Agro Ecological Zones
Kale is grown in a wide range of climatic conditions provided water is available.
Altitude
The crop performs best at altitudes 800-2,200m above sea level.
Temperature
The optimum temperature range is 17 - 22°c.
Rainfall
Kales require adequate amount of water throughout its growing time. Rainfall amount of 350-500mm which is well distributed is ideal for optimum yield.
Soils
Well drained soils relatively high in organic matter content are suitable for production. The soil pH should be 5.5.-7.0. If the ph is too high; manganese is frequently unavailable which results in yellowing (chlorotic conditions) of leaves.
