2.  How many environments (years and/or locations), for a specific experiment, does your project  usually collect before submitting the results for publication.

(2, 4, 6, 8, 10, >10)

5,4,2,6,10,6,6,6,2,4,8
(e.g, an experiment conducted at 5 locations over 2 years would be 10 environments)

3.  Before putting out your field experiments do you soil sample each experimental unit (e.g., all 15 plots (3 reps, 5 treatments))?

(yes     no  )

 no, no,yes

4.  Have you ever used a covariate in analysis of variance?  ( yes       no  )

no,no,no

5.  If you put out four of the above experiments (5 treatments, 3 reps) at different locations, and you found from the combined analysis that the treatment*environment interaction was significant, what would you do?  (or how would you partition this effect?)

a. Don't know

b. Discuss Environments (locations) independently
