Running a fertiliser rate trial

The first step in the 10 point plan is *
When writing down what you want to learn from your trial, you should *
It is better to get a trial underway than fluff about worrying about the measurements you will make *
Head-to-head trials are good because you get a simple A-B, old-new comparison that you can put into action *
A good rule of thumb for fertiliser rate trials is to use rates that differ by *
When changing the fertiliser rate in a trial, you should also change the population to keep things the same *
A general soil fertility test is an essential part of a nitrogen fertiliser rate trial *
Trial measurements should be made *
Quantitative measurements that give actual numbers which can be used for ANOVA statistics are known as *
The purpose of replication is to *
Replication is like a sports competition where each team meets each other team for several matches. *
Using five, rather than four, replicates will give 25% more work but only 15% more precision *
When setting out a trial, arrange treatments that place blocks along the soil variation and then arrange plots across the variation. *
If space is limited, it is better to have larger plots than more replicates *
Harvest widths should be narrower than plot widths *
If doing a nitrogen rate trial on a tight budget, it is a good idea to *
In general, soil fertility tests should be done *
If equipment has calibrated, you can be sure the right rate was applied to your trial *
If you see interesting or unusual differences in your treatments, you should try to get objective measurements *
When harvesting a fertilier rate trial, you should AVOID collecting samples (pick 3) *
You must measure the length and width of the area you harvest, as well as the weight of material harvested *
If you find data is missing, you can replace up to 25% with average values from the remaining plots in the same treatment *
