The paper presents study results on the effects of different nitrogen fertilizer rates, planting date and genotype on the dry matter content in lettuce. The reseach results obtained show that the dry matter content is higher in the lettuce grown at the winter planting date (5.30%) compared to the autumn date (4.94%). The increasing nitrogen rates used did not have any significant effect on the dry matter content and the differences expressed were not statistically significant. The highest dry matter content at both planting dates was achieved in the variant without fertilization that is in the control variant. A significant variability between the investigated genotypes was recorded in the dry matter content. The Rovel genotype had the lowest dry matter content at both planting dates (4.72% at autumn and 5.15% at the winter dates). As regards the Marmer genotype, the lowest dry matter content was registered at the autumn planting date being 5.02%, as opposed to the 5.59% content achieved at the winter date. The dry matter content at the autumn and winter planting dates in the genotype Bernado was 5.08% and 5.15%, respectively.
