Abstract

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.   Key Words : Empty Oil Palm Bunch (EOPB) Compost, Biokom Biofertilizer, Cacao, Nursery

Abstract

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
