Mycologists consider fungi as one of the most significant organisms because many beneficial aspects. They ensure healthy growth and the development of the plants as well as act as decomposing agents for dead plants. Arbuscula mycorrhiza (AM) is a one of the beneficial group of obligate (can’t grow and develop without host plants) fungi and is characterized by the existence of arbuscules ( type of mycorrhiza in which the fungus penetrates the cortical cells of the roots of a vascular plant). Mycorrhiza is the symbiotic association between a fungus and the roots of a vascular host plant Therefore; this mushroom is also termed as arbuscula mycorrhiza fungi. Arbuscula mycorrhiza can be effortlessly developed in the rhizosphere of various plant species1. Various research outcomes showed improvement in metabolism, growth and crop production of Arbuscula mycorrhiza through its application in corn plant. Arbuscula mycorrhiza can increase nutrient status and uptake2,3, growth4,5, reduce the effects of soil compaction stress6,7, increased crop resistance in competition with weeds8.
Unfortunately, the output of corn plant, particularly in Southeast Sulawesi, Indonesia is lesser as compared to its genetic potential. Because; many plants are being cultivated with little technology applications chiefly the less utilization of organic and biological fertilizer. Rachmawati Hasid, Makmur Jaya Arma and Andi Nurmas conducted an experiment to examine the presence of AM and evaluate its ultimate impact on growth and productivity of corn plant.
Two set of experiments were performed during this investigation. First trial was termed as existence Arbuscula mycorrhiza in rhizosphere of dominant weed (bladygrass) in dry land in Kendari, Southeast Sulawesi, Indonesia, was observed descriptively. While in the 2nd experiment, effect of Arbuscula mycorrhiza to several variety of corn plant (Zea mays L.) in Marginal dry land was evaluated. Randomized Block Design (RBD) was followed; consisted of eight treatments corn variety.
Satisfactory outcomes were observed which exhibited that spore populations were found in rhizosphere of dominant weed was 792-901 spores 100 g–1 soil, 70-90% roots infection. Symbiosis consequence of Arbuscula mycorrhiza with plant growth showed that Phosphorus uptake was highest in Batu Putih variety of corn plant. On the other hand; the highest yield was determined in Dana variety. It can be concluded from this research that existence of Arbuscula mycorrhiza in dominant weed rhizosphere; in dry land is far above the ground. The response of various varieties of maize plants to particular fungi indicates that local varieties have a higher adaptability in comparison with newly introduced varieties.
