Lettuce belongs to a group of leafy vegetable crops with special importance in human
nutrition. Along with healthy compounds lettuce can accumulate nitrate in leaves. The
purpose of this study was to examine the effects of genotype, microbiological fertilizers and
season on plant weight and nitrate content in outer and inner leaves. Green cultivars
(′Kiribati′, ′Aquino′, ′Aleppo′) were cultivated in a fertile soil, in a greenhouse trial at the
company Iceberg Salat Centar, during three successive seasons (autumn, winter and spring).
Microbiological fertilizers (EM Aktiv, Vital Tricho and combination of EM Aktiv and Vital
Tricho) were applied in the soil before trials and foliar. In spring cultivar ′Aquino′ showed the
highest head fresh weight (360.3 g). All microbiological fertilizers led to increased head fresh
weight in ′Aquino′ during autumn trial. Mainly fresh weight was higher in spring and winter
compared to autumn. Cultivar ′Aquino′ showed the highest nitrate content (...985.4 mg/kg,
autumn) in outer leaves with application of Vital Tricho. Opposite to that, the lowest nitrate
content was found in inner leaves of cultivar ′Aleppo′ (35.4 mg/kg, spring) with combination
of fertilizers. Generally, microbiological fertilizers significantly increased nitrate content in
outer and decreased in inner leaves. In both leaves the lowest nitrate level was measured in
spring season. During all trials nitrate content remained under allowed level of European
Commission Regulation (563/2002) for protected lettuce.
