OK, In the tomatoe department. There are 2 kinds of tomatoes - Determinant and Indeterminant. One branches and one doesn't.
Determinant usually have mostly one big crop, are usually shorter season and do not branch very much. Smaller bushes. Like Roma Tomatoes
Indetermant are longer season, usually like beef steak. They branch so if you want some early tomatoes you can pinch the branches so they put their energy into fruit instead of vine. If you live in a longer season climate or hot weather climate you leave these branches on for more shade for the plant and longer season tomatoe production.
I seem to remember reading about years ago that in cooler climates you can pinch branches off melons, squash and cucumber to do the same, encourage an early fruit production, but I am not sure.
