Macroelements status in lettuce affected by different forms of phosphorus fertilization
Lettuce (Lactuca sativa L.) is annual vegetable, belonging to the family of Asteraceae. Soils in Croatia are generally poor in phosphorus, so phosphorus fertilization is of great significance. The aim of this research was to determine the effect of fertilization by different phosphorus fertilizers on the status of macroelements in lettuce. The field fertilization experiment was set up with lettuce according to the Latin square method with three fertilization treatments: T1 (control, without fertilization), T2 (phosphorus in polyphosphate form) and T3 (phosphorus in orthophosphate form). Nitrogen was determined by the Modified Kjeldahl method, phosphorus spectrophotometricaly, potassium flamephotometricaly, calcium, and magnesium atomic absorption spectrometricaly. The highest content in 100 g of fresh lettuce of phosphorus (28.24 mg P/100 g) and magnesium (48.54 mg Mg/100 g) were determined in the T1 treatment, while the highest content in 100 g of fresh lettuce of nitrogen (204.34 mg N/100 g), potassium (189.63 mg K/100 g) and calcium (122.85 mg Ca/100 g) were determined in the T3 treatment.
