Abstract

 Increased soybean production  is  competing with the extension of the  use of agricultural land for  non- agricultural needs. Therefore the future expansion of agricultural land can only use marginal lands such as peatlands, wetlands and tidal lands. This paper discusses the growth and production of soybean varieties Anjasmoro in saline environments. Varieties Anjasmoro have total leaf area and the percentage ratio of the canopy  which  is  not  significantly  different  from  the  other  varieties  tested  except  Kipas  Merah.  In  the production of components, seed weight Anjasmoro 100 seeds varieties including higher and statistically the same as the varieties Kipas Putih dan Kipas Merah

Abstract

An experiment to study the effect of host species and source of nutrient on spore production of an ArbusculeMycorrhizal Fungus, Gigaspora margarita, has been carried out. Combination treatments studied consisted ofhost species (Zea mays and Pueraria javanica) and nutrient factor (no fertilizer, fertilizer and Red Hyponex).Growth medium used was a mix of soil and sand in 1: 1 ratio (v/v) which was sterilized. Results of the experimentshowed that spore production of G. margarita was affected by host species and also by nutrient applied, thoughthere was no interaction between the two factors. However, P. javanica produced more spore than Z. mays.Treatment with Red Hyponex result much higher spores than others, but however without fertilizer produced morespores than Urea, TSP and KCl fertilizers.

Abstract

Rule of Arbuscule Mycorrhiza Fungi on Growth of Leucaena leucocephala Under Salt StressABSTRACT. Symbiosis Arbuscule Mycorrhiza Fungi (AMF) and plant were not only improving growth and nutrition absorption, but also crop tolerance salinity. Increasing of tolerance to salinity following colonization of AMF promising due to phosphate absorption more efficient. Phosphate absorption of mycorrhizal plant mount equal to 115% compared to non-mycorrhizal plant. This issue will improve growth of crop and decrease influence of toxic ions. Mycorrhizae also can lessen forming of proline equal to 64.47% one of the way of osmotic adjustment of non mycorrhizal plant to increase tolerance. Despitefully accumulate sodium in mucorrhizal plant lower than non mycorrhizal, were degradation of sodium accumulation equal to 61.58%.

Effectiveness of Arbuscular Mycorhiza and Shanding in Growth of Teak SeedlingABSTRACT. Interaction between mycorrhizal inoculan dosage with level of shade was significantly affected of seedling growth of height, total dry weight matter, soot root ratio, P content, and degree of infected root by mycorrhizal. The usage of mycorrizal inoculants dosage at 10 g per seedling which combined with level of shade 75% gave the best for seedling growth of teak for siz moth old. Increasing level of shade 25% to 75% increased seedling growth of teak. Furthermore, seedling of teak that treated mycorrzal inoculants dosage at 100 g per seedling was more significantly affected of seedling growth than 5 g per seedling.

Abstract

Forest fire affect chemical, physical and biological properties of the soils. In the biological properties of the soil, forest fire also affects number of microorganisms and activity of microorganisms. The purpose of this research is calculate the value of soil microorganism with various periods of forest fires. The measure of the activities of microorganism using jar and titrimetri methods.The result of this research showed that value of  respiration in  unburn soil is 11,99. Value of respiration from forest fire soil in 2010 is 6,43. Value of respiration from  forest fire soil in 2011 is 10,28. Value of respiration from forest fire soil in 2012 is 16,28. Value of respiration from forest fire soil in 2013 is 11,14. Value of respiration from forest fire soil in 2014 is 8,14. Activity of microorganisms is almost the same between the occurrence of fire with soil unburn. Keywords: forest fire, soil microorganism, activity of microorganism

