Growth, Yield and Water Productivity of Tomato as Influenced by Deficit Irrigation Water Management

Abstract The deficit irrigation offers water savings potential that is becoming popular in arid and semi-arid regions reducing freshwater use over time. A two-year factorial experiment was conducted to evaluate growth, yield productivity of tomato under the drip furrow method. carried out a split-plot design with as main plot treatments, soil moisture regimes (0, -10, -20, -30 kPa) subplots. Data were collected on growth parameters, physiological traits, tomato. results showed yield, significantly influenced by system regime. -10 kPa regime reduced total input 22.6% 19.8% gave 28% 22% higher fruit yields 2020 2021, respectively, compared system. Plant flowering occurred earlier (3 days) than irrigation. When content kPa, performed better for other improving phenological attributes, thereby, advancing yield. Thus, could reduce through precise irrigation, maximizing productivity.
