Every area is different depending on what food is available and what they are used to eating. My buddy planted turnips and beets 2 years ago and they grew awesome for our area but the deer didn't touch them. Last year he planted the same crop and around this time of year he partially dug up 50 or so of each in random spots in that plot and the deer hammered them in November. This spring we walked around that plot and couldn't find any turnips or beets, so it just took the deer some time for the deer to realize what they are and how to get to them.
I was sold on Pears about 10 years ago, I was building a deck with a friend at a house that had 100 yard long back yard maybe 40 yards wide with just one tree in the middle of the yard. The edges were lined with several different oaks that were dropping, some butternut, red apples and 2 cherry trees as well as a lot of landscape type bushes. Ninebark, Forsythia and Dogwood are the only ones I recognized. The tree in the middle had to be 50-60' tall and dropped small yellow/green apples. When one apple fell it would bump others and 10 or so would hit the ground. There were a few doe with their fawns that consistently bedded under the pines at the far end of the lawn that would get up, walk past all the oaks and other goodies along the way and clean up the small apples first, then eat a little of everything else on their way back to their beds. After the 2nd day of watching this I walked over and took a bite of the small apples and much to my surprise, it was a pear. It was as close to a dinner bell to the deer as I have ever seen in person. I am sure the attraction is different from each area so I am sure this isn't the case across America but here in NY.... wow
