Yellow flowered plant growing in my foodplot

Anyone know what this might be? In some of the plots it is 5-6 feet tall and in others it is only 1 foot to 18 inches tall. I am taking it out with the weed whacker but if it's something I want; I will stop...

Thanks for your help!

 

Probably, Sisymbrium officinale

 

Definitely Sisymbrium officinale.

 

Thank you so much! Is this something deer will eat or should I cut it back/out?

 

Should be OK for deer.

 

Thank you!

 

Or you could eat it ...

According to Wikipedia,
"This plant is widely cultivated across Europe for its edible leaves and seeds. It is widely used as a condiment in Northern Europe (particularly Denmark, Norway and Germany)."
