Compatibility and effectivity of various mycorrhizal sources with cassava varieties in Gunungkidul

Abstract

This study aims at understanding the interaction between various mycorrhizal sources and three local cassava varieties of Gunungkidul, specifically on their compatibility, population, mycorrhizal diversity, and their effect on cassava growth. The experiments were conducted based on Completely Randomised Design (CRD) with experimental factors using three treatments in triplicates. The experimental factors included three cassava varieties and various sources of mycorrhiza. The results demonstrated that among the interactions of various mycorrhizas with three local cassava varieties of Gunungkidul, the highest infection was seen from Mentega cultivar inoculated with indigenous mycorrhiza of the Alfisol soil of Gunungkidul (95%). Mycorrhizal diversity using indigenous mycorrhiza of Alfisol soil was higher than mycorrhiza of pandan rhizosphere and commercial inoculant, and the dominant mycorrhiza type was of spores belonging to genus Glomus. On the other hand, the indigenous mycorrhiza of Alfisol soil inoculant on various cassava varieties demonstrated similar effect and yielded the same number of spores, root length, and plant dry weight; despite the fact that on Kirik cultivar growth, the significant difference was observed on the plant height, leaf number and fresh net weight.
