The aim of this study was to identify the effect of the different levelsand frequencies of foliar application of the biofertilizer L-glutamic acid in oregano seedlings produced in the organic system, quantifying their growth. The treatments were arranged in a completely randomized design with four replications in a 3 x 2 factorialarrangement, consisting of two doses (0.4 and 0.8 ml L-1) of a compound with 30% L -glutamic acid and a control, under a frequency of two applications, with a total of 4 applications for the 7-day frequency, and 2 applications for the 14-day frequency. At the 62nd day after sowing, eight plants were collected per replication for measuring biometric characteristics of shoots and roots. The biofertilizer L-glutamic acid affected the evaluated characteristics, and the dose of 0.8 ml L-1 (applied with a 14-day interval), promoted greater seedling growth of oregano.
