For a proper and successful establishment of avocado crop, plants with a developed and healthy root system are needed. However, in commercial avocado nurseries, management oriented to root improvement is not carried out. The objective of this study was to evaluate the effect of root biostimulants based on microorganisms and organic acids on growth, chlorophyll content and mycorrhization in avocado plants. There were seven treatments, including one control. The experimental design was completely random, with eight repetitions. The variables evaluated were number of leaves, plant height, main root length, SPAD units, root dry weight and percentage of mycorrhization. In each of the variables, the best treatment was the combination Nutrisorb® L + Biofit® RTU, which confirms that the use of microorganisms and organic acids favors vegetative and root growth, as well as promotes greater mycorrhization.
