Trickle irrigation salinity patterns as influenced by irrigation levels and application rates

The four different treatments were: alternate day irrigation, 13% under, equal to, and 20% over the evapotranspiration and daily irrigation equal to evapotranspiration. The tomatoes were planted in eight lysimeters thus providing the replication of each irrigation treatment used. Two-dimensional contour patterns are reported for both the saturation extract conductivity and soil water potential of the soil profiles between two lines of emitters. Differences between irrigation treatments and recommendations are provided concerning the application of the results to the management of trickle irrigation systems.
