 Irrigation water saving strategies in Citrus orchards: Analysis of the combined effects of timing and severity of soil water deficitÀngela Puig-Sirera, Giuseppe Provenzano, Pablo González-Altozano, Diego S. Intrigliolo and Giovanni Rallo Agricultural Water Management, 2021, vol. 248, issue C Abstract: The knowledge of the crop response to soil water deficit is essential to predict the actual crop water requirements under limited soil water conditions. The mathematical schematization of the crop response under RDI can allow identifying the exact irrigation timing. The threshold of soil water status below which crop transpiration decreases represents a key parameter for the water stress functions. The main objective of this paper was to investigate the effects of several RDI treatments, applied during the three stages of fruit growth, on soil-plant-water relations of drip-irrigated mandarin trees. Experiments were carried out in seven irrigation treatments: a control, irrigated at 125% of potential evapotranspiration measured in weighting lysimeters, ETlys, during the whole year, and six RDI treatments in which 25% and 50% of ETlys were applied during each of the three stages of fruit growth.
