EFFECTS OF PRESSURE AND HEIGHT ABOVE TARGET ON DISCHARGE RATE, SWATH WIDTH AND DROPLET SIZE FOR AN ANIMAL DRAWN HYDRAULIC SPRAYER
Publication Date : 01/02/2017
An animal drawn hydraulic boom sprayer of 100 liters tank capacity was developed using locally available materials and its performance evaluated. In field testing, discharge rate (ml/min), swath width (m) and droplet size 𝜇𝑚 (vmd) were used as performance indicators. And operating pressures (15, 30 and 45 psi) and heights above target (30, 40 and 50 cm) as independent variables. Results revealed that the effects of operating pressures and heights above target were found to be of great influence to the discharge rate, swath width and droplet size statistically. Effective field capacity of 1.04 ha/hr and 89.6% field efficiency was determined. Comparing the results with what was obtained using the manually operated knapsacks sprayer represents 59% and 64% increase in discharge rate and swath width respectively. The finding of the research study presented in this paper could be used to boost agricultural mechanization during the application of liquid chemical on field crops.
