Abstract

The pot experiment were carried out to study effect of Arbuscular Mycorrhizal Fungi (AMF) inoculation and rice straw 1\um1c substances treatment on yield of maize on Ultisol. The experi ent was conducted to obtain optimum rates of AMF and rice straw humic substances, which will be used as a guide to determine various rate of treatment in field experiment. The experiment used randomized block design and treatments were replicated four times. The first factor were AMF: 0,1,2 and 3 t.ha·1 and the second factor were rice straw humic substances: 0,0.25, 0.5 and 0. 75 t.ha·1. Results showed that the highest yield of dried maize grain were 5.2 t.ha·1 at the AMF optimum dosage of 2.4 t.ha·1 and rice straw humic substances of0.9 t.ha·1. Keywords: AMF, rice straw humic substances, maize
