Abstract: 

The savannah soil is characterized by a lower fertility level. Thus, the study aimed to evaluate the effect of Trichoderma spp. inoculated in soil fertilized with natural phosphate in the growth of rice under greenhouse conditions. Twelve Trichoderma spp. isolates from savannah soil and one standard strain (T. harzianum) were used. The isolates were mixed to the soil fertilized with insoluble natural phosphate at a concentration of 2 x 108 conidia per gram of colonized rice, at a dosage of 100 mg kg-1 of soil, using pots with a capacity of 2.0 kg. Rice plants were evaluated for biomass production and phosphorus content. Then, UFT 25 and UFT 37 isolates were more efficient in rice growth and development, and showed higher phosphorus utilization efficiency. Most of the isolates showed to be directly involved in promoting the growth of this crop when compared to the uninoculated control, evidencing the potential of Trichoderma isolates as growth promoters of rice plants.
