Effect of Indigenous Arbuscular Mycorrhizal Formulations with Cow Dung on Phosphorus Uptake, Growth and Yield of Local Corn ( Zea mays L.) in Marginal Land

摘要

Background and Objective: Bladygrass ( Imperata cylindrica ) that grows predominantly on marginal dry land can be utilized as an indigenous inoculum source of arbuscular mycorrhiza. It has many benefits, including helping plants absorb nutrients and water. Likewise, cow dung, which contains macro and micronutrients. Has the potential to fix of physical dan biological soil as well as soil fertility. The current research was carried out to study the effect various of arbuscular mycorrhizal formulations with cow dung to phosphorus uptake, growth and yield of local corn ( Zea mays L.) plant in marginal land. Materials and Methods: The study to analyze the effect of indigenous arbuscular mycorrhizal inoculum has been carried out in 2018 in The Field Laboratory of Faculty of Agriculture, Haluoleo University. The design used in this study was Randomized Block Design (RBD) in three groups with a single factor pattern, by using arbuscular mycorrhizal and cow dung treatments. Results: The result showed that in the rhizosphere there are various arbuscular mycorrhizal genus which is effective in increasing local corn yields in marginal dry land when combined with cow dung, too increasing of P plant uptake and available P in one month-old plant rhizosphere. Conclusion: The use of indigenous arbuscular mycorrhizal inoculum combined with cow dung of 80 g per planting hole to corn plant resulted in dry seed yield increasing to 3.85 t ha ? 1 , whereas in plants without arbuscular mycorrhizal inoculation and without cow dung did not produce seeds.
