With heightened interest among growers in using variable-rate application (VRA) to reduce input costs, it is recommended they first conduct on-farm trials to generate paddock data... "While data collected from farmer trials using yield mapping software will never be as accurate as small plot trials conducted by researchers, they are a simple and efficient way of gathering information about variation within paddocks," he said... "One way of being confident about yield differences observed in strip trials is to keep them simple: stick to one or two treatment differences and make the size difference between treatment rates large...
