Your idea is sound, but you seem to have your timing off.
You plant your winter rye or oats in conjunction with your corn so that your cover crop acts as a weed barrier for the corn. Then you harvest your corn. A lot of farmers who plant corn, conventional and organic, do so this way now. I am not exactly sure though how you will incorporate your green manure cover crop without incorporating (tilling) it though? Nitrogen is easily, and readily lost.
But you could also plant your winter rye in the fall, let it go dormant over the winter, and wait for a crop in the spring. By harvesting that, and then immediately planting short day corn, you could get two crops off the same field in the same year...even here in short-growing season Maine where I live.
But the last two paragraphs are rather different things. The first is for weed control and green manure, while the second paragraph is so a farmer can get two crops.
But the second paragraph would also work for people with livestock. They could harvest their corn for winter feed in the fall, then plant winter rye. By the time the regular pastures start to decline from the cold, the farmer could get a few extra weeks of grazing in. Then pull the livestock for the heart of winter, but return them for a few weeks of early grazing in the spring when the other pastures are not yet greened up. The real question is, is the cost of the seed and fuel to put it down worth it? It could be, depending on how much hay, and how expensive it is for the farmer to buy. But this would greatly extend the grazing season.
This is a nice field of oats I planted two years ago for the sole purpose of weed control in a freshly planted field.
