| Sumario: | In the present work the application effect of nematophagous fungus
Purpureocillium lilacinum over the availability of soil nutrients and the yield of oats
plants, using an agricultural soil was evaluated. Two experiments were conducted under
greenhouse conditions, one with soil in natural conditions and other with autoclaved
soil. In each experiment were handled two treatments with 20 replicates in a completely
randomized design; one with the application of P. lilacinum and the other without the
fungus application as a control. The soil chemical characteristics: pH, C, N, P, K, Ca,
Fe, Cu and Zn were analyzed at the beginning and at the end of the experiment. The
variables evaluated on oat plants were: height, fresh and dry weight, nutrients, number
of spikelets per plant and the spikelets weight. There were no significant differences
between treatments in plants height, the nutrient content of the soil and plants in both
treatments, neither in fresh and dry weight in the experiment with natural conditions
soil. The positive effect of fungus application was reflected on the greater fresh and dry
weight in the experiment with autoclaved soil and the greater number and weight of
spikelets of oat plants in both experiments.
