Abstract
Mechanization is essential for improving
farming processes, making the most use of resources, lowering costs, and
increasing operational efficiency. Novel spraying technologies are critical for
lowering costs, decreasing chemical effects, and increasing operator safety.
This improves crop health management efficiency, lowers pesticide use, reduces
environmental contamination, and promotes precision agriculture. Spraying is
generally done with a labor-carrying backpack sprayer, which needs more human
effort. So, to address the aforementioned issues, a manually operated wheel
sprayer is developed, which will benefit farmers in spraying and weeding
operations. Nozzle discharge rate increased sharply with operator speed above
2.5 km h⁻¹, peaking at 560 ml min⁻¹, but is unaffected by travelling distance
of the operator. Application rate inversely relates to both speed of the
operator and distance travel by the operator, reaching 74-76 l ha⁻¹ at minimum
speed and maximum distance, and falling to 62 l ha⁻¹ at high speeds over short
distances. The mean values of theoretical field capacity, actual field
capacity, field efficiency were estimated as machine performance data 0.44 ha h-1,
0.32 ha h-1 and 73 %.
