of variancefollowed by Duncan’s Multiple Range Test (DMRT). The results of showed that varietiessignificantly different with number of tillers, fresh weight plant sample, dry weight plant sample,tuber diameter, tuber height and tuber water loss and production. Of the five onion varieties testedshowed not significantly in variables plant height, number of leaves, harvest, fresh weight plant plotand dry weight plant plot.

Tomato plants originated from Mexico to Peru region. At the present time the tomato hasbecome more developed, modern cultivars or hybrids can grow well and produce the climate ismuch different from the place of origin. This study aims to create drought tolerant plant of tomatovarieties. The research has done in Tissue Culture Laboratory Fakultuty Agriculture UnivercityNort Sumatera, Medan since Juli-September 2012. Using a completely randomized design with twofactors, that is Polyethylene Glicol (PEG) (0,5,10,15,20%) and Tomato varieties (TO-244, Niki,Kartika, Mio, Super Hawai) with four replications. Observation variable is living root forminginitiation, total of root, and high of roott. The result of research has shown that PEG is significantfor root forming initiation and high of root, but not significant for total of root.
