Design and Performance of Subsurface Irrigation Using Porous Emitters for Tomato (Solanum Lycopersicum, L.)

This study aimed to design and implement a subsurface irrigation system using porous emitters of various materials such as bubblegum, flannel, cotton, spandex. It was carried out descriptive methods, namely designing, measuring, observing, calculating, analyzing data quantitatively. The results showed that the soil conductivity ranges from 1.0 3.01 cm3/hour, flannel material transmitter has maximum hydraulic 4.681 cm/hour. largest smallest discharges were found in bubblegum materials, with values 2.4 l/hour 0.59 l/hour, respectively. Emitter had best absorption capacity 1.9348 growth emitter plants highest 228.6 cm, 158, 133, 92 for height, leaves, flowers, fruit. daily water requirement vegetative phase 112.15 ml/day, flowering stage continued increase by 211.95 while fruiting 176.63 ml/day. Tomato decreased 156.96 ml/day at ripening stage, application one day after vegetative, flowering, fruiting, stages required 118.33 141.30 194.28 ml /day, 264.93 mm/day, Furthermore, produced optimally meet needs plant growth, no surface runoff loss due percolation, efficient use water, can reduce or prevent salinization.
