| dc.description.abstract | Soybean (Glycine max (L) Merrill) is one of the food crops as a source of vegetable protein. The purpose of this research was to determine the effect of rates of arbuscular mycorrhizal fungi (AMF) and the existence of sorghum, as an AMF host, on the growth and production of organic soybean. AMF was applied to each planting hole of soybean based on four different rates of 0, 1, 2, 2.5 g AMF hole-1. The existence of sorghum plant on the soybean plots, consisted of the presence and absence of sorghum in the plot. Both treatments were combined in nested design. Rates of AMF, in general, affected the growth and some yield components of soybean. Maximum growth was achieved at the rate of 2.08 g AMF hole-1. Soybean production was expected to increase in rate of more than 2.5 g AMF hole-1. Soybean productivity based on AMF rates were not significantly different, they were 1.35, 1.08, 1.04, and 1.15 ton ha-1 for 0, 1, 2, 2.5 g AMF ha-1, respectively. Without sorghum, soybean productivity was higher than that with the presence of sorghum, they were 1.25 and 1.05 ton ha-1, respectively. Improper placement of sorghum in the plot might have resulted in competition with soybean | en |
