Jurnal Agroekoteknologi Vol 5, No 2 (2017)
Publisher : Universitas Sumatera Utara

Penelitian ini bertujuan untuk mengevaluasi hara N, P, K tanah, respon pertumbuhan dan produksi tanaman bawang merah varietas Medan terhadap pemberian pupuk kandang kerbau dan dosis pupuk anorganik di Desa Unjur Kecamatan Simanindo Kabupaten Samosir dan analisis tanah dilakukan di Laboratorium PT Nusa Pusaka Kencana, Tebing Tinggi. Penelitian ini dilaksanakan pada Januari sampai April 2016. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) 2 faktor yang terdiri dari 2x5 taraf yaitu K0 (0 ton/ha pupuk kandang kerbau), K1 (15 ton/ha pupuk kandang kerbau), P0 (0 kg/ha NPK, 0 kg/ha ZA, 0 kg/ha KCl), P1 (65 kg/ha NPK, 65 kg/ha ZA, 15 kg/ha KCl), P2 (130 kg/ha NPK, 130 kg/ha ZA, 30 kg/ha KCl), P3 (195 kg/ha NPK, 195 kg/ha ZA, 45 kg/ha KCl), Px (800 kg/ha NPK, 400 kg/ha ZA, 0 kg/ha KCl) dengan jumlah ulangan sebanyak 3 ulangan. Hasil penelitian menunjukkan bahwa pemberian pupuk kandang meningkatkan panjang tanaman, bobot basah umbi dan bobot kering umbi bawang merah. Pemberian pupuk anorganik meningkatkan hara N dan P tanah, akan tetapi pada dosis tinggi, semakin tinggi dosis pupuk anorganik yang diberikan dapat menurunkan hasil produksi bawang merah. Produksi tertinggi terdapat pada perlakuan K1P1 (15 ton/ha pupuk kandang kerbau, 65 kg/ha NPK, 65 kg/ha ZA, 15 kg/ha KCl). Kata Kunci : bawang merah, pupuk anorganik, pupuk kandang kerbau

This study aims to evaluate the effect of rice husk biochar and coffee husk biochar, to evaluate difference effect of rice husk biochar and coffee husk biochar and to know effect of difference dose of rice husk biochar and coffee husk biochar on phosphate and zinc, and rice growth in the paddy soil with high total P. The research was conducted on the greenhouse, Faculty of Agriculture, University of North Sumatra, Medan. The soil which used from the paddy soil in Lubuk Dendang, Perbaungan, Serdang Bedagai which has the high total P. The experiment was carried out using completely randomized design with 7 treatment : Control; 10 ton/ha rice husk biochar; 20 ton/ha rice husk biochar; 30 ton/ha rice husk biochar; 10 ton/ha coffee husk biochar; 20 ton/ha coffee husk biochar; 30 ton/ha coffee husk biochar. The Analysis of data used the analysis of variance and contrast orthogonal test.Experimental results showed that rice husk biochar and coffee husk biochar has significant effect on levels of Zn plant, but not significant effect on soil pH, available P, soil Zn HCl 25%, levels of P plant, P uptake, Zn uptake and the growth of plants. Coffee husk biochar has more potential than rice husk biochar to increasing levels of Zn plant. Dose of coffee husk biochar 20-30 ton/ha increasing levels of Zn plant higher than 10 ton/ha.

The purpose of this research was to know the effect of organicmatter application to increasing organic carbon, P – available, and Zn - available in paddy soil. Thisexperiment was conducted in green house and Laboratory of Research and Technology AgricultureFaculty Univesity of Sumatera Utara, Medan from March until July 2016. Soil samples were takenat Lubuk Dendang village, Serdang Bedagai district. The research used non factorial randomizedcomplete design with eight treatments and three replications, consist of A (control), B (cow manure10 ton/ha), C (rice husk biochar 10 ton/ha), D (straw compost 10 ton/ha), E (cow manure + rice huskbiochar 20 ton/ha), F (cow manure + straw compost 20 ton /ha), G (rice husk biochar + straw compost20 ton/ha), and H (cow manure + rice husk biochar + straw compost 30 ton/ha). Parameters observedare include soil pH, organic carbon, P – available and Zn – available. The result showed that all kindof organic matters and biochar which used in this research have no effect on increasing soil pH, Zn –available but have same effect on increasing organic carbon and P – available.Key words : biochar, organic carbon, organic matters, P – available, Zn -available

