Arbuscular mycorrhizal fungi promote the growth and production of environmentally friendly grown shallots (Allium oscalonicum L.)

Abstract

Abstract This research aimed to study the effect of different formulas of organic liquid fertilizer and Arbuscular Mycorrhizal Fungi (AMF) inoculation level on the growth and production of environmentally friendly grown shallot. The study was carried out at the experimental farm of the Faculty of Agriculture, Universitas Hasanuddin, Makassar, from August to November 2015. Three formula of organic liquid fertilizer used was formula HNI.A (fresh cow feces + rice washing water + Annona muricata leaf extract), formula HNI.B (fresh cow feces+ rice washing water + banana fruit extract + banana peel extract), and commercial liquid Bioslurry (fermented cow urine). The inoculation of AMF applied was at the concentration of 0.50 g, 0.70 g, and 1 g per plant. The results show that the interaction between the use of liquid organic fertilizers and AMF inoculation affect some vegetative characters of shallots such as the number of leaves, the number of stems at 30 days after planting (DAP), and 55 DAP, and leaf area at 30 DAP. The highest shallot yield was in 0.7 g AM per plant, which was 3.32 tons per hectare compared to control of 1.68 tons per hectare.
