I have had the pleasure to conduct a variety of experiments, watch numerous management talks and take many classes on the scientific method. During these adventures I've noticed that people seem to misunderstand (or not comprehend the full power of) replication.
Replication is the repetition or duplication of an experiment. On the surface this seems pretty straightforward; why would someone want to replicate or duplicate an experiment? They do it to double-check that the results are correct.
If I want to test to see if hummingbirds prefer red or yellow feeders, I can put out two colored feeders and count the number of visits. Great! Right? Not exactly.

Alfalfa is an excellent competitor with weeds. There is no better weed control method than a dense stand of alfalfa. However, even with a good stand, some weeds can get a foothold and infest the crop reducing its marketability. Most growers have an effective program to control winter annual weeds with a dormant season herbicide application. When it comes to summer annual weeds, grasses, such as green and yellow foxtail and barnyardgrass (also called watergrass), have historically been the most troublesome. While these weeds continue to be a major issue, there also appears to be an increase in pigweeds (both redroot and Palmer amaranth) in many areas of the state including the Central Valley, Intermountain Region and High...
