SS is perfect for that as they like it but lack the freebies obtained with a legume. You Alfalfa guys that responded, can you feed Alfalfa straight up in a roll, free choice....aka too hot?
Course, trin, you could sew both. I'm going to do that as soon as some rain is on the way here. Have Austrian Winter Peas and Jumbo Rye that I am going to drill for a spring crop.
On yield, I plant "Gotcha Plus" SS hybrid and I'd show you a picture of my 2014 crop where the field stayed wet longer than I wanted and it grew up over the cab in my tractor but no boots, no heads, small stems and super yield. Not sure I want to go the route available here for posting.
