Abstract

Soybean desiccation is a practice that can only be used in the area of grain production to control weeds or standardize plants with green leaf retention problems. However, some positive results have been obtained regarding the effectiveness of desiccants in maintaining the quality of soybean seeds. Based on the above, the objective of this work was to verify the behavior of drops produced as a function of the spray volume, as well as to define the most suitable spray volume for an application of desiccants. The test was conducted in the field at the Experimental Farm for Research and Extension Teaching - UniBRAS, in the municipality of Rio Verde / GO (in the Southwest region of Goiás 17 ° 45'08 ” S and 50 ° 55'53” C and altitude 754m) at 2020/21 agricultural harvest. The experiment was installed in a randomized block design with 4 replications and 5 treatments (different spray volumes 80; 110; 140; and 160 L ha-1, being composed by the presence and presence of the adjuvant. volumetric (DMV), the relative amplitude (AR), percentage of droplet volume with a diameter less than 100 μm (Dv <100), accumulated volumetric diameter of 10% and 90% (respectively D 0.1 and D 0.9), coverage area and drop density, coefficient of homogeneity (SPAN), volume deposited (L ha-1) Data were analyzed using an analysis of variance. When significance was found for a given variable, a regression analysis was used. The spray volume of 160 l/ha-1 influenced the behavior of drops produced and the application of 110 l/ha-1 became viable for desiccating the crop, presenting good coverage uniformity and 30% higher operational yield.
