What characterises herbaceous crops and woody crops?
Herbaceous crops are non-woody plants like most vegetables and grains, while woody crops include trees and shrubs such as orchard fruits and nuts. Herbaceous crops exhibit rapid growth and tenderness, making them suitable for consumption, while woody crops provide long-term production and structural support.
