Abstract

This study aims to find out the influences and interactions of cellulolytic microorganisms providing inorganic fertilizer on the growth of palm oil and determine cellulolytic microorganisms dosage and proper inorganic fertilizer on plant oil palm in immature palm plants phase II. Research was done on plantations PT. Tunggal Perkasa Plantation Air Molek District Pasir Penyu, sub-province Indragiri Hulu Riau Province. Research carried out for 4 months starting in October 2012 to the month of January 2013. Randomized Design Block (RDB) factorial with two factors namely cellulolytic microorganisms and inorganic fertilizer with 3 replications used on this research. Data was analyzed using ANOVA and extended with further experiments on standard 5% DNMRT. Parameters of the observation was numbers of total frond, long fronds (cm), number of leaflets (sheets), hump circumference (cm) and plant height (cm). The results showed the granting cellulolytic microorganisms 20 mL / plants and the provision of fertilizer inorganic 1/4 x dose can be suppress the use of fertilizers of inorganic up to 75% on growth oil palm in immature palm plants.

Abstract

Giam Siak Kecil Biosphere-Bukit Batu (GSK-BB) is Riau  peatlands area which is largest composed by lowland peat swamp forest ecosystem. Seeing peatland ecosystem getting extreme, there will be small possibility that soil microbes are able to breed optimally, but microbes in tropical land has not been explored. However, the high content of organic matter, allowing soil microbial activity in the organic matter recycle that essential to life such as nitrogen cycle. Non-symbiotic nitrogen fixing bacteria is a free-living bacteria and plays a role in the supply of N in the soil. The results of the isolated and characterization of single bacterial isolates obtained 31 non-symbiotic N fixing of GSK-BB peat Biosphere which allegedly largest to genus Azotobacter, Azospirillium and Clostridium pasteurianum as well as the results of clear zone isolates on the medium modification, from the single isolates contained 14 isolate that potentially in a non-symbiotic N with the largest ratio of clear zone obtained HTA1 10-4 NS-2, HTA1 10-4 NS-1, HTA 4 10-4 NA-1 dan HTA5 10-4 NS-2.
