Produtividade e qualidade de grãos de soja : eficiência na aplicação de Bioma FX Protection (CBMAI 1301)

Abstract

As it is a crop of great importance for both Brazilian agribusiness and the supply of protein worldwide, all aspects related to the production of soybeans are relevant. Thus, the objective of this study was to quantify the soybean crop yield and evaluate the physical quality of the grains comparing producer treatment and biological protective treatment, via foliar. The cultivation was carried out in an experimental station belonging to Consultancy Pastorello, located in Sinop - MT. The design was in randomized blocks, with 4 (four) treatments, being a control, with 4 (four) replications. The product evaluated was Bioma Fx Protecytion (Bacillus amyloliquefaciens) registered in MAPA under nº 30820. Ten plants per treatment were collected for agronomic evaluations. After collecting the samples (manual) and mechanical threshing, the samples underwent a manual cleaning process. The post-harvest analyzes performed were productivity; moisture content and 1000 grain weight according to the methodology described in Brasil (2009); bulk density (1 L cylinder); grain size and shape (MOHSENIN, 1986) and grain classification in terms of defects (MAPA, 2007). The results indicated that fungicide treatments have a significant effect on height and weight of grains per plant, with no difference between the producer treatment and the evaluated biological treatment; productivity showed no significant effect of treatments. In absolute increments, you have 10.8; 8.9 and 11.7 bags per hectare for T2; T3 and T4 compared to control; 1000 grain weight had greater increments when Bioma FX Protection was applied in 3 (three) applications, starting at V2/V3; the bulk density had better performance in the producer treatment, with the differential application of the mancozeb product at 25 to 30 DAE; for the size and shape of the grain, the producer treatment had lower values; the growing season was favorable for the production of few defects in the grains, with no difference between treatments.
