| dc.description.abstract | A tractor operated trailed type boom prayer was selected to evaluate its performance under local agro-climatic conditions. To select suitable operational parameters of the sprayer, the sprayer was initially tested under laboratory conditions. Under laboratory conditions, it was observed that the nozzles spaced at 50 cm apart on the boom gave comparatively uniform spray distribution when the sprayer was operated at higher pressure keeping nozzle height 55-60 cm above the target surface. The droplet density varied from 29 to 174 drops/cm2.The area covered by droplet spots on the leaves under laboratory conditions varied from 9.10 to 25.06 mm2/cm2 and volume of spray deposition on upper side of leaves varied from 194.11 to 626.23 ×10-6 cc/cm2. The sprayer was operated in the cotton field at three forward speeds (2.5, 3.5 and 4 km/h) and at five fluid flow pressures (3.5, 4.0, 5.0, 6.0 and 7.0 kg/cm2)for its performance evaluation. The droplet density on leaves varied from 26 to 177 drops/cm2.Area covered by droplet spots on upper side of the top leaves, middle leaves and bottom leaves varied from 14.18 to 24.70 mm2/cm2, 11.01 to 23.07 mm2/cm2 and 8.74 to 17.22 mm2/cm2 respectively. Volume of spray deposition on upper side of the top leaves, middle leaves and bottom leaves varied from 330.19 to 677.87 × 10-6 cc/cm2, 293.27 to 633.99 × 10-6 cc/cm2 and 202.71 to 685.57 × 10-6 cc/cm2 respectively. | en_US |
