Abstract
Aims: This study aims to determine the optimal dosage of Fungi Mycorrhizal Arbuscular (FMA) to enhance the growth and yield of shallots (Allium cepa var. aggregatum) in Ultisol.
Study Design: The research was conducted from February to April 2024 at the Agronomy Experimental Station and Laboratory, Faculty of Agriculture, University of Bengkulu, at an altitude of ±10 m above sea level.
Methodology: A completely randomized design (CRD) with one factor was used, consisting of five FMA dosage treatments (0, 10, 20, 30, and 40 g inoculant/plant), with four replications, resulting in 20 experimental units. Each unit consisted of three plants, totaling 60 shallot plants.
Results: The application of FMA significantly influenced shallot growth and yield, particularly fresh and dry shoot weight and fresh onion bulb weight. At a 40 g inoculant/plant dose, FMA can increase fresh and dry shoots and bulb weight by 24.83%, 2.51%, and 50.65%, respectively, compared to without FMA application.
Conclusion: The application of FMA at a dosage of 40 g inoculant/plant effectively enhances shallot growth and yield, particularly in shoot and bulb weight.
