Most farmers plant single strips of several hybrids and try to select hybrids for the following year. Single strips are OK for observations but replications can measure variability and give you more reliable results. Consider the following points for analyzing test plot data.
• One location or test is not enough to draw conclusions about the performance of a hybrid or variety but it is a lot better than not planting any test plot at all. However, when combined with information from other unbiased sources, your own test plots become a powerful tool for the selection process, especially when you start accumulating data for several years.
• For analyzing yield data whether from university trials, data from Seed Consultants test plots or third party data, make sure you are looking at data from replicated tests.
• Replications must be randomized which allows every hybrid or variety an equal chance of being on a certain piece of ground or next to a certain treatment as any other.… Continue readingRead More »
