Nowadays soils for vegetable growing are poor in humus because the possibility of using stable dung is limited. The application of Lignofert organic carbonaceous fertilizer made of ground lignite seems to be a solution. It is intended as a fertilizer for the field or greenhouse growing of vegetables, as a component to composts, soil substrates and likewise. Lignofert effects on the formation of lettuce yield, weight of heads and NaNO3 content were studied in 2003 to 2005. Head lettuce grown in a greenhouse and in field conditions was a biological material. Average lettuce yields and average weight of heads in 2005 were statistically highly significantly higher in variants with Lignofert in comparison with the control variant grown in the greenhouse and in the field. The Lignofert effect on nitrate content in lettuce heads was not proved statistically.Keywords:
