CropBuddy

CropBuddy is a very light weight and easy to use plugin that enchances your minecraft farming experience!

Prevent Crops from being trampled by players or mobs
Allow right click harvesting of crops with auto-replaning of the seeds using either just your hand or with a hoe of choice (Fortune ecnhants work with the Hoe auto-planting!)
Adjust drop values of crops and seeds.
Make changes on the fly with the /cropreload command to reload the config file without having to restart your server.
