Özet
This study was conducted to determine the effects of nitrogen (N) doses on yield, quality, and nutrient content in broccoli heads. Treatments consisted of 0, 150, 300, 450, and 600 kg N ha(-1). Nitrogen rates significantly increased yield, average weight of main and secondary heads, and the diameter in broccoli compared to control. The highest total yield (34631 kg ha(-1)) was obtained at 300 kg N ha(-1). At harvest, the highest amount of the total N in broccoli heads was measured at 450 kg N ha(-1) application. Potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), and zinc (Zn) content increased with increases in nitrogen treatments but, phosphorus (P), copper (Cu), manganese (Mn), boron (B), and sodium (Na) contents were not influenced. Also, removed nutrients by broccoli head were highest at 300 kg ha(-1) N rate.
