Abstract:
This study was conducted at College of Engineering, Huazhong Agricultural University, China, 2019. It aimed to inspect theinfluence of two devices on seed precision performance of a multi-rows pneumatic disk metering device. Curved-edge and positive air blower were the two devices specifically used at four plate velocities coupled with their well-matching vacuum levels. Seed distribution of the two methods was also verified at 15 and 20 r/min incorporated with 1.2 and 1.4 kPa vacuum pressure, and 0.9 and 1.0 kPa positive pressure, respectively. Results exposed that vacuum amount utilized with mentioned speeds were adequate for attaining closer rows pick-up with consistency CV not surpassed 2.84%. The lowest quality index attained was 89.88%, while miss index not exceeded 7.1%, and rows stability CV was below 1.15%. Curved-edge device was found to be superior to air blower in quality index, miss index and rows stability. Study results concluded the appropriateness of the devices methods for precise seeding with a little variance, and more precise devices set up may generate better results.
