Abstract: In order to evaluate potato respone to drip irrigation and N fertigation; and also to improve nitrogen and water use efficiencies of potato and eventually to obtain less nitrogen polluted surface and ground water, 10 field experiments were carried out at three different locations in Cappodocia Region of Turkey in 1997, 1998, 1999 and 2000. Nitrogen as ammonium sulphate [(NH4)2So4], was supplied through drip irrigation water (fertigation) at rates of 0, 30, 60, and 90 kg N/da. Also, soil N application treatment equivalent to the fertigation treatment of 60 kg N/da was included. These five treatments were investigated in a completely randomized block design with four replications. Agria potato variety was used in all experiments and potato was planted in mid May and harvested at the end of October. 15N-labelled ammominum sulphate fertilizer were applied in isotope-sub plots within the macroplots for each treatment in order to determine the amount of nitrogen taken up by the plant, nitrogen use efficiency and the distrubution of residual nitrogen at different depths in the soil profile. Each year during the growth period 12 irrigations were done and 50 mm of water was applied at each irrigation. At harvest, plant samples (tuber and leaf+vein) and soil samples were taken and % N, % 15N atom excess (% 15N a.e.) and % Ndff determinations were done. Soil water contents at different soil depths were determined by soil moisture neutron probe at planting and at harvest so that water contents at different soil layers and water use efficiencies were calculated for each treatment. The results obtained showed that 3350 kg/da mean total marketable tuber yield was obtained with application of 600 mm irrigation water. Also, it was found that water did not move below 90 cm of soil layer in drip irrigationfertigation system, which showed clearly that no nitrogen movement occurred beyond 90 cm soil depth. Tuber yields and % Ndff increased when nitrogen is applied with drip irrigation-fertigation system in comparision to the application to the soil and then drip irrigation. At harvest, more nitrogen was accumulated at shallower depths with fertigation treatments.
