Abstract


The aim of this study was to obtain organic vinegar suitable for the production of arbuscular mycorrhizal inoculums from the initial inoculum at different peat depths. The long-term goal is to obtain an alternative use of organic vinegar-based stimulants from rubber wood waste, fern roots and peat for the production of arbuscular mycorrhizal inoculums from peat soil. This study used an experimental method using a divided plot design (RPT) with a basic pattern of RAK. The first factor placed in the main plot is the depth of peat while the second factor is placed in subplots, namely organic vinegar. The number of FMA spores and FMA colonization of the roots was observed after breeding. The results showed that fertilization treatment had an effect on the production of inoculum, while the depth of extraction of peat soil had no effect in the production of arbuscular mycorrhizal inoculums. The average number of spores in each treatment was fertilizating commercial NPK fertilizers 2.788,33 spores, fertilizing rubber wood vinegar 2.194,67 spores, fertilizing fern root vinegar in 1934 spoes, fertilizing 1418 spores peat vinegar and without fertilizing 1.292 spores. Average percentage of root colonization produced was NPK commercial fertilizerz 71,67% (high), rubber wood vinegar 81,67% (very high), fern root vinegar 76,67% (very high), 50% (medium) peat vinegar and no fertilization 73,33% (high). Based on the analysis of rubber wood vinegar data, fern root vinegar and peat vinegar produced an average number of spores that were not significant compared to commercial NPK fertilizers, so that the three types of organic vinegar had the potential to stimulate arbuscular mycorrhizal inoculums in the form of spores and root colonization.Keywords: Arbuscular mycorrhizal inoculum, maize, organic vinegar, peat depth
