Propagation of mycorrhiza as biological fertilizer and its application on patchouli seedling in Andisols Bener Meriah

Abstract

Mycorrhiza, functioning as a biofertilizer, have the capacity to improve soil fertility, including Andisols which is cultivated by patchouli. This research objective to produce mycorrhizal as a biofertilizer to increase the growth of patchouli. Additionally, the effect of mycorrhizal types on the seedlings of patchouli in Andisols was studied. Propagation mycorrhizae carried out the exploration of mycorrhizae on Andisols Bener Meriah, and the carrier was Glomus mosseae, Gigaspora, and a mixture of Glomus mosseae and Gigaspora sp. and then the mycorrhizal biofertilizer was tested to patchouli seedling. The parameters observed in this study included the colonization of patchouli root, initial soil analysis, and patchouli seedling growth. The output in this study is a product in the form of a local specific strain of Bener Meriah biofertilizer. The results obtained have succeeded in the propagation mycorrhizal biofertilizers with the carrier Glomus mosseae, Gigaspora, and a mixture of Glomus mosseae and Gigaspora sp. The highest 90% mycorrhizal colonization was found in the mixed mycorrhizal carrier Glomus mosseae + Gigaspora sp. The growth of patchouli seedlings increased, and the highest patchouli growth was observed the combination of mycorrhizal Glomus mosseae and Gigaspora sp. application
