I'm in the same boat. I don't have as much plantable acreage as needed, so I have to get as much productivity as possible from my plots. I think some of our techniques are the same or close. Some of the things I have found that help the most are:
1) Using RR crops for warm season annuals. This make a huge difference in yield for me.
2) Surface broadcasting into standing beans. In my case, except for 1 acre protected by and e-fence, I have never been able to get beans to canopy with my deer densities. I'm using Eagle forage beans which survive the heavy browsing, but the deer keep them from forming a canopy. They are very late maturing, so if they did canopy, I would not likely be able to surface broadcast a cover crop. However, if I get enough planted that they get ahead of my deer densities so they do canopy, I can start mixing in ag beans. I'll be working on getting the right mix over the next few years using my e-fence as an experiment. I want enough late maturing beans (which don't start to yellow until mid Oct here) to be an archery season attraction, but enough ag beans so I can surface broadcast in September.
3) I put a durana clover base in all of my small hunting plots. Using a no-till drill when the clover goes dormant, I use a no-till drill to add radish and cereal. This helps use up N keeping the field in production longer while adding to the attractiveness in the fall.
what brand and model of no till are you using. roundup ready has brought us out of the dark ages but many weeds are developing immunity. in the old days i would have to use different chemicals for the corn and the beans and the allis chalmers no till drill never did work. it would plant for a while and then miss for a while. if your chemical was applied ones options was limited. the angles were singing when roundup ready appeared. i have found that i can do without a drill by broadcasting the seed but it does take more seed.
i am in a area where there is plenty of real farmers planting crops so the pressure on my summer beans will not be extreme. i try to have non seeding beans late in the year which since i can not afford 100 dollar a bushell eagle forage beans has to be supplied by either a late july planting or adding them in my winter mixes. the last beans of the year that are still green will be found and will be hammered. doing this is a gamble a few years ago the first freeze was septeber 15. i think the average is around the 5 th of oct in my area. if this works out you do have a very good early attraction as well as another double source of nitrogen. again with a full bag of tricks one hopes to be nimble enough to adjust to what mother nature throws his way. failure is not a option. i finally completed this winters timber stand improvement today i will have to take some pictures of the mess. as well as other areas that have been done at different times as they respond. beauty is in the eye of the beholder. one has to keep focused on the long term goal and keep hammering away. i have found that if you are getting to much early pressure on your beans, turkey can wipe them out as soon as they sprout, throw some oats in the mix. the critters will hammer the oats giving your beans a chance to get their roots established. truly hazelvillebucks
