In Ecuador, the cultivation of oil palm has great economic importance within the agricultural production of the country, with an area sown of 248,199 hectare . Currently there are a large number of reports that encourage the use of microorganisms, especially those that can fix nutrients that are of high energy cost and therefore reduce their use, helping the sustainable management of plantations. The objective of this work is to evaluate the agronomic behavior of oil palm seedlings (Elaeis guineensis Jacq) in symbiosis with efficient soil microorganisms. The experimental work was carried out in the lands of the "Los Zapatas y Bonilla" property owned by Mr. Alberto Zapata, located in the El Cisne enclosure in the Montalvo corner, 1.5 km from via El Tambo. We evaluated 8 treatments and an absolute control, with three repetitions. The sowing was carried out in plots of 10 covers with a total area of 29.64 m2 which was used as vegetable material the variety of palm ¨CIRAD¨ type Deli x La Me. The treatments were distributed in a completely randomized Block design. For the evaluation of means, the Tukey test was used at 95% probability. At 30, 60 and 90 days, plant height, stem diameter, number of leaves per plant, root length and leaf area were evaluated. In turn, mycorrhizal analyzes were performed to determine spore counts, population analysis of bacteria that made the substrate, percentage of colonization and endophyte density. The results showed that the inoculation of Mycorrhizae with doses of (330g / h) benefited the seedlings with the highest growth of the seedlings, diameter of the stem and foliar area at 3 months. In the same way, the treatment that presented the highest economic income according to the sale of the seedlings was generated with the application of Mycorrhizae (330g / h) with 236.7 dollars / hectare of net profit.
