The work presents results obtained in protected culture of the lettuce for autumn – winter harvest under different treatments with growth promoter (V4 -P & R) and foliar fertilizers (V2 Folimax, V3 Agriphyte) grown in the south of Romania in plastic high tunnels. These two varieties used in the experience have been distinguished by both vegetation period (125 days and May King and 85 days at Great Lakes 118), as well as by specific reaction to the treatments application. Plant growth was influenced differently by the two foliar fertilizers, the biggest differences from the control was on V3 (Agriphyte) for the variety May King and on V2 (Folimax) for Great Lakes 118. Plant height has increased on average by 1-1.5 cm; diameter rosette of leaves has reached 32 cm , respectively 28 cm; average weight of the lettuce head has exceeded the control with 17% for variety May King and with 4% for Great Lakes 118. Concerning the production of lettuce (t/ha) the influence of experimental treatments was similar to that observed on plant growth. From the control, the greatest differences in production were obtained in variant treated with Agriphyte (17.5 %) for the variety May King and to the fertilizer with Folimax, in the case of the variety Great Lakes 118 (4 % ). The smallest production differences for both varieties was registered at V4 (P&R).The results show that for the variety May King the yield was 24 t/ha (V1 control) to 28 t/ha (V3 Agriphyte . Variety Great Lakes 118, gives yield average by 26 t/ha (V1control) to 27 t/ha (V2 Folimax).
