Technical Evaluation of Agriculture Drone Sprayer for Control of Wheat Weeds and Compare with Conventional Methods

In this study, the performance of the drone sprayer and conventional sprayers was evaluated for weed control in wheat fields. This project was conducted in a completely randomized experimental design with three replications. The studied parameters were: effective spraying width, spraying time per hectare and consequently the field capacity and field efficiency of sprayers, amount of herbicide solution per hectare, volume and number median Diameter of herbicide particles, spraying quality coefficient, drift, energy consumption, crushing rate of Wheat, sprayers effectiveness and economic evaluation. The results of analysis of variance showed a significant difference between the experimental treatments at 5% probability level. The results showed that the drone sprayer, boom sprayer and the turboliner sprayer had 11.14, 351.59, 249.14 liters solution per hectare, 16.76, 7.66 and 38.6% rate of drift, and 6.72, 5.92 and 7.66 hectar per hour field capacity, and energy consumption of 418, 2837.8 and 4796.2 kJ respectively. E was 72.6, 5.92 and 7.66 hectares per hour and energy consumption was 418, 2837.8 and 4796.2 Kjoules per hectar. Spray quality coefficient in drone sprayer and turboliner sprayer were 1.78 and 4.24, respectively. In 30 days after spraying, no significant difference was observed between treatments in terms of operation effectiveness. The cost per hectare of using drone sprayer was twice as much as conventional sprayers.
