Abstract(s)
Traditional edible, spicy and medicinal herbs rarely are included in studies on water requirements, evapotranspiration and
crop coefficients (Kc) of vegetable crops. While the latter refer to large markets and are used worldwide, the former has small
and specialized markets. They are very rarely grown in large farms but rather in small farming systems, or just harvested
in the wild, and related evapotranspiration (ET) studies are less frequently considered in main journals focused on water
management in agriculture. However, there is abundant bibliography covering traditional edible, spicy and medicinal herbs.
Following the partition adopted in recently published articles on K c values, such crops are grouped according to the main
part of the plant purposefully harvested: roots, rhizomes and tubers; leaves and flowers; fruits, pods and seeds. Since we
focused on Kc and not on the products, and because many crops have simultaneously two usages such as spicy and medicinal,
main uses are presented to characterize the crop. Interestingly, the reviewed crop coefficients have values quite similar to
those of the more common and popular vegetable crops. The single crop coefficients reviewed, and referring to the initial,
mid-season and end-season periods, are tabulated according to the referred groups. In addition, aiming at their use in water
management and modelling, crop heights, root depths, fractions of ground cover and fractions of soil water extraction without
stress are also tabulated. In conclusion, this review aimed at successfully provide K c values to be used for computing crop
evapotranspiration for irrigation scheduling and crop water management of the referred herbs and vegetables.
