Effect of Nozzle Height on Spray Overlapping of JNKVV Push Type Solar and Battery Operated Sprayer

Study was conducted at the Department of Farm Machinery and Power Engineering workshop, College of Agricultural Engineering, JNKVV, Jabalpur, Madhya Pradesh to determine the nozzle spacing and boom height of JNKVV push type solar and battery operated sprayer on the basis of width of overlapping of spraying. It is difficult to obtain the consistent width of the overlapping between adjacent nozzles for the commonly used spraying. Coefficient of variation of nozzles overlapping varies according to the spray height and nozzle spacing. Precision guidance and precision sprayer control have substantial promise to reduce input application overlap, thus saving chemicals, fuel, and time during the application process. It was found that the overlapping increases with increase in height of the boom. The results were obtained by the overlapping test for boom height and nozzle spacing, there was no overlapping obtained up to height of 80 cm. The overlapping varied from 39 cm to 43 cm and mean overlapping was 41.3 cm at nozzle height 120 cm and nozzle spacing of 60 cm. An average overlapping of nozzles varies from 29 cm to 34 cm at nozzle spacing of 70 cm and boom height of 120 cm. At the boom height of 160 cm and nozzle space of 70 cm, spray overlap fluctuates from 79 to 85 cm. The overlapping at nozzle space 80 cm varies from 19 to 22 cm and mean overlapping was 22 cm at the boom height of 120 cm and nozzle space 80 cm. The overlapping varies from 70 cm to 74 cm in nozzle series at the boom height of 160 cm and nozzle space 80 cm. As per the crop cultivation practices, adjusted the boom height and spacing to reduce overlapping of spraying.
