Silicon rates and beneficial microorganism on blast suppression and productivity of upland rice

One of the primary constraints in upland rice cultivation is disease blast (Magnaporthe oryzae), which can provide reduction up to 100% grain yield The use silicon with beneficial microorganisms (bioagents) be an alternative for control this and increase productivity grain. objective work was study effect rates bioagents suppression rice. methodology used tests carried out field conditions, two different areas: Capivara Palmital farms, during growing season 2015/2016. experimental design a split-plot scheme four replications. In main plots were fertilization (0, 2, 4 8 ton ha-1) subplots (1-without bioagents, 2-Pseudomonas fluorescens, 3-Burkholderia pyrrocinia, 4-Trichoderma asperellum, 5-a mixture three bioagents). results showed that 2 ha-1 best treatment leaf blast. Besides, from rates, 6 Farm provided highest yield. A sense, it concluded recommendation connect control, reduced amount bioagents.
