Abstract
ABSTRACT The aim of this study was to evaluate the effect of inoculation with rhizobium and co -inoculation with Azospirillum brasilense on phytometric characteristics of peanut plants grown in Latossolo Vermelho (Oxisol) with and without compaction. The experiment was conducted in a greenhouse, with a randomized block design in a 5x2 factorial scheme and 4 replicates, totaling 40 experimental units. Treatments were composed by commercial inoculant for peanuts (SEMIA 6144 strain); MT 15 strain; combination of MT 15 + A. brasilense; nitrogen control and absolute control. Plant height, number of leaves, number of branches per plant, stem diameter and Falker chlorophyll index were evaluated. The data were subjected to analysis of variance and, when significant, to Tukey test at 1% probability level. For the variables plant height, number of leaves, number of branches and stem diameter, the results were similar for all treatments, except for the absolute control and number of branches at 90 days after emergence (DAE) and stem diameter at 30 and 90 DAE. For stem diameter at 30 DAE, the results were similar to those found in the treatments with co -inoculation, commercial inoculant and nitrogen fertilization. There was interaction for Falker chlorophyll index at 60 DAE, with the best result found in the MT 15 strain. Inoculation with MT15 and co-inoculation with A. brasilense promoted good performance in peanut crop in terms of phytometric characteristics in soil with and without compaction.

INTRODUCTIONPeanut (Arachis hypogaea L.) is a legume crop rich in oil, proteins, vitamins, carbohydrates and minerals, and can be consumed fresh or used for various other purposes, such as for the manufacture of food, medicinal products and for oil extraction (LOBO et al, 2012)

Process, especially in the formation and activity of nodules (MOREIRA, SIQUEIRA, 2006). All these interferences cause changes in the biochemical functioning of crops, restricting shoot growth (FARIAS et al, 2013) and production (ROSSETI, CENTURION, 2018). An alternative to this process may be related to the use of microorganisms, especially nitrogenfixing and/or plant growth-promoting ones, to evaluate what benefits inoculation and coinoculation could bring to plants in a compacted environment
