The work presents results obtained in protected crops of lettuce under different treatments with growth promoter P& R and foliar fertilizers Agriphyte and Folimax, which are cultivated in high tunnels in southern area of Romania. It were taken in experience three varieties of lettuce: May King, Great Lakes 118 and Lollo Rossa. These treatments shows positive influence on the production and quality of lettuce. Reffer to production the best variant was in the case of the variety May King which was treated with foliar fertilizer Agriphyte (175 g/ head, 28 t/ha). At the other two varieties the best results was obtained at variants treated with foliar fertilizer Folimax. The laboratory analyses shows that the nitrate content of leaves was clearly under the maximum admissible level (2000-3000 ppm) and depends by variety and variant. The content of vitamin C was positively influenced by the treatments, especially by the ecological growth promoter P& R.