Abstract

The forest fire effect chemical, psysical and biological propesties of the soil. In the biological of soil, forest fire also effect the existence of phosphates solubilizing fungi. This research was conducted to determine the presence of Phosphates Solubilizing Fungi  in the former soil of fired forest by the time of the fire in Samosir Regency. Soil samples taken from former soil of fired forest and unfire forest at a dept 0 – 20 cm around rhizosfir. Soil analysis carried out in Research and Technology of University of North Sumatera along with isolation and identification phosphates solubilizing fungi at the Laboratory Soil Biology Agroekoteknologi Studies Program Faculty of Agriculture, University of North Sumatera. The result showed that there were similitary and differences phosphates solubilizing fungi in former soil of fired forest and unfire forest. Phosphates solubilizing fungi consisting of 2 fungi genus there are Aspergillus and Penicillium. Keywords: Forest Fire, Phosphates Solubilizing Fungi

Abstract

Arbuscular Mycorrhizal Fungi (AMF) are cosmopolitan is almost found in a variety of ecosystems. Forest fires influence the biological properties of the soil, especially AMF. This research aims to study the status and diversity of AMF in the former soil of forest fires. Samples of soil and roots of plants was taken from the location of the fire in separate incidents during the 5 period and location unburn. Parameters observed that the degree of root infection, spores density and identification of the type of spores. Identification of mycorrhizae conducted at the Laboratory of Soil Biology, Faculty of Agriculture, University of North Sumatra, begin in May until September 2014. Morphology characteristics used to identify the type of AMF is a form of cell wall thickness, presence or absence of substanding hyphae, surface smoothness and spores  reaction to melzers. The results show that an increase in the average density of spores from the field and the results of trapping, for the average percentage of AMF colonization in the roots of plants at 50,65% include grade 3 and 4 or high categories. Found 2 genus, namely Genus Acaulospora and Genus Glomus. Of the field found as many as 35types of spores and trapping results are found as many as 40 types of spores. Key words: Arbuscular Mycorrhizal Fungi (AMF), Forest fire

Abstract

Existence and Status of Arbuscular Mycorrhizae Fungi is affected by biotic and abiotic factor. The goal of this research is to know diversity of Arbuskular Mycorrhiza Underneath of durian (Durio zibethinus), kemiri (Aleurithes moluccana), asam gelugur (Garcinia atroviridis), and karet (Hevea brasiliensis). Soil sample has been taken from Arboretum Universitas Sumatera Utara under of four tree of MPTS. This research use soil separating method to obtain spores and root coloring method to find out root colonization. The obtained an average spore density on kemiri is 42 spores/50 g soil, durian is 42 spores/50 g soil, karet is 50 spores/50 g soil and asam gelugur is 62 spores/50 g soil. The result shows on four tree of MPTS obtained 23 spores types of Glomus and 8 spores types of Acaulospore with colonization percentage of durianis 25,6%, kemiri is 43,86%, Karet is 49,6% and Asam Gelugur is 50,5%.

Abstract

Plumbum (Pb) is an environmental contaminant that risk for human’s health, reducing soil fungtion and productivity and damage for plants. Therefore, remediation is need to do such as bioremediation using AMF and sengon as a host. A research was conducted to knowing the effect of the addition of AMF for Pb content on Sengon in green house of Agriculture USU. Analyze of Pb metal was done at Research Laboratory of Pharmacy USU on October 2014- February 2015 using faktorial completely randomize design with two faktors, i.e Pb addition (0 and 400 ppm) and doses of mycorrhiza inoculation (0, 25 and 50 g). Parameters measured were root colonization, plant height, stem diameter, root drying weight, crown drying weight, crown root ratio, root Pb content, crown Pb content and soil Pb content after harvest.The results showed that Pb addition affected significantly on plant height, Pb content on root, crown and soil after harvesting parameter. Inoculation of mycorrhiza affected significantly on plant height, stem diameter, drying weight of root and crown. Inoculation of mycorrhiza did not significant on Pb content but capable to increasing Pb content on root, crown and soil. The interaction of the two faktors did not affected significantly on all parameters. Key words: Sengon, Pb, AMF
