A self-propelled intra-canopy boom spraying system was designed for spraying chemicals
in small height row crops. The performance of the spraying system was evaluated both
under laboratory and field conditions to assess the efficacy and minimize the loss of spray
liquid. Flat fan and hollow cone nozzles were tested to determine the boom volumetric
distribution, swath and spray angle at different combinations of pressure and height. The
flat fan nozzle gave better volumetric distribution at 2.5 kgf.cm-2, while the hollow cone
nozzle gave at 2.0 kgf.cm-2 pressure corresponding to 300 mm nozzle height. The spraying
system was tested on soybean crop at forwarding speeds of 1.5, 2.0 and 2.5 km.h-1. With
an increase in forwarding speed, the mean percentage of coverage decreased significantly
(30.30 - 15.37 % for top and 20.01- 4.12 % for bottom part of the leaves), and the mean
droplet density varied significantly (277.35 - 243.40 no.cm-2 for top and 262.87 - 78.44
no.cm-2 for the bottom part of the leaves) at 5 % level of significance. A good percentage
of leaf area coverage (30.30 % and 20.01 % for top and bottom of the plant) was obtained
at low forward speed (1.5 km.h-1) while compromising more spray volume and less field
capacity as compared to higher forward travel speeds. The effect of forwarding travel
speed, position of tags and nozzle types were significant (p
