Abstract

In this work the possibility of using R program to stimulate transverse distribution of sprayed liquid deposition and coefficient of variation (CV) obtained on the virtual field beam. Agricultural flat fan nozzles were tested by testing equipment where individual influence from the nozzle with a constant pressure and transverse distribution of the sprayed liquid deposition were characterized. Deposition was collected on the patternator with grooves of 50 mm wide, deposition quantity was automatically measured in measuring vessels and obtained quantities were saved in the equipment database. Sprayed liquid deposition from a single nozzle with a definite influence is saved as a normal distribution. “R” computer program enables to set distributions obtained from single nozzles in such a way so that it was possible to stimulate the work of a field beam at 50cm agricultural nozzle spacing. In this way one can evaluate regularity of a sprayed liquid deposition and determine coefficient of variability for “virtual” field beam of the agricultural sprayer.
