The Colonization Vesicular Arbuscular Mycorrhiza in Different of Dosage Form in the Root Tissue of C3 and C4 Plants

A study aimed to identify and determine the percentage of Vesicular Arbuscular Mycorrhiza (VAM) structure colonies in C3 and C4 Plant Root Tissues as Biological Agents in Different Dosage Forms was conducted from May 2022 to August 2023. At coordinates 3°59'30" S and 119°38'43" E, an altitude of 37.0 m above sea level. This study used a factorial design. Factor 1 is the form of VAM dosage consisting of powder/control, sachet, and tablet dosage forms. In contrast, the other factors are the types of plants, namely Pueraria javanica, Vigna radiata, Amaranthus tricolour from the C3 plant group and Saccharum officinarum, Zea mays, Sorghum bicolour from the C4 plant group. The parameters observed were the level of colonization of VAM structures on plant roots in the form of hyphae, arbuscules, vesicular, and spores.The results of the study showed that the VAM dosage form did not inhibit colonization of the roots of C3 and C4 plant groups with different levels of colonization percentage by VAM structures; the level of VAM colonization in the Sachet dosage form had a higher colonization level, and a more complete VAM structure was found compared to other VAM dosage forms. The novelty found in this study is that the mycorrhizal sachet dosage form has a better colonization rate than the powder and tablet dosage forms in C3 and C4 plants.
