Influence of nitrogen, phosphorus and potassium fertilization on the content of micronutrients in aubergine fruits (Solanum malongena L.) growing in organic substrates
Summary.

In 2003-2004 vegetation studies were conducted with cultivation of aubergine (Solanum malongena L.) cultivars ‘Epic F1’ and ‘Solara F1’ which aim was to estimate the influence of nitrogen, phosphorus and potassium fertilization on the content of micronutrients in fruits in case of two mentioned cultivars of aubergine grown in organic substrate in unheated protection tunnel. The tested media were: 1) highmoor peat (limed to pHH2O 6.5), 2) pine bark + fen peat (v:v = 1:1). Three levels of fertilization (mg·dm-3) were used in the studies: 1) low: N – 300, P – 265, K – 500, 2) standard: N – 400, P – 350, K – 665, 3) high: N – 500, P – 440, K – 830, while maintaining stable macronutrient proportions at N:P:K = 1:0.9:1.7. There were significant differences of nutrient content between cultivars only in the case of zinc, while between type of substrate – in the case of iron and manganese. Higher average content of manganese was found in fruits of plants grown in highmoor peat comparing to those grown in mixed substrate, while the opposite relation was stated in the case of iron. There was no influence of fertilization level on the average content of: iron, manganese, zinc and copper in aubergine fruits.
