If I read your link right,
Winter wheat, he said, fits well when rotated with summer crops, such as dry beans.
means the recommendation is to follow winter wheat with beans. So you need to look at it as rotation over SEVERAL years.
Let's say you planted half your garden with winter wheat this fall. You would harvest that late July/Aug -- in other words, about now next summer -- then sow beans for growing in that space rest of the season. Note that technically, you would sow the beans a few days before or as
you harvest, BETWEEN where the wheat plants used to grow. But maybe it doesn't have to be dry beans, maybe you could grow an early variety of snow peas.
OK, leaving them to grow, let's get back to the other half of your garden -- WHAT do you WANT to grow there next year? Let's say you want to grow tomatoes. You need the bed available by beginning of June... Is there cool weather crop that will come out by then? Lettuce and spinach may be? You could sow those a month before last frost. if that's what you want to do, go with winter cover crop that winter kills, like oats and less hardy clover like crimson. Or you could try planting winter mustard or arugula in the fall. I find Dinosaur Kale to be pretty hardy too. You could also plant garlic.
See how you have to plan BACKWARDS?
Now let's go back to next fall after you've harvested the beans... Well, that might be the time to plant garlic in this bed. You could have also sown clover or maybe lettuce and other fall crop under the beans. After winter is over, you could sow the early spring-sown grain like oats here or maybe peas. OR you could undersow the beans with winter killing cover crop and plan to plant tomatoes HERE next year.
It's getting too complicated but I think you get the idea. If you have the space, it's a good idea to have 4 areas to rotate around.
