Efeito do produto microgeo nos componentes de produtividade de trigo e soja, e sobre colêmbolos no solo

Abstract

The present study has the general objective of evaluating the effect of the use of biological fertilization on the productivity and yield components of wheat and soybean grains. The research took place in the municipality Barra Funda, Rio Grande do Sul, and had the winter and summer cereals tested with the application of Microgeo in a DBC experiment. The treatments used were, control without application of Microgeo, one application of Microgeo and two applications of Microgeo, all in the recommended dosage for perennial cultures of 150 L¹. The variables analyzed for wheat were, number of tillers, number of ears, total productivity, the weight of a thousand grains and hectoliter weight. For soybean, plant population, the number of pods, total productivity and weight of a thousand grains were used. The analyzes were submitted to statistical analysis by the Tukey test at 5% probability by the Sisvar program. The results show that the product showed significance for some variables such as the number of tillers in experiment 1 and plant population in experiment 2, showing no difference between one application and two applications. It also showed that an application of Microgeo® is not toxic for collembolans Folsomia candida.
