Yield, Physiology, Fruit Quality and Water Footprint in Persian Lime (Citrus latifolia Tan.) in Response to Soil Moisture Tension in Two Phenological Stages in Campeche, México

Sixteen irrigation treatments were applied on Persian lime, based the combination of four soil moisture tensions (SMTs) used to define start irrigation: −10, −35, −60, and −85 kPa during phenological stages (PSs) flowering (FL) fruiting (FR). Variables evaluated were, among others: leaf water potential (Ψ), stomatal conductance (gs), fruit weight (FW), juice content (FJC), total soluble solids in (TSS), yield (FY), footprint (WF). Greater values Ψ gs variables observed plants subjected SMTs −10 −35 (p < 0.05). The SMT FR produced a low FW value, while lower this PS increased it FY was greater including or either two PSs, with exception those one Lower FJC obtained at FR, higher TSS driest smallest WF −60 FL treatment ≤ Irrigation management significantly affected almost all response evaluated. It is recommended irrigate crop which greatest FW, FY, lowest 0.05) only 93 L by trees produce kilogram (16% amount largest WF). use blue limited its scarcity high opportunity cost, an aspect that can be mitigated if efficiently lime production systems, results study.
