A major environmental concern in agriculture is the use of fresh water for irrigation.
Water resources are under threat due to the increase in water demand for agriculture, and the gap between water availability and demand is exacerbated by global climate changes.
Afzal, M., et al. (2016). Agric. Water Manage. 176, 40-54.
Tomato crop is highly concerned with this issue. In Italy, the blue water footprint (ratio of the volume of irrigation to the crop yield) of this production has been estimated at 60 m3 per ton.

Irrigation was scheduled daily to compensate the evapotranspiration loss from tomato crop (ETP). Water was first supplied every day in order to fully fit 100% of ETP. Forty-five days after sowing, two levels of irrigation were applied: (1) water deficit (60% replacement of ETP in 2016; 50% replacement of ETP in 2017) and (2) well-watered to match 100% replacement of ETP.Fruits were harvested at 40 (light orange), 47 (orange red) and 55 (red ripe) days after anthesis (DAA) for quality analyses and processing.Representation of the two irrigation regimes

Conclusion and PerspectivesAlexandre VILAS BOAS/
Tomato fruit quality and processing ability are impacted by irrigation regime as well as genotype and maturity stage.15
th ISHS Symposium on the Processing Tomato, June 11th - 15th, 2018, Greece
A reduction of water supply from 100% to 60% of the ETP, increased the water use efficiency by 20% and may enhanced the dry yield depending on genotype.WD modified the reactivity of tomato fruits to process.
the activity of pectin-degrading enzymes in response to WD should be analyzed in further details for a better understanding of the WD effect.Fruit Brix is not a good indicator of puree viscosity. Pectin composition and solid particle size and shape should be investigated in further details.
