Abstract: This study aimed to examine the effect of cultivar, fertiliser and irrigation, and their combined effect, on different lettuce agronomic parameters and the possible occurrence of tipburn. Two iceberg lettuce cultivars ('Umbrinas' and 'Kavir') were cultivated during summer in the open field, in the black marsh soil containing a wide calcium-to-magnesium ratio. Plants were grown at a density 32×32 cm with regular agricultural practices. Three different levels of magnesium sulfate fertiliser (100 ml, 300 ml, 500 ml solution) were added twice during the growing cycle. Plants were irrigated using a drip irrigation system and sprinklers. After harvest morphological parameters were estimated (head weight, height, diameter, number of leaves, fresh leaf weight, stem height, diameter, and fresh weight). Cultivar 'Umbrinas' showed the highest value of all parameters: head weight (557.15 g), head height (13.91 cm), head diameter (16.90 cm), number of leaves (18.73), fresh leaf weight (527.50 g), stem height (65.73 mm), stem diameter (20.32 mm), and stem fresh weight (29.65 g). Application of all levels of magnesium sulfate fertiliser did not affect observed parameters compared to the control. Drip irrigation led to significantly higher head height, diameter and number of leaves, while sprinkler irrigation significantly enhanced the values of all stem parameters. Tipburn was noticed mainly in the 'Umbrinas' cultivar in the sprinkler irrigation treatment, whereas drip-irrigated plants showed no signs of tipburn. Interaction of all three factors showed a statistically significant impact on head weight, number of leaves, fresh leaf weight, and stem height.
