This paper titled. "Effect of two nitrogen levels performance Lactuca sativa L. var. Crispa cv. Great lakes in hydroponic system in Santiago de Chuco - La Libertad "was held in the hydroponic greenhouse located in the district and province of Santiago de Chuco, at 3115 meters altitude. Aiming at evaluating the effect of two levels of nitrogen in the performance of Lactuca sativa L. var. Crispa cv. Great lakes in hydroponic system, for which the experimental design of complete random (DBCA) blocks, with three treatments and three replications was used respectively._x000D_ The variables evaluated were: plant height, root length, number of leaves, fresh weight and finally the yield was determined per square meter respectively._x000D_ Concerning: root length, plant height and number of leaves of lettuce was no significant (NS), thus determining the homogeneity between treatments and replications, showing the overall averages: root length (34.89 cm), plant height (22.64 cm), and number of sheets (33. 64 sheets), respectively. The weight of plant significance (*) was determined treatments, ie it significant difference at least two treatments. Thus showing TO (control): (9.33 Kg / m2) followed by T1 (9.15 kg / m2) and T2 (9.11 Kg / m2) respectively. Concluding that the control treatment (TO) presented the highest yield of lettuce in the hydroponic system.
