| Resumo: |
The objective of this research was to study the biomass production, plant architecture and Si and Mn uptake in rice plants cultivated in a Acrustox fertilized with silicon and manganese. The experiment was carried out in a greenhouse using a 2x5 factorial (0 and 1000mg dm-3 Si x 0, 4, 12, 16 and 20mg dm-3 Mn) with four replications, in a randomized block design. The application of Si to the soil resulted in a smaller leaf insertion angle, a greater Si content in the leaves and roots and biomass production. Moreover, Si caused the decrease content of Mn in leaves and its increase in roots. With the rising dose of Mn, there was an increase in the content of this element in soil, roots and leaves, regardless of the Si application and reduction in biomass production of rice in the larger doses only when the Si was not added to the soil.
