Abstract

ABSTRACT“Study of Biomass total and The Grass Carbon Reserves and Charateristhic of soil Chemistry incatchment area of Lake Toba: case study at kecamatan Silahisabungan Kabupaten Dairi”. To knowthe biomass production total and carbon reserves and charateristhic of physical chemistry of soil.This study have been done an December 2011 to March 2013. Samples of soil,biomass, and litterwas taken from three types of slopes, they are quite ramps, wavy and a bit steep. The method ofbiomass measurement is “Destructive sampling method” by cutting over all plants part on the landwith the windth is 2m x 2m. Then separated each part , crots, leaves and trunk and pondered the dryweight. The result of this study showed that the biomass production total on grass land is greaterthan on forest land bur charateristhic of physical chemistry of forest lans was better than the grassland.Keyword : biomass, grass, slope, Toba lake water catchment area

Abstract

This study aimed to determine the role of Mycorrhizae on plant Cd uptake P and mustard(Brasicca juncea L.) as well as the availability of P and Cd in fed Andisol phosphate fertilizer. Theresearch was conducted in the Greenhouse, Soil Biology Laboratory, and the Laboratory ofResearch and Technology Faculty of Agriculture, University of North Sumatra, Medan, in July2012-March 2013. This study uses a randomized block design (RBD) Factorial. The first treatmentwas a factor with two levels of mycorrhizal inoculum M0 (0g) and M1 (20g), the second factor isthe treatment of phosphate fertilizer (SP-36) with 4 dose levels, P0 (0g), P1 (0.97g), P2 (1.94g ),and P3 (3.88g) with 3 Deuteronomy thus obtained 2x4x3 = 24 experimental units. The parametersmeasured were the canopy dry weight, root dry weight, P uptake, mustard plant (Brasicca juncea L.)Cd uptake, the degree of mycorrhizal infection, levels availbility of P and Cd levels Andisol. Theresults showed that administration of Mycorrhizae increase the dry weight of the canopy, the degreeof infection of the roots, P uptake and plant-available soil P levels. Phosphate fertilizersincreased the dry weight of the plant canopy and P uptake, and tend to increase levels of P and Cdsoil and plant P uptake but not statistically.Keywords: andisol, phosphate fertilizer, and mycorrhizae.

Abstract

Tujuan penelitian adalah untuk menguji potensi dan kompatibilitas Mikoriza Vesikular Arbuskular (MVA) dengan bibit karet (Hevea brasiliensis MUELL Arg.) stump klon PB 260 yang masih mempunyai daun payung dua, berasal dari Balai Penelitian Sungei Putih di rumah kasa.  Uji potensi dan kompatibilitas dilakukan menggunakan rancangan acak kelompok (RAK) non faktorial dengan tiga ulangan, dan delapan perlakuan MVA yaitu dua isolat MVA indigenous karet, lima isolat MVA koleksi laboratorium Biologi Tanah FP USU dan tanpa MVA (kontrol).  Diinnokulasikan spora MVA sesuai perlakuan dilakukan dengan memberikan sebanyak 20 spora per polybag disekitar perakaran bibit tanaman karet. Pengamatan dilakukan setelah terbentuk daun payung tiga. Variabel yang diamati meliputi derajat infeksi akar oleh mikoriza, serapan hara P, dan pertumbuhan tanaman. Hasil penelitian menunjukkan bahwa dari beberapa isolat yang diujikan ternyata isolat Acaulospora sp 1 (kuning besar) dan isolat Acaulospora sp 2 (kuning kecil) mempunyai kemampuan beradaptasi yang tinggi dengan bibit tanaman karet yang diujikan, ditunjukkan oleh derajat infeksi akar yang tinggi yaitu 55% dan 48% yang berbeda sangat nyata dari perlakuan lain.  Untuk serapan unsur hara P, tanaman yang diinokulasi dengan  kedua isolat ini mempunyai kandungan P yang tertinggi, masing masing 34 mg P dan 35 mg P.  Kedua isolat ini adalah isolat koleksi Laboratorium FP USU.  Masa penelitian uji potensi ini hanya 7 minggu menyebabkan perlakuan terhadap beberapa variabel yang diamati  tidak berpengaruh nyata.  Diterima : 18 Oktober 2013; Direvisi : 8 November 2013; Disetujui : 12 Desember 2013 How to Cite : Hanafiah, A.
