| description | There is an ongoing search for technologies that guarantee soybean productivity. Among
them, the application of phytosanitary products stands out, since the sprayer is the most
required implement during the agricultural production cycle and each error, in practice,
represents a loss in the production process. With this in mind, the objective of this work
was to evaluate the volume captured and the characteristics of the application in the dif-
ferent thirds of soybean plants with variations in hydraulic nozzles and spray volumes, as
well as the use of electrification of the drops. To this end, a field experiment was conducted
during the 2018/2019 summer harvest in an experimental area at the University of Rio
Verde. The experimental design used was randomized blocks in a factorial scheme (3 × 4),
with four repetitions, in which the first factor consisted of three variations of spray nozzles
(simple fan, hollow cone and hollow cone with electrification of the drops). The second
factor involved four application rates (50, 100, 150 and 200 l · ha–1). The variables evalu-
ated were the number of drops per cm–2, percentage of coverage, volume median diameter
(VMD) and the captured volume (μl · cm–2). According to the results, for the upper thirds,
an increase in the application rate increased the volume of captured syrup. However, for the
lower third, the factors evaluated did not interfere in this characteristic. The hydraulic tips
influenced the density of droplets in the three thirds and the coverage only in the lower one.
The increasing rates of application, increases the density of drops and percentage of cover-
age in the different thirds of the plants. The evaluated factors had no effect on the syrup
distribution on the median abaxial surface of the leaves. |
