Lancaster, OH | If you do it, split the planter and do a large area and harvest each section. There is so much field variation in disease pressures, stand, stresses, etc. that a single side-by-side really tells nothing. As a matter of fact, the typical testing method of randomly replicated blocks that are 2-4 rows wide and 12-24' long are often so isolated that those environmental pressures don't show well.
Larger areas, more replications. Remember, we're looking for differences that involve 2-10 different living organisms (plant, different diseases) that thrive in similar but separate environments so predicting specific results for one test is near impossible. It is far different than comparing 2 different varieties of the same plant or two different chemicals for control of a particular weed. Many more moving parts. | |
