The regression analysis of technical factors on the drift and droplets size at the spraying by using from Laboratory and software

To evaluate the technical factors affecting drift and droplet size of turbo liner sprayer and its regression analysis while spraying, a research was conducted in canola fields at the Ramin Agriculture and Natural Resources University of Khuzestan in1394 year. Three-factor factorial experiment with three replications in a completely randomized design was performed. The first factor was the pressure of the sprayer with three levels (10, 25 and 35 bar), the second factor was fan speed with two levels (1998 and 2430 rpm) and the third factor was forward speed at two levels (9 and 13.5 km/ hr). With increasing spraying pressure, fan speed as well as forward speed, the drift was increased and the droplet size and sediment were decreased at the level of significant 1% value. According to the results of linear regression analysis for drift, sediment and droplet size, the pressure has the greatest effect on drift, DV50 and sediment.
