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.

Highlights

Mechanized technologies in plant protection increase labor productivity, reduce relative costs, improve working conditions for workers, improve the quality of work and contribute reduce adverse effects on the environment.More and more new techniques for growing crops are entering in our agriculture
Today's agriculture is inconceivable without the use of various chemical plant protection products, as well as biological and mineral fertilizers to stimulate the growth and development of crops
Other authors [4] evaluate the use of ultrasonic sensors for variable speed automatic sprayers

Summary

Introduction

More and more new techniques for growing crops are entering in our agriculture This requires a very good knowledge of machines and technologies. In this regard, an interesting study was performed by [2, 3, 8] using a scanning system to assess the distribution of the working solution, both in the laboratory and in specific cultures in real time. How to optimize the solution distribution and reduce the spray diversion is suggested by [6]
