In my area it's just called the "second cutting".
Rowen
The second cut, or cutting. In New England, the second crop is called a rowen.
At the first harvest, they pick whatever fruits or vegetables are at the appropriate point of ripeness. It depends on the crop. With a crop like hay, when the hay is at the appropriate height, they run the machine through it, cut it, and bale it. With cotton, they pick the bowls when they at a little over 2 inches. Then the second crop grows. With peaches, they pick the first crop so the second can grow.
Rowen
In 2009, according to the USDA, the state of Oregon had more acres of hay than of any other single crop. Hay was over a million acres and the second largest acreage, 890,000 acres, was of wheat.
Not directly. But many farmers interseed (plant amongst) a hay crop along with a grass crop like wheat or oats. The grass cover crop helps protect the hay crop while it is very young and prone to damage. When the grass crop is mature enough, the farmer harvests it and leaves the hay crop to grow on its own.

well generally a feed store will provide hay for you to buy, but if you mean where does it grow, then its generally a crop that can be grown/ found on a farm.
The number one cash crop in Tennessee right now is Marijuana. After that is Soybean and Hay.
The most important crop is hay to feed the cattle and horses. Another important crop is maple for maple syrup.
