For this plant (although resistant to drought) irrigations are necessary above all to obtain good yields and good size, the cadence of the irrigation shift must be determined relatively to the structure of the ground. It is interesting its good tolerance to a relative salinity of irrigation water. For maintenance fertilization, it is necessary to opt for additions between green manure with leguminous plants and the addition of well-mature manure or compost, depending on the type of soil or the integration with green manure.
