The weekend of July 4th we planted some food plots on my property in north missouri. we did a combination of ladino clover, turnips, rape, and rye.... the first picture is after about 3 weeks, the plots are looking great.... after a couple more weeks, they are still not too bad, starting to get some weeds but by September, they were completely over run with these tall yellow flowery looking weeds. You can see some of them on the right side of the 2nd picture? What is this? I assume a weed but just wondering where I went wrong.

One of the farmers told me to cut the plots (cut high, like 12-18") which I did a couple weeks ago but wondering if I just trashed my plots? the clover seems to be doing good, just wondering why I am so over run with these yellow flowers now... we did spray a week or two before we tilled and planted. Any advice or feedback? Thanks!
