RE: Rye for a dove plot?
If you want to use it to attract doves - I think its important to mow it - to a stubble for the doves to get it. Cereal Grain is not as good as some other seeds like corn or sunflowers but would have some benefit it would seem
Also - when mowed in Late August - a good bit "sprouts Back" for another - (less vigorous) fall Rye plot.
