Sažetak
Research is conducted on a vineyard with a Hardi Zaturn axial fan sprayer. The influence of major technical spraying factors (type of nozzle, working speed and spray volume) were observed on coverage of the treated area. The working speed of sprayer was set at 6 and 8 kmh-1, and spray volume on 250, 300 and 350 lha-1. In research, Lechler blue (TR 8003C), yellow (TR 8002C) and green (TR 80015C) nozzles are used. The research was set as three - factorial field experiment with 18 treatments in 4 repetitions. Sixty water sensitive papers (WSP) were used for the treatment, which was processed with digital image analysis (DIA) and ImageJ software. The major technical spraying factors have a high significant statistical impact (**) on the main property of the research. By decreasing the ISO number of nozzles and by increasing the working speed and spray volume, we found the increasement of area coverage.The best adjustment of technical spraying factors (area coverage of 51.45%) was achieved with a green nozzle (TR80015C), working speed of 8 kmh-1, spray volume of 350 lha-1, and working pressure of 19.53 bar. The lowest area coverage was achieved with a blue nozzle (TR 8003), working speed of 6 kmh-1, spray volume of 250 lha-1, and working pressure of 19.53 bar.
