This research aims to know antagonism of saprophytic and endophytic fungi against Fusarium oxysporum f. sp. cubens in Laboratory. The research was conducted at Plant Disease Laboratory, Agroecotechnology Program Study, Faculty of Agriculture, University of Sumatera Utara Medan from May to September 2014. It was done by using Completely Randomized Design (CRD) non factorial with seventeen treatments and three replications. The results showed all the saprophytic fungi (Gliocladium sp. and Acrostalagmus sp.) and endophytic fungi (Cephalosporium sp,. Pullularia sp., Aspergillus sp., Penicilium sp., Trichoderma sp. and Hormiscium sp.) potential as biological agents to control F. oxysporum f. sp. cubens in vitro. The best results obtained on Pullularia sp. with the ability to inhibit 60.577%. Interactions between saprophytic and endophytic fungi against F. oxysporum f. sp. cubens causing the hyphae of F. oxysporum f. sp. cubens malformations and lysis.Keywords: banana, Fusarium oxysporum f. sp. cubens, saprophytic fungi, endophytic fungi, nnninteraction

The research were to evaluate the effect of giving rice waste harvest and potassium fertilizer and its interaction to increasing potassium nutrient, the growth and the production of soybean (Glycine max (L.) Merill.). Already implementeded at gauze house and at laboratory Research and Technology of Agricultural Faculty of North Sumatera University, Medan from April to August 2014. The method used Factorial Randomized Complete Design with two factor and three replicatiosn. First factor is rice waste that is no giving rice waste (J0), straw compost 5 ton ha-1 (J1), straw charcoal 5 ton ha-1 (J2) and husk 5 ton ha-1 (J3) and the second factor is potassium fertilizer or Muriate of Potash (MOP) that is 0 kg ha-1 (K0), 50 kg ha-1 (K1), 100 kg ha-1 (K2), and 150 kg ha-1 (K3). The results showed that the rice waste increase K-exc and the highest by husk 5 ton ha-1 treatment. Potassium also increasing K-exc and the highest by 100 kg ha-1 treatment. Application of rice waste harvest and potassium fertilizer were not effected in soil pH, C-organic, K plant uptake, the growth, and the crop production.Keywords : straw compost, straw charcoal, husk, potassium fertilizer, soybean.

The purpose of the study to determine the characteristis of some of the physical, chemical, and biological properties of soil in organic farming systems. The study was held about 6 month from November 2013 to April 2014 in Bioenvironment Education Center of Organic Farming Bahorok in Timbang Lawan village, Bahorok, at Langkat district for observe the characteristic of some physical, chemical, and biological characteristic of soil in organic farming system. This research was conducted with survey method by evaluation the soil character in the area of farming base on the time of application of the organic farming, so it taken 3 samples which are the organic farming system beginning from year 2005; the organic farming system beginning from year 2010; and farming system which not applicate the system of organic farming yet as the comparation and was conducted about 3 sample points. The result of this research showed that the application of organic farming can fix the physical and biological characteristic, but not chemistry charactreristic yet. The charactreristic of physical of the soil that can be fixed by the application of organic farming were changed soil color become darken, decreased bulk density of soil, increased the total soil pore space, and increased soil permeability from criteria a bit slow to medium. Whether for the infiltration of soil can not be increased yet with the organic farming application. The application of this organic farming system can not fix the chemical characteristic of soil as pH of soil, C-organic of soil, N-total of soil, and P-available still have the same criteria with conventional farming application, but for parameter K-exchange can increase this parameter from low to medium. The organic farming application can fix the biology characteristic by increase the soil respiration, number of soil microorganism and earthworms population.Keywords : organic farming, conventional farming, soil characteristic

This study aimed to determine the level of the land suitability class of irigation rice (Oryza sativa L.) in Bakaran Batu village Sei Bamban sub district Serdang Bedagai regency. Conducted in Bakaran Batu village Sei Bamban sub district Serdang Bedagai regency and Geographic Information Systems Laboratory and Laboratory for Research and Technology Faculty of Agriculture, University of North Sumatra Medan in April to August 2014. Conducted using a survey that refers to the level of the limiting factors of land characteristics. Field observation data and the data matched the results of laboratory analysis (matching) with the criteria of rice land suitability classe. The results showed that there are 2 Unit Land Map (ULM) In Bakaran Batu village Sei Bamban sub district Serdang Bedagai regency. Extensive wetland area of 286.02 ha ULM 1 and area of 318.03 ha ULM 2. The actual land suitability classes for rice crops in the ULM 1 is marginally suitable / S3 rc, nr whereas potential land suitability class is marginally suitable / S3 rc. The limiting factor is the soil texture is permanent so it cannot be repaired. The actual land suitability classes for rice in the ULM 2 is the marginally suitable / S3 nr whereas potential land suitability class is moderately suitable / S2 nr. The limiting factor is the C-Organic and soil base saturation can be improved by liming, organic matter, straw composting and fertilizer containing K+, Ca2+, Mg2+, Na+ for example KCl, CaCO3, MgSO4.Keywords: land suitability evaluation, bakaran batu village, irigation rice

Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian ekstrak ganggang cokelat dan Bradyrhizobium japonicum serta interaksinya dalam meningkatkan hara nitrogen dan produksi tanaman kedelai. Penelitian dilaksanakan di Rumah Kasa dan Laboratorium Biologi Tanah Fakultas Pertanian USU pada Juni-Oktober 2014, menggunakan Rancangan Acak Kelompok (RAK) faktorial, dengan 2 faktor dan 3 blok. Faktor pertama adalah konsentrasi ekstrak ganggang cokelat yang terdiri dari 4 perlakuan (0, 10, 20 dan 30 % / polybag) dan faktor kedua adalah Bradyrhizobium japonicum yang terdiri dari 2 perlakuan (tanpa dan dengan Bradyrhizobium japonicum). Hasil penelitian menunjukkan bahwa pemberian ekstrak ganggang cokelat berpengaruh nyata meningkatkan jumlah dan bobot bintil akar, berat kering tajuk, bobot biji, dan serapan N tanaman, namun tidak berpengaruh nyata meningkatkan N total tanah. Pemberian Bradyrhizobium japonicum berpengaruh nyata meningkatkan jumlah dan bobot bintil akar dan berat kering tajuk, namun tidak berpengaruh nyata meningkatkan N total tanah, serapan N tanaman dan berat biji. Hasil terbaik diperoleh pada kombinasi konsentrasi ekstrak ganggang cokelat 20%.Kata kunci : ekstrak ganggang cokelat, Bradyrhizobium japonicum, nitrogen, kedelai
