Optimizing the yield of cultivated desert truffles

Producing desert truffles constitutes a valuable agricultural activity in semiarid areas of the Iberian Peninsula due to their much appreciated edible value and their low water requirement. Scientists Andrino et al. found that the crop of desert truffle can be stabilized and optimized, around 300 kg/ha, by controlling the aridity index and soil water potential in the field by irrigation during autumn and spring. They propose four methods to manage the plantations depending on available resources and facilities at the cultivation sites.
