Abstract
The following irrigation treatments were tested on greenhouse tomatoes: improved furrow irrigation; microtube irrigation. ( 5 l/h ); drip irrigation (2 l/h ); subsurface irrigation.
Frequency and amount of water supplied were controlled by tensiometers, always maintaining the soil water potential at values higher than -0.02 MPa.
The total water depth applied during the September-June period for each treatment varied, mainly as a function of the watering depth of each treatment and were respectively: 46 cm for furrow irrigation, 36 for microtubes, 29 for drip and 26 cm for subsurface irrigation.
Frequency and amount of water supplied were controlled by tensiometers, always maintaining the soil water potential at values higher than -0.02 MPa.
The total water depth applied during the September-June period for each treatment varied, mainly as a function of the watering depth of each treatment and were respectively: 46 cm for furrow irrigation, 36 for microtubes, 29 for drip and 26 cm for subsurface irrigation.
No total yield differences were found among the systems tested; monthly yields were sometimes lower with subsurface irrigation.
The efficiency of applied water was higher with drip irrigation (47.7 kg/m3) and lower with furrows (27.8 kg/m3).
