Abstract

To increase the yield and improve some quality parameters of vegetables, which have an important place in human nutrition, it is possible by feeding them in a balanced and sufficient level. As the quality parameters of vegetables, external quality parameters (such as shape, size, colour) and internal quality parameters (vitamins, protein, carbohydrates, nutrients, and NO3 and NO2 amounts) are emphasized. Internal quality parameters of vegetables are important not only for people's nutrition, but also for their health. The high amounts of nitrate accumulated by some vegetables (spinach, lettuce, purslane, arugula, cress, parsley, etc.) is very important for human health. This study was carried out to determine the effect of different doses of nitrogen, magnesium and ferrous fertilizer applications on the nutrition and quality of the parsley plant. The study was carried out as a pot experiment in the greenhouse and parsley plant was grown. Three different fertilizers were applied to parsley: Nitrogen (as ammonium nitrate, 33% N), Magnesium (as magnesium sulphate, 16% MgO) and Iron (as iron sulphate, 20% Fe). As control application, 15-15-15 compound fertilizer (10 kg / da N-P2O5 and K2O) was applied. Application doses of elements was 13-16-19-22-25-28 and 31 kg / da for N; 4-8-12-16-20-24 and 28 kg / da for Mg; and 0.8-1.6-2.4-3.2-4.0-4.8-5.6 kg / da for Fe. The study was carried out in 66 pots with 3 replications. The effect of increasing application doses of nitrogen fertilizer was significant at 1% level on the contents of NO3, NO2, chlorophyll a, chlorophyll b and total chlorophyll of the parsley plant and was significant at %5 level on vitamin C. The effect of increasing application doses of magnesium fertilizer was significant at 1% level on the contents of C vitamin, chlorophyll a and chlorophyll b and total chlorophyll of the parsley plant and was significant at %5 level on amounts of NO3, NO2. The effect of increasing application doses of iron fertilizer was significant at 1% level on the contents of chlorophyll a, chlorophyll b and total chlorophyll of the parsley plant and was significant at %5 level on NO3. The effect of these treatments on NO2 and C vitamin contents was not insignificant.
