The present study deals with biochemical and physiological methods for assessment of the optimal nutrient supply for the growth and development of garden rocket (Eruca sativa Mill.), edible vegetable. Two nitrate (0.3; 0.6 g N dm⁻³ of medium) and three potassium doses (0.3; 0.6; 0.9 g K dm⁻³ of medium) in the form of sulphate or chloride were examined. At the higher nitrate dose and the sulphate form of potassium the intense green colour of leaves, higher content of nitrates, flavonoids, L-ascorbic acid and lower carbohydrates content correlated with elevated growth parameters, e.g. the number of leaves and partially plant fresh weight. The proline and anthocyanin contents weakly diversified the nutrient supply. Despite the lack of modification in the photosynthetic pigment concentration, the chlorophyll fluorescence parameters were significantly improved when the higher nitrate dose accompanied the sulphate form of potassium (higher values of fluorescence decrease, maximum quantum efficiency of PSII photochemistry in the dark-adapted state, photochemical quenching and lower values of the fraction of absorbed light energy not used for photochemistry). The biochemical and photosynthetic parameters corresponding to the morphological characteristics (leaf colour, number of leaves and plant fresh weight) indicated that better nutrient conditions were provided to plants under the combined fertilization of the higher nitrate dose and the sulphate form of potassium.

A vegetation experiment was conducted in 2001–2002 in an unheated greenhouse on the effect of differentiated nitrogen fertilization on yield and quality of garden rocket. Nitrogen was used in three forms, i.e. lime saltpeter, urea and ammonium sulphate, and in three doses: 0.2; 0.4; 0.6 N·dm⁻³ (2001) and 0.25; 0.50; 0.75 g N·dm⁻³ (2002). The plants’ growth, yield and content of nutrients were evaluated and an chemical analysis of the substrate after the harvest was conducted. The studies pointed out a possibility of cultivating garden rocket in autumn in an unheated greenhouse. A higher yield of fresh weight was obtained in the treatments with lime saltpetre and urea as compared with ammonium sulphate. Increased doses of nitrogen, independently of the kind of the applied fertilizer, caused a decrease of the yield of rocket fresh weight. The studied plants of garden rocket were characterized by a high content of dry matter, vitamin C, protein, potassium and calcium. The content of nitrates in the dry matter of leaves was within the range 0.02–0.98%, depending on nitrogen dose and the year of studies. The application of 0.2–0.25 g N·dm⁻³ of the substrate in the autumn cultivation of rocket proved to be the most advantageous in view of the highest yield of fresh weight, the highest content of vitamin C and the lowest proportion of nitrates in the leaf dry weight.

We studied the effect of differentiated nitrogen-potassium fertilization upon the growth, yield and chemical composition of garden rocket leaves grown in unheated greenhouse in autumn. Two nitrogen doses were applied (0.3 and 0.6 g dm⁻³) in the form of calcium saltpeter and two doses of potassium (0.3, 0.6 and 0.9 g dm⁻³) in the form of chloride and sulfate. The increased amounts of nitrogen and potassium generally contributed to the increase of fresh leaf weight yield. Plants nourished with KCl had larger concentrations of L-ascorbic acid, chlorine and calcium, whereas the contents of protein, sugars in total, as well as sulfates were smaller, as compared to plants nourished with K₂SO₄.
