When developing agricultural sprayers, it is desirable to follow measures and procedures that would result in minimal impacts on the ecosystem. With the technical perfection of the machine for plant protection, it is especially important to adjust the technical parameters of application of pesticides -working speed, working pressure, air flow and speed, spraying norm, type of sprayer, etc.The aim of the research is to define the jet geometry in accordance with the average canopy geometry, with the task of increasing the efficiency of the application by adjusting the parameters to the treatment conditions. The result is a reduction in the risk of environmental impact, through a reduction in losses.The norm of 530 l/ha, achieved a slightly higher coverage on the target area of 56.27% on the left side, while the right side is slightly less covered with 46.08% coverage. The highest norm in the research was 650 l/ha with an average coverage of 56.28%, ie a coverage of 64.48% on the left side and 48.09% on the right side of the unit.

“…This drift commonly causes a hazard to both human and animal health as well as a source of environmental contamination (Maski and Durairaj 2010). A tractor-based spray application system can be promoted to reduce the multiple -input and achieve uniform deposition, distribution, and vertical fluid distribution (Sedlar et al, 2013). As a result, it's important to encourage the usage of timesaving machinery operated by tractors (Raut et al, 2013).…”

Chilli (Capsicum annuum L.) is an important vegetable and spice crop belongs to Solanaceae family which grown all over the world. Dried pods contain 36 gms of carbohydrates, 18 gms of proteins, and excellent source of vitamin A and vitamin C which together provide roughly 160 calories of energy per 100 gms (Narayanan et al., 1999). Area, production and productivity of Chilli in India was 7.43 Lakh ha, 19.14 Lakh Tonnes and 2576 kg/ha, respectively (Anonymous, 2018). Keeping in mind, above parameters the performance of tractor operated boom sprayer was tested on Chilly crop. Under laboratory conditions, the designed boom sprayer performed excellently at 0.90 l/min nozzle discharge and 689.5 kPa operating pressure. It was observed that droplet size, spray uniformity, and droplet density was influenced by the nozzle discharge rate and pressure of 0.45, 0.70, 0.90, and 1.35 l/min and 275.8, 413.7, 551.6, and 689.5 kPa, respectively. The Volume Median Daimater (VMD), Uniformity Coefficient (UC) and Droplet Density (DD) of the existing boom sprayer have 130.9-206.36 µm, 0.98-1.39 and 11-27 number of droplets/cm2, respectively, for nozzle 0.9 lpm and pressure 689.5 kPa. The modified sprayer has droplet sizes between 125.04 and 181.42 m, droplet densities between 16 and 27 number of droplets/cm2, and uniformity coefficients between 0.99 and 1.25 at nozzle discharges of 0.90 l/min. With the 689.5 kPa working pressure and 0.90 l/min nozzle discharge, the designed boom sprayer offers notably higher discharge and nozzle pressure in each individual nozzle than the existing sprayer.
