AB  - Lettuce (Lactuca sativa L.) is an annual, leafy crop with a short growth in cool season. The aim of this study 
was to determine the effect of microbiological fertilisers, genotype and growing seasons on the fresh weight 
(FW), concentration of nitrate and vitamin C in the rosette (head) of red lettuce. The greenhouse experiment 
included three cultivars (‘Murai’, ‘Gaugin’ and ‘Carmesi’) of red lettuce grown in fertile soil during successive 
growing seasons: autumn, winter and spring. Three types of microbiological fertilisers: (1) mixture of fungi and 
bacteria and their products, referred to as effective microorganisms (EM), (2) containing Trichoderma spp. and 
(3) mixture of EM and Trichoderma spp., were applied for red lettuce. Microbiological fertilisers were applied in 
the soil and via foliar spray before planting. Significantly higher FW of the rosette was in spring and winter than 
in autumn. The ‘Murai’ showed significantly the highest (264.7 g) FW of the rosette in spring. Trichoderma spp. 
fertiliser and the combination of effective microorganisms and Trichoderma spp. significantly increased FW of the 
rosette for the ‘Murai’ and ‘Gaugin’ grown in autumn. The highest nitrate concentration was observed for winter 
grown ‘Carmesi’ (805.2 mg kg-1) treated by effective microorganisms, and the lowest for spring grown ‘Gaugin’ 
(62.2 mg kg-1) without microbial fertilisers. Generally, the application of microbiological fertilisers contributed 
to a significantly higher concentration of nitrate in the rosette of red lettuce. The concentration of nitrate did not 
exceed maximum level for protected lettuce (EC No 563/2002). In spring, significantly the highest concentration 
of vitamin C (12.2 mg 100 g-1 FW) was found in the ‘Carmesi’ treated with Trichoderma spp. Microbiological 
fertilisers contributed to significantly higher concentration of vitamin C in the ‘Gaugin’ and ‘Carmesi’ grown in 
winter and spring. 
This study indicated that genotype, treatment and growth season affected all the tested parameters highlighting 
the importance of application of Trichoderma spp. or the combination of Trichoderma spp. with effective 
microorganisms.
