Abstract :

Infiltration and water application efficiency are important parameters in the design and evaluation of irrigation systems, which are affected by agronomic management such as tillage practices. Present study was conducted with the main objective of investigation of tillage methods effects on cumulative infiltration and water application efficiency in a wheat farm at the E. Azarbaijan Research Center for Agricultural and Natural Resources ( Khosroshahr ). The experiment treatments were no-tillage, tillage by chisel plow and disc, low tillage and tillage with moldboard plow with disc. Soil infiltration was measured by the ring and water application efficiency determined for studying conditions. Results showed that tillage methods produced different cumulative infiltrations. The cumulative infiltration from low tillage, no-tillage and tillage with moldboard plow were 62, 20 and 10% of cumulative infiltration from chisel plow. Water application efficiencies from chisel plow tillage were less than 55% and efficiencies from no-tillage by moldboard plow were 55% and 68% respectively.
