A Method to Evaluate Seeder Performance

Evaluating in field seeder performance is challenging and sometimes requires destructive methods. An alternative method for evaluating seeder performance based on nonlinear regression was developed. This method yields parameters that describe seeder performance, such as emergence rate, initial emergence data, and emergence percent. These parameters are easy to explain to the practitioner. The proposed method was compared to a widely used method to assess emergence rate. Results assessing emergence percent were comparable between the two methods. There were differences between the emergence rate index and emergence rate determined from the proposed method. These differences were expected since the emergence rate index encompasses more information than simply the rate of emergence
