This mod expands the basic set of farming-related crops that minetest_game offers. It adds melons, potatoes, tomatoes, green beans and corn. The mod also implements plant humidity - you will have to water plants to make sure they're not dried out, or make sure they don't get over-watered.
Mod specific settings can be changed in the "crops_settings.txt" file in the world folder.
