A small tractor operated boom type sprayer was selected to evaluate its performance under local agroclimatic conditions. The nozzles were spaced at 50 cm apart on the boom and operated in the field at nozzle height of 55 cm above the target surface. The sprayer was operated in the Guar field at three forward speeds (3.0, 3.5 and 4 km/h) and at three fluid flow pressures (2.0, 3.0 and 4.0 kg/cm 2 ). The droplet density on leaves varied from 8.86 to 155.46 drops/cm 2 . An Area covered with droplets on the upper side of the top leaves and bottom leaves varied from 8.4 to 70.55 mm 2 /cm 2 and 2.85 to 66.4 mm 2 /cm 2 respectively. An Area covered with droplets on the underside of the top leaves and bottom leaves varied from 1.83 to 40.48 mm 2 /cm 2 and 2.21 to 30.91 mm 2 /cm 2 respectively. The volume of spray deposition on the upper side of the top leaves and bottom leaves varied from 82.5 to 1201.53 × 10 -6 cc/cm 2 and 41.74 to 958.73 × 10 -6 cc/cm 2 respectively. The volume of spray deposition on the underside of the top leaves and bottom leaves varied from 22.63 to 601.62 × 10 -6 cc/cm 2 and 21.89 to 9418.4 × 10 -6 cc/cm 2 respectively. RSF varied from 0.46 to 1.22 and 1.37 to 3.77 for volume basis and number basis, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
