This research investigated the effects of the tillage and nitrogen doses on water use efficiency, soil moisture, seed yield and seed oil content in wheat-safflower rotation under Ankara conditions during 1996-1997. The experiment was established as split plots in randomized blocks with three replications. Tillage methods (zero tillage and conventional tillage) and nitrogen doses (0, 4, 8 and 12 kg N/da) were placed in main plots and sub-main plots, respectively. Safflower was planted directly to stubble after wheat harvest using zero tillage method. For tillage soil was cultivated with plough, cultivator and harrow, respectively. Yenice 5-38 and ammonium sulphate (21% N) were used as material and nitrogen source. The safflower sown in autumn was grown in dry conditions. According to the research results; the water use efficiency varied, for the conventional and zero tillage, between 0.24-0.26 kg/da/mm and 0.19-0.27 kg/da/mm during first year, and between 0.27-0.36 kg/da/mm and 0.18-0.25 kg/da/mm during second year. Soil moisture content increased with soil cultivation under each fertilizing. Seed yield in zero tillage reduced by 22.33-38.91%. Both tillage methods and nitrogen doses did not affect seed oil content.
