An experimental investigation of working with ordinary and electromagnetic nozzles

Abstract

The great variety of plant protection equipment, the shape, length and slope of the cultivated area, the type of sprayers used and the professional skills of the operator require an individual approach to each sprayer and cultivated area. The aim of this study was to compare the area of the double-treated sections when working with ordinary and electromagnetic nozzles at different slopes of the treated area. For the analysis, actual field coverage data were used when working with the Amazone self-propelled sprayer - Pantera 4502, with a boom width of 24 m, half of which is equipped with electromagnetic nozzles and the other half - with ordinary nozzles. It was found that when working with ordinary nozzles, the area of overlap increases with increasing degree of overlap and the angle of inclination of the section boundary. The area of overlap when using ordinary nozzles is almost 3 times larger than when using electromagnetic at 100% overlap of the treated areas. Regression models, surfaces and lines were obtained, with the help of which the area of overlap in each section of the treated field can be determined.
