The aim of this work was to evaluate the influence of Brettanomyces custersianus on the metabolic activity of Saccharomyces cerevisiae during the tumultuous stage of wine production. The Cabernet Sauvignon grape must with the skin was inoculated with individual cultures of Sacch. cerevisiae and with mixed cultures of Sacch. cerevisiae and Br. custersianus. During the 6-day tumultuous phase of fermentation, the highest ethanol production and the highest sugar consumption were obtained with the strains without B. custersianus. Fermentations carried out with the addition of Brettanomyces metabolites, acetic acid and 4-ethylphenol, showed that only the former inhibited the growth of both Sacch. cerevisiae strains used. In some cases, Br. custersianus could affect the rate higher alcohols production and their final concentrations during the tumultuous phase of vinification. |

Variable rate application of fertilizer has the potential to improve nutrient use efficiency, improve economic returns, and reduce negative environmental impacts. The objective of this study was to evaluate the variable rate application of potassium fertilizer to soybean crop in a no-till system. The study was conducted on a 13-ha soybean grain field in Carambeí, State of Paraná, Brazil in a Typic Hapludox. The area has been under no-tillage for more than 10 years growing grains (soybean, wheat and maize) in rotation with a cover crop (oat). Four treatments were used: control, 40, 80 and 120 kg ha-1 of K2O applied as KCl. Narrow strip plots of 18 X 1,000 m were assigned in three blocks within the 13-ha field. In each strip plot grain yield was continuously evaluated at the harvest time with a combine equipped with yield monitoring and a real-time global positioning system unit (GPS) without differential correction. Data storage in geographical information system (GIS) was used to fit the kriged yield map. Soybean average yield was 3,838 kg ha-1, and spatial differences in yield were observed with grain yields ranging form 2,100 to 6,583 kg ha-1. These differences occurred where previous analysis showed soil texture variation. Maps of K exportation by grains indicated that the uniform rate fertilizer would not replace adequately the K fertilizer. These results showed that the recommendation map for variable rate of potassium fertilization can be accomplished by the yield maps from the past years. These results showed that VRT of potassium for this plot could be performed based on yield maps, and it could be used in reducing yield variability and maintaining profitability while optimizing K applications.
