The influence of different fertilizer sources on lettuce yield and quality was studied. The field experiment was carried out on alluvial meadow soil . The experiment included three fertilizer sources: mineral fertilizer, farmyard manure and foliar fertilization. The highest yield values from lettuce were obtained in the variants with mineral fertilization. A beneficial effect of the lettuce quality was observed: high values of soluble sugars and vitamin C content, low level of cellulose and reduced nitrate content.
