Propagation Techniques of Mycorrhizal Bio-fertilizer with Different Types of Mycorrhiza Inoculant and Host Plant in Entisol Aceh

Abstract

Background and Objective: This study aimed to produce of mycorrhizal bio-fertilizer in entisol Aceh and to reduce farmers dependence on inorganic fertilizers. Especially, in coastal areas of Lampuuk Aceh Besar with order entisol soil has been constrained to crop management. The soil is not only low-content of nitrogen, phosphorous and potassium but also not optimally absorbed by plants. Besides, the availability of water to be absorbed by plants in entisol also limited. Strategies to overcome these constraints, we need to produced mycorrhizal bio-fertilizer by different types of mycorrhizal inoculants and host plants and applied it to increase the productivity of entisol and crop. Propagation of mycorrhizal bio-fertilizer was carried out by using three types of mycorrhizal inoculants consisted of Glomus mosseae, Gigaspora sp., mixing Glomus mosseae and Gigaspora sp. on the host plants of maize and white sorghum, respectively. Methodology: This experiment was arranged in a non-factorial randomized block design with three replications. The parameters observed included the quality of mycorrhizal bio-fertilizer following of mycorrhizal infection on host plant, spore population, root fresh weight and root dry weight. Results: The results showed that the types of mycorrhizal inoculant and host plant affected the quality of mycorrhizal bio-fertilizer. Conclusion: The inoculation of mycorrhizal with the starter Glomus mosseae+Gigaspora sp. and the host plant of corn gave the best results and have the potential for propagation techniques of the mycorrhizal bio-fertilizer on entisol Aceh.
