Abstract :

Application of liquid chemical on agricultural fields is mainly performed using hydraulic nozzle sprayers. However, in this study a dual-purpose disc agrochemical applicator for field crops was developed to boost agricultural mechanization in crop production and also to overcome the safety concern of hazardous spray drift during agrochemical application by the field crop farmers. The dual-purpose disc agrochemical applicator was tested with in order to determine the spray droplet size spectrum. The result shows that the average values of volume median diameter (VMD) range from 342-102 μm at 2000-5000 rpm rotational disc speed at different values of application rate for NASA glyphosate liquid chemical. The average value of the number median diameter (NMD) varies from 82 to 209 μm for NASA glyphosate liquid solution. The mean values of coefficient of uniformity for droplet sizes expressed as VMD/NMD found in this study were in the range of 1.25 to 1.63 for the liquid chemical.
