Effects of sowing dates and nitrogen application on phosphorus and potassium contents in parsley

The effects of increased N rates (0, 100, 200 and 300 kg N ha(-1)) on yield, plant length, number of stalk, phosphorus and potassium content in parsley leaf and stalk during seven harvesting at two sowing time were investigated. Nitrogen rates and harvesting times had a significant effect on this criterias. The highest yield, plant length, number of stalk were observed with 100 kg N ha(-1) treatment, but maximum P and K content in leaf, stalk were analyzed with 100 kg N ha(-1) treatment. In second harvest the highest yield and yield criteria values depend on ecological condition. In both sowing time, P, K content in leaf and K content in stalk were determined more higher in I st harvest than anothers significantly (p < 0.01). In this research P content in leaf was observed higher than stalk content. Inspite of this K content in stalk were higher than leaf.
