Peru is a megadiverse country in potato production with more than 3000 varieties, at present many varieties are lost due to lack of conservation of clones, potato tubers, the experimental type research was developed in the town of Ancara, District of Paucartambo, province of Pasco. Objective. To evaluate the effect of three fertilization strategies on the yield of potato (Solanum tuberosum L) potato variety: Cancha, INIA. Materials and Methods. It was randomized complete block design with three replications, three treatments. Treatment evaluations were T1, Farmer fertilization strategy 200-230-250, T2, Yaramila integrator strategy (dose 200-400 kg/ha) and T3, YARALIVA NITRABOR strategy (dose 150-200 kg/ha). The data obtained were: plant height at 30, 60 and 90 days after planting, number of tubers per plant, weight of tubers; first, second, third in kg/plant. Results. Obtained in evaluation were plant height at 30 days, the YaraLiva Nitrabor strategy dose 150-200 kg/ha presented greater height 19 cm, followed by the fertilization strategy farmer 200-230-250 with 18 cm, the YaraMila Integrator strategy dose 200-400 kg/ha with 14 cm, the highest number of tubers presented in the T2 treatment with 15 tubers, the T3 treatment with 13 tubers, the T1 with 11 tubers. Conclusions. The best result obtained in treatment T2, strategy Yaramila integrator dose 200-400 kg/ha, the average was 2.76 kg/plant, being statistically superior the averages of treatments T3, strategy YARALIVA NITRABOR dose 150-200 kg/ha, T1, strategy fertilization farmer 200-230-250, averages were 2.10 kg/plant, 1.48 kg/plant respectively.
