AB  - The production of lettuce is very profitable due to the short vegetation period and the 
possibilities of its cultivation throughout the year. On average, the salad contains 94% water, 
2% sugar, 0.6% crude cellulose, 0.6% mineral matter and 1.2% crude protein. It is rich in 
vitamins C, B1 and B2, and many mineral elements. Great influence on the quantitative and 
qualitative properties of lettuce in addition to the variety and production conditions has a 
proper diet. The application of mineral fertilizers results in high yields, but their inadequate 
application can cause various problems such are: decrease in dry matter content, deterioration 
of salad quality, increase in soil acidity, degeneration of physical properties, increase in 
erosion and instability in land aggregates. In order to reduce the use of chemicals and increase 
the yield in the same time, the improvement of plant production is moving in the direction of 
introducing biofertilizers. In recent years there has been a trend of decreasing the usage of 
mineral nutrients, primarily nitrogen, phosphorus and potassium (Haytova, 2013), in which 
bio stimulators play a significant role. Therefore, the goal was to determine the impact of 
biofertilizers on the yield and quality of lettuce and to investigate the possibility of 
streamlining the crop by using biostimulators in lettuce nutrition. The two-factor experiment 
was set on a private plot in district Vranjes, East Sarajevo by using the randomized block in 3 
replications. The highest yield of lettuce was obtained in the variant with the application of 
the biofertilizer Bioplant flora (630.50 g – please state the unit), whereas the lowest was 
recorded in the control variant of fertilization (468.00 g). The highest percentage of dry matter 
was noted in the third variant of fertilization (Bioplant flora) in the variety Majska kraljica 
(6.45%), whilst the lowest percentage was reached in the control variant of the same variety 
(4.14%).
