| I'll listen if you tell me that you have an advanced degree in statistics. Acutally, long strip trials work because they average the spatial variation that exists in any field. The longer the strip, the better. Replicated strips also enhance the power because it minimizes the opportunity for the tester to select the best strip. The best design is a full field of replicated full length strips with each strip being a combine header width. With GPS guidance, fast and easty to do and analyze. Will make your neighbors stare if you harvest based on moisture content - but worth it. This system lets you figure out the best variety for different cropping situation (valleys, hillsides, wet spots, etc.) | |
