The present research had as objective: To evaluate the effect of humic acid doses Leonardite granules and humic and fulvic with macro and micro elements in lettuce (LactucasativaL.) Var. Great Lacke agroecological conditions in the province of Lamas and specific objectives: To determine the dose efficiency of humic acid granular Leonardite, and humic and fulvic with macro and micro elements in lettuce (LactucasativaL.) Var. Great Lacke, economic analysis of the treatments studied. This research work was carried out on the farm "THE PACIFIC" owned by Jorge Luis Pelaez Rivera, located in the District of Lamas, Province of Lamas, San Martin Department. To implement this experiment, we used the statistical design of randomized complete block(RCBD) with three blocks, five treatments and a total of 15experimental units. The treatments were: the application of 150and 200kg/ ha/ ac.100%humicappliedat planting, application of 30 and50 lt/Ha of action. Humic, fulvic with macro andmicroelements,50%appliedat planting and 50% to 15 DDS and absolute control. The most significant findings were: Performance and the average weight of higher plant was hit by T4 treatment (50lt.ha-1 - 50% applied at planting and 50% 15DDS) 32,302.917kg ha-1 and 0,139kg(139g) respectively, over coming statistically than the other treatments. The results of the evaluation of plant weight(g) and yield inkg. ha-1 established a positive linear relationship according to increasing application rates of humic acid and humic acid granular liquid and distinguished in that the increase in plant weigh tis greater when the application is made with liquid humic acid, treatments dose applications of granular humic acid and humic acid yielded indices liquid cost/ benefit ratio above 1
