The objective of the research was to evaluate the response of the localized application of earthworm humus in the potato crop of the Canchán INIA variety. The study was carried out in the Grau province of the Apurimac department. The study variables were the vegetative growth represented by the indicators: percentage of emergence, percentage of lateral shoots, plant height between periods and the number of stems between 30, 60 and 90 days after sowing. With a completely randomized block design. The results show that there are significant differences (Sig.<0.05) between the treatments, being the localized application of earthworm humus at 0.5 Kg/plant the highest averages of emergence and lateral shoots of 95%. The results in the yield parameters are reported greater than 0.5 Kg/plant, among which the tuber yield of 32.1525 t/ha stands out, tuber weight per plant of 868.1375 g/plant, tuber diameters between 36.58 mm to 42.7175 mm and 13.9625 tubers/plant. In conclusion, the localized application of earthworm humus at 0.5 kg/plant has a better effect on the productive parameters of the potato crop compared to the broadcast application of 2 kg/m2 of earthworm humus.
