This research paper entitled "Response of yield and components of the architecture of the bean plant (Phaseolus vulgaris L.) According to plant density", had as objectives: To study the response of yield and components of plant architecture according to the density and determine the economic analysis of the treatments. Was conducted between February and May 2012 in the Fundo Miraflores de la Universidad Nacional de San Martin - Tarapoto. Design We used a randomized complete block with a factorial arrangement of 2 x 5, with 3 blocks and 10 treatments. Being the Factor A = bean varieties (Panamito red and brown) and Factor B = Seeding (b1 = 15 cm x 60 cm, b2 = 20 cm x 60 cm, b3 = 25 cm x 60 cm, b4 = 30 cm x 60 cm and b5 = 35 cm x 60 cm). The variables evaluated were: Percentage of emergency, lateral branches per plant, nodes per lateral branch, Knots on main stem nodes per square meter, length of internodes on main stem, plant height, 100-seed weight, yield per meter square and economic Analysis. The most significant findings were that the variety panamito was statistically averaged red to brown in panamito g.m2 performance, performance kg.ha-1 and weight of 100 seeds. G.m2 performance variables, performance kg.ha-1, nudos.m2 number and length of internodes in the main stem, determined based positive linear responses to increasing plant density. Treatments that threw rates B / C greater than 1 were the T1, T2, T3, T4, T6, T7 and T8. As T3 treatment (133,333 plants.ha-1 PR) that yielded the highest value of the B/C with 1.26, defining a 25.93% return
