Growing by bonfil-Fukuoka method when to plant various grains

hi,

it is spring here in New Zealand, and we are trying again to contain our pigs in a movable structure in order to have them dig up our patch to plant animal food (grains, root fodders etc.)

I have read in detail this article on growing wheat, as well as some others I can't source:

From what I read, you plant the winter wheat as soon as possible after mid-summer when the days start shortening again. It seems you also only need 4 plants per square metre.

What about the other grains? I also have some barley, oats and rye that I was sold as suitable for winter planting but did not get planted out last autumn. Do you plant them at the same time and the same distance apart?

I am also asking a question about growing temporary beds this style in another topic.

"The main danger lies in the wrong choice of variety: if a strictly winter variety is not used, then the plants will go to grain before winter, producing less than the standard methods. Most modern varieties, being hybrids between winter and spring or warm-climate types, have this tendency. Therefore, one should seek long-straw, traditional varieties, with strong vegetative vigour that gives plenty of side-shoots and dense foliage." - http://www.agriculturesnetwork.org/magazines/global/monocultures-towards-sustainability/how-to-grow-winter-wheat-the-fukuoka-bonfils

My impression is that they use varieties that take up to a year to mature and the next crop is planted as the previous one is harvested. Maybe there are variants on it, I dunno. So I don't think most of the other grains would work in this system, though maybe rye would.
