Bioativador em plantas de cobertura e efeito na biomassa da cultura da soja

Abstract

The use of alternative means of fertilization is part of the search for new planting technologies. Among these technologies, green fertilization and the use of bioactivators stand out. Cover plants or cover crops are important for maintaining the physical, chemical and biological characteristics of the soil, as well as for improving the level of nutrients and organic matter in the soil. The cover plants help in the decomposition of the soil, provide a greater diversity of roots and consequently in the biodiversity of the soil, besides performing nutrient cycling. In addition, the technology of bioactivators is new in the market, and its action is to promote, inhibit or modify the morphological and physiological processes of the plant, to improve its performance and also its sanity. Thus, the present work has the objective of evaluating the dry and green mass production of the soybean crop, planted on the use of green fertilizer and bioenergetic Penergetic [marca registrada]. The project was developed in the city of São Jorge D'Oeste, in Latossolo Vermelho. Two plots of 1000m2 were used, and one plot received the bioactivator application and the second plot did not receive. In both areas there was the intercropping of forage turnip and rye. For the analysis of the cover plants, the botanical separation was carried out. After the desiccation of the cover plants, the Penergetic-k [marca registrada] bioactivator was applied to help the decomposition of the green matter and activating the decomposition processes. After the application of the bioactivator, about 30 days, the soybean crop was planted. The results show that for both the cover crops and the soybean crop the dry matter production was higher where the bioactivator was used, with masses of dry matter of 2243.6 kg ha-1 for Turnip, 994.3 Kg ha-1 for Rye and for soybean crop 833.78 kg ha-1. In the research it was evidenced that the greater accumulation of dry matter mass and nutrients for the green fertilization in the area with bioactivator and the soybean plants stood out in the vigor and biomass production also in the test area with bioactivator.
