The rice Oryza sativa L. is one of the crops with greater expansion within the San Martin region, because of its high demand and source of employment. The research aimed to determine the optimal seed densities (kg.ha-1), in two varieties of rice that allow obtaining better yields and grain quality under the direct sowing system, for which five (5) densities of Oryza sativa L. were tested. The yield and quality in the varieties INIA-509 la Esperanza and Bellavista were evaluated, and at the same time a comparison of the grain yield of the two varieties was made, making the respective economic analysis for each treatment. The study was carried out in the San Martin region, district of Juan Guerra, in the station El Porvenir INIA, with a west longitude 76° 21' 15", south latitude 06° 36' 15", and an altitude of 320 m.a.s.l. The completely randomized block design (DBCA) was used, with a factorial arrangement of 2 (varieties) x 5 (seed dosage) and four replicates. The obtained results indicate that the best amount of seed is 50 kg.ha-1 reaching a number of 315.06 panicles per m2, the variety Bellavista is the one that presented the greater percentage 0.42 % of incidence of Burkholderia glumae, yield with 14% of humidity where the variety Bellavista reaches in average 7.42 t.ha-1 and the Hope 6.97 t.ha-1 . As for the benefit-cost ratio, it was 1.38 nuevos soles. In terms of yield with 14% humidity, the Bellavista variety reaches an average of 7.42 t.ha-1 and the Esperanza 6.97 t.ha-1 . As for the benefit-cost ratio, it was 1.38 nuevos soles.
