The main problem that concerns alfalfa growers in Peru is the low yield and persistence reach by this crop due to the restricted access to quality seeds, the ignorance about alfalfa variety selection, an incorrect fertilization method or its absence, and water scarcity or drought. In order to solve this problem, the purpose of this research was to evaluate the adaptation of three alfalfa varieties as an alternative to local varieties and to estimate the effect of phosphorous fertilization in plant structure, quality and crop yield during stand establishment and production phases. The evaluated group treatments were the factorial combination of three alfalfa varieties (Moapa 69, SW 8210 and CUF 101) and two phosphorus levels (0 kg/ha y 35 kg/ha) in a completely randomized design with three repetitions. The variables evaluated in this study were as follows: plant density, stem/plant, height, root length, leaf:stem ratio, aboveground biomass, and root weight during stand establishment phase and yield, accumulated yield, growth rate, height, aboveground biomass and leaf:stem ratio during production phase. The fertilization with phosphorus enhanced (p<0.05) seedlings survival and its development after sowing and during production phase the alfalfa yield was increased. For the first 90 days, the varieties SW8210 and CUF101 showed the highest values (p<0.05) for height and density and Moapa 69 had the best leaf/stem ratio score and stem/plant number. In the production stage, Moapa 69 and SW8210 show higher values than CUF101 in terms of plant yield (kg DM ha-1 and kg DM ha-1day-1). The response patterns to phosphorus fertilization were similar, so the interaction between alfalfa variety and phosphorus dose was not significant over the course of the study.
