At the Abadszalok (Hungary) melioration model site, at meadow and meadow-alluvium soils under the hydrological influence of Tisza Lake, the effects of the various ameliorative operations on the yields can be summarized as follows: With the application of a 25 m spacing drainage system in an 8 year average 0.5-0.6 ton/hectare corn unit yield increases were obtained. A significant increase in yield relative to control required draining off the water from the tubes. At dry condition drainage did not have a yield increasing effect. By the effect of subsoil irrigation through drainage there was no yield increase at sunflower however, 0,5 CU yield increase was found in maize as a three years' average.
