The objective of this research is to study the effect of combination of volcano sand, zeolite, and sea water to soil chemical properties and the production of rice plant local varieties. This research was conducted in highland peat, village of Hutabagasan Sub District of Dolok Sanggul Distric Humbang Hasundutan North Sumatra. This research used non factorial RAK with four treatments, those are G0 (control), G1 (volcano sand 5 kg), G2 (5 kg + volcano sand sea water 2.5 L), G3 (volcano sand sea water 5 kg + 2.5 L + zeolite 1 kg) and 3 replicants. The results showed that the addition of volcano sand 5 kg + sea water 2,5 L + zeolite 1 kg decreased the pH of the soil, K - exchange, Ca - exchange and percentage base saturation, increased the value of the electrical conductivity (EC), Na - exchange, Mg - exchange. The addition of volcano sand 5 kg + sea water 2,5 L + zeolite 1 kg decrease dry weight of the plant and the number of grains per panicle.Keywords: volcano sand, zeolite, sea water, highland peat soil, Rice

Research in Dairi aims to determine the relationship between altitude and soil organic carbon content of the ability FAM infection through stages of field sampling and direct observation in the laboratory , conducted from December 2013 - January 2014. The object is the roots of coffee plants , given the pre- observation treatment by 10% KOH soaking , HCl 2 % soaking and in a solution of trypan blue soaking . Then do the calculation ability of mycorrhizal infection by comparing the number of infected root surface and the total of roots surface were observed . The results showed that the degree of mycorrhizal infection on the roots of coffee plants positively influenced by altitude and soil organic Carbon content.Keywords: Mycorrhizae, Coffee Plant, Altitude, Organic Carbon

Respons Pertumbuhan Bibit Stek Mucuna (Mucuna Bracteata D.C) Pada Media Tanam Limbah Kelapa Sawit Dan Mikoriza M. Dian Munawan; Chairani Hanum; Mbue Kata Bangun

The objecctive of these research was to study response of Mucuna seedling on planting media from waste oil palm and mycorrhiza. This research conducted at the Silau Dunia, PTPN III, District Dolok Masihul, Serdang Bedagai, North Sumatra, on October 2014 to January 2015. The design used randomized block design factorial. The first factor was planting media from palm oil waste with composition: (Top Soil+ Sandy soil; Top Soil+ empty fruit bunches+ Fiber; Top Soil+empty fruit bunches+Solid Decanter; Top Soil+empty fruit bunches+Sludge; Top Soil+ Fiber+ Solid Decanter; Top Soil+ Fiber+ Sludge and Top Soil+ Solid Decanter+ Sludge). The second factor was asosiation with Mycorrhizae (micofer aplication and not). The result showed that planting Media Top Soil+ empty fruit bunches+ Sludge can increased Mucuna growth. Mucuna seedling that symbiosis with mycorrhizae can improve all growth parametrs compared without mycorrhiza aplication.Keywords : Cuttings Mucuna, empty fruit bunches, Fiber, Sludge, Solid Decanter, Mycorrhiza

Respons Pertumbuhan dan Produksi Tanaman Kedelai Varietas Detam 1 terhadap Pemberian Vermikompos dan Pupuk P Novita Sari Sihaloho; Nini Rahmawati; Lollie Agustina P Putri

Publisher : Universitas Sumatera Utara

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian vermikompos dan pupuk P terhadap pertumbuhan tanaman kedelai. Penelitian ini dilaksanakan di lahan percobaan Fakultas Pertanian USU (± 25 m dpl) pada Maret – Juni 2015 menggunakan Rancangan Acak Kelompok faktorial 2 faktor yaitu pemberian vermikompos (0, 0,25, 0,5 dan 0,75 kg/polibag) dan pemberian pupuk P (0, 0,625, 1,25 dan 1,825 g/polibag). Parameter yang diamati antara lain tinggi tanaman (cm), diameter batang (mm), umur berbunga (hari), bobot basah akar (g), bobot kering akar (g), bobot basah tajuk (g), bobot kering tajuk (g), volume akar (ml), jumlah cabang produktif, jumlah polong per tanaman, jumlah polong berisi, bobot 100 biji kering (g) dan umur panen (hari). Hasil penelitian menunjukkan bahwa pemberian vermikompos dan pupuk P berpengaruh nyata terhadap semua parameter kecuali umur panen (hari) dan bobot 100 biji kering. Interaksi antara vermikompos dan pupuk P berpengaruh nyata terhadap umur berbunga tanaman kedelai. Hasil yang terbaik diperoleh pada dosis vermikompos 0,75 kg/polibag dan pupuk P 0,625 g/polibag.Kata kunci : vermikompos, Pupuk P, kedelai

Kajian Erosi Kualitatif Pada Budidaya Tanaman Karet Rakyat Usia 15 Tahun di Desa Lau Damak Kecamatan Bahorok, Kabupaten Langkat Achmad William Halimas; Abdul Rauf; Mukhlis Mukhlis

Qualitative Erosion Studies on The Rubber Cultivation of The People Age 15 Years In the village of Lau Damak Bahorok subdistrict Langkat. The study aims to determine the qualitative erosion in the area of cultivation by using descriptive method with sampling technique based on stratified random sampling method. Research analyzing various parameters such as pH level of soil fertility, texture, Cation Exchange Capacity (CEC). Organic C, N-total, P-available, K can be exchanged (K-dd) and Bulk Density. The results show that the qualitative erosion that occurs in the area of rubber cultivation people aged 15 years in the village of Lau Damak Bahorok subdistrict Langkat cause terangkutnya nutrients P and K to the valley as well as the value of the levels of C-organic and N-total high value of land in the back caused by a number of existing litter above the soil surface.Required soil and water conservation efforts in the form of ground cover (cover crop) as well as the manufacture of terracing on slopes to prevent soil erosion.Key words : Descriptive, Qualitative erosion, Stratified Random Sampling.
