Abstract

This study was conducted to determine the effect of different nitrogen and phosphorus doses on yield and yield parameters of safflower. Experiment designed in split plots of randomized complete blocks with three replications. The treatments consisted of four nitrogen doses 0, 4, 8, 12 kg N/da as the main plots and four phosphorus doses (0, 4, 8, 12 kg P2O5/da) as the subplots. According to the results, nitrogen and phosphorus doses change has positive effects on day of rosette stage, flowering date, day of maturity, plant height, number of side branches, number of table, weight per thousand seeds and seed yield. It was determined that, plant height, number of branches, head number, head diameter, 1000 seed weight, hull-kernell ratio, yield, and crude oil rate ranged from 48.5 -54.5 cm, 2.6-3.6, 3.6-4.7, 19.73-22.28 mm, 34.79-37.43 g, 57.06%-59.37%, 82.17-182.23 kg/da, and 35.35%-38.59% respectively. The highest yield was determined as 182.23 kg/da from 12kg N/da+12 kg P2O5/da fertilizer doses.
