Abstract: The pineapple cv. BRS Imperial developed by Embrapa Mandioca e Fruticultura has excellent agronomical and sensorial attributes with great market acceptance. However, the cultivation of plants is time-consuming with low performance and slow growth, limiting adoption especially by large-scale pineapple growers. Therefore, the aim of this study was to evaluate the growth potential of bacteria from the associated microbiome of Ananas spp. in order to validate its application in different stages of cultivation (semi-field, in vitro and greenhouse), for the production of seedlings on a large scale. Eighteen treatments consisting each of a different bacteria from the biological collection of microorganisms associated with the Ananas genus, were tested under semi-field conditions. Three treatments (BAC25, BAC222 and BAC406) were selected to validate the microbiolization process of pineapple seedlings from the cv. BRS Imperial in vitro (rooting stage) and in vivo (acclimatization in the greenhouse) together with a mixed treatment (composed by the combination of the three bacteria) and a control treatment (untreated plants). The in vitro cultivation was carried out in commercial substrate autoclaved with MS nutrient medium where bacterial suspensions were added according to the treatments mentioned above. Each treatment consisted of 120 replicates, totaling 600 experimental units. The evaluations were carried out at weekly intervals for a period of 42 days, when destructive analyses were performed. The remaining plants were transferred to the greenhouse and evaluated from this stage until complete acclimatization. For the in vivo validation, the bacterial suspensions were applied to the substrates contained in plastic cups, with pineapple seedlings of the cv. 'BRS Imperial', totaling 200 plants per treatment. The evaluations consisted of measuring growth variables and destructive analysis. The data obtained were subjected to analysis of variance and the means grouped by the Scott-Knott test at 5% probability. The BAC25, BAC222 and BAC406 treatments promoted plant growth and biomass increment in semi-field conditions. BAC406 was the most promising in promoting growth of pineapple seedlings in vitro, while BAC222 was the best treatment for the in vivo cultivation. The results obtained demonstrate that the bacteria tested have great potential for use in the different stages of cultivation of micropropagated seedlings, improving growth, health and vigor of plants.

The determination of the spatial distribution of soil moisture in the field is relevant for many purposes in agriculture and engineering, but it is still a challenge, since standard determination methods have limitations and problems of representativeness. Electrical resistivity may be used with this finality, but this method is still poorly studied for highly weathered tropical soils, which present structural and textural peculiarities. This work aims to present the calibration of the moisture/electrical resistivity relationships for a typical tropical soil, and to evaluate its robustness as a soil moisture prediction method. A highly weathered clay soil (Oxisol), representative of the Brazilian savanna (?Cerrado?), was sampled and the resistivity tests of the A, Bw and C horizons were conducted in a four-electrode cell array. The A and Bw horizons of clay Oxisols usually present resistivity values greater than temperate soils counterparts, which can be attributed to the lower content of highly active clays and higher macroporosity. The soil electrical resistivity/volumetric moisture relationship present a nonlinear and inverse trend and the generalized form of Archie?s law has the potential to be applied to determine the water content of these soils. The electrical resistivity/volumetric soil moisture semi-log plot showed a two-step pattern, with a remarkable change in the behavior around the moisture associated to the wilting point. The field validation shows that the use of the electrical resistivity is possible for the measurement of soil moisture and for the subsurface mapping of its horizons.