Land area with criteria critically / semi critically at Bah Sumbu sub watershed area is 8742,949 hectares or 79,41% of the total entire Bah Sumbu Sub Watershed. This research was conducted to study texture, organic carbon and acidity of the soil moderate critical area of land at Bah Sumbu sub Watershed, Gunung Datas , Raya Kahean Subdistrict. The research was conducted by using survey method with soil sampling randomly based on some vegetations and slopes. Soil samples was taken at each vegetation for 3-6 samples. Analyzed of soil pH with methods electrometry, soil organic matter with Walkley and Black method, and soil texture with Hydrometer Bouyoucos method. Based on the results of soil analysis of several land uses in Gunung Datas Village, Bah Sumbu sub-watershed area is known that soil pH is included in very acidic to slightly acidic criteria with acidity range of 3,73 to 5,82. The C-organic content is included in very low to moderate criteria with a range of organic carbon between 0,77% to 2,02%, and the texture is dominant sandy loam soil texture.Keywords: vegetation, texture, pH, organic carbon

PENGARUH KOMPOSISI MEDIA TANAM DAN APLIKASI Azotobacter chroococcum TERHADAP PERTUMBUHAN STEK TANAMAN TIN (Ficus carica L.) Saniar Fauza; T. Sabrina; Hamidah Hanum
Jurnal Pertanian Tropik Vol. 3 No. 1 (2016): JURNAL PERTANIAN TROPIK
Publisher : Talenta Publisher

Perbanyakan tanaman tin umumnya dilakukan dengan stek batang atau cabang. Pertumbuhan stek dipengaruhi oleh faktor luar dan faktor dari dalam. Faktor luar diantaranya media tanam dan faktor dalam yaitu kandungan hormon, salah satu bakteri fiksasi N2 non simbiotik yang dapat mensekresi hormon pertumbuhan tanaman yaitu bakteri Azotobacter chroococcum. Penelitian dilakukan untuk menentukan komposisi media tanam dan aplikasi Azotobacter chroococcum dalam pengembangan pembibitan stek tanaman tin (Ficus carica L.). Penelitian telah dilaksanakan di desa Gampong Raya Dagang Kecamatan Peusangan, Kabupaten Bireuen, Provinsi Aceh dari bulan November 2014 sampai dengan Juni 2015. Rancangan yang digunakan adalah Rancangan Acak Kelompok Faktorial, Faktor pertama yaitu media tanam (M) terdiri dari enam komposisi : (top soil + pasir + Pupuk kandang sapi), (top soil + pasir + kompos jerami C/N<20),(top soil + pasir + kompos jerami C/N>20), (top soil + pasir + zeolit 5g), (top soil + pasir + kompos jerami C/N<20 + 5g zeolit), (top soil + pasir + kompos jerami C/N>20 + 5g zeolit), Faktor kedua yaitu aplikasi bakteri Azotobacter chroococcum (A) terdiri dari : (tanpa aplikasi A.chroococcum) dan (aplikasi A.chroococcum). Hasil penelitian menunjukkan bahwa interaksi antara komposisi media tanam dan aplikasi A.chroococcum berpengaruh nyata terhadap pH media, kadar N daun dan berat kering daun, dan tidak berpengaruh nyata terhadap panjang cabang, jumlah ruas,waktu munculnya tunas , karbon organik dan N total media. Komposisi media tanam top soil + pasir + kompos jerami C/N>20 + 5g zeolit + 5ml A.chroococcum dapat memberikan efek yang lebih baik terhadap pertumbuhan tanaman tin dibandingkan dengan komposisi media lain.
