The nutritional status of eggplant (Solanum melongena L.) depending on plant training method and nitrogen fertilization

Abstract: The eggplant is a valuable plant mainly grown in a greenhouse and under the foil. Nowadays we have still too little informations about nutritional and fertilization need of that plant. Experiments involving eggplant of Epic F1 cv. were carried out in 2004–2005 in unheated foil tunnel; the aim focused on evaluating the influence of pruning methods using plants treated with nitrogen in form of N-NH4, N-NO3, NH2 applied at various rates. Achieved results revealed significantly influence of nitrogen forms on total nitrogen, phosphorus, and calcium, while no influence on potassium and magnesium contents in eggplant leaves. Instead, increasing nitrogen doses significantly elevated the nitrogen, phosphorus, and magnesium concentrations in plants. Improved light conditions within a plant profile due to cutting had positive effects on phosphorus and calcium contents in leaves as compared to plants pruned in their natural form. Considerable decrease of the subsoil pH value was recorded after applying the increasing rates of nitrogen fertilizers in a form of ammonium sulfate. Following levels of eggplant nutrition at full ripeness were considered as optimum: 0.28% to 0.45% N-NO3 and 3.70 to 4.00% N-tot. in leaves, as well as 250 to 350 mg N-NH4+N-NO3·dm-3 in subsoil.
