Four different production methods applied on three genotype of lettuce (Archimedes RZ, Santoro RZ, Kibou RZ) – have been estimated in a two-year experiment carried out at the Agricultural University of East Sarajevo. The experiment has been conducted during two-year period; lettuce was cultivated by using four different mulch materials: black PE foil, agro textile, a combination of PE foil and agro textile; control variant (bare soil). After harvesting lettuce, evaluated the content of the following minerals (N, P, K). The values of nitrogen content tend to increase from bare ground (7.47%) to a covered soil (7.98%). The reaction genotype on variants coverage shows an interaction effect. Type of material for covering soil also has an influence on the content of potassium. The highest potassium content of 4.87% was recorded at the variant of covering with agro textile, or by 18% more in comparison to the control variant.
