16552 Desempenho Produtivo da Cultura do Arroz Sob Efeitos da Microbiolização Bacteriana das Sementes e Aplicação de Agrosilício em Área de Assentamento no Maranhão Productive Performance of Rice Culture Under the Effects of Bacterial microbiolization Seed and Application of Agrosilício in Settlement Areas of Maranhão

Rice (Oryza sativa L.) is one of the most consumed cereal in the world, but has its production affected by several factors, including fungal diseases. This study aimed to evaluate the performance and the control spot grain of rice microbiolizado with Bacillus cereus and Bacillus sp., under cultivation with silicon fertilization calcium, magnesium and silicon. The experiment was a randomized blocks design split plot with five replicates, consisting of five treatments: 0, 1, 2, 4, 6 t / ha of calcium silicate and magnesium. The sub- plots had seeds of rice straw microbiolized wilt not microbiolized with B. cereus and B. sp, the concentration 107-108 (CFU / ml). There was no increase in the productivity of rice cultivated with microbiolized seeds with B. cereus and B. sp. under cultivation agrosilicio. As there was no reduction in the severity of grain staining.
