The present study was carried out through Large Scale Demonstrations (250 no.s) of Kisan Drone in an area of 625 acres and implemented successively in the operational area of ICAR- KrishiVigyan Kendra, Kampasagar, Nalgnoda district (Telangana state) under Agricultural Drone Project, financed by ICAR, ATARI during the year 2022-23 to appraise the effect of Drone utilization for spraying of Agricultural chemicals. In this study, Conducted 250 demonstrations on spraying of insecticides, fungicides, post emergence weedicides, and Nutrients in 625 acres, majority of the demonstrations were carried out on Pest management in 530acres (212 demonstrations) other weed management and Nutrient management sprays were covered in 95 acres (38 demonstrations) in paddy crop. In Farmers practice, spraying was done with manual operated power sprayers. From this study, it was concluded that, there is a vast scope for drones in agricultural applications. Drones will be able to spray more land in less time. This will save the time of farmers i.e., 16 minutes/acre in demonstration field, as compared to 84 minutes/acre in farmers’ practice. The cost of spraying was reduced to an extent of Rs 150/acre as compared farmers’ practice, hence resulting in financial savings of the farmers. There was 13 per cent yield increase in demonstrated plot over farmers plot because of timely sprayings. About 72% of the pest population was reduced in demonstration field and farmers were satisfied with this technology. There is a need to further disseminate the improved technologies among the farmers with effective extension methods like training and demonstrations. Farmers’- should be encouraged to adopt the technology for realizing higher returns. Horizontal spread of improved technologies may be achieved by successful implementation of demonstrations and various extensions activities like Training Programmes, Awareness Programmes, field days etc. organized in the farmers’ fields. Farmers have shown keen interest to adopt this technology in large area in the ensuing seasons.
