The research work titled “Four organic matter (hen droppings) doses in the farming of lettuce (Lactuca sativa) var. Grand Rapid Waldeman´s Strain, under Lamas province agroclimatic conditions” was carried out. The aim was to evaluate the effects of four organic matter doses in the yield of lettuce farming, to determinate the dose resulting in the highest crop yield and to perform the economic analysis of the studied treatments. A randomized block design with five treatments and five repetitions was used. The evaluated variables were: plant height (cm), plant weight (g), stem diameter (cm), number of leaf per plant, yield (kg.ha-1) and economic analysis. Results shows that treatments T3 and T4 gave the highest average yield with 41695 and 37881,97 kg.ha-1, and gave the highest economic profitability, 18.10% and 15.69% respectively
