This research was carried out in the facilities of Agroindustrial UPAO SAC, located in Salaverry, Trujillo, La Libertad, from December 2018 to February 2019. The objective was to compare the effect of the nitrogen dose on spinach production Spinacea oleracea L. (Chenopodiaceae). It was done through the design of Completely Random Blocks with five treatments and five repetitions. An analysis of variance was performed, to determine the differences and Duncan's significance test at 0.05% probability, to evaluate the best treatment. The sowing had a distance of 0.30 m between rows and 0.15 m between plants corresponding to a planting density of 222,222.00 plants / ha; the area for the experiment was 115.5 m2. The application of the nitrogen fertilizer dose (ammonium nitrate) was carried out 10, 25 and 40 days after sowing. The doses of the fertilizer of ammonium nitrate were 50, 100, 150 and 200 kg of N / ha; No dose of used fertilizer has been applied. The evaluations of the parameters of number of leaves and the height of the plant were on days 25, 40 and 55 after sowing. The highest number of leaves and plant height was obtained in the T3 treatment (100 kg N / ha), in all the evaluations carried out, surpassing all the treatments, especially the T1 treatment (Control), which did not have No fertilizer application of N (ammonium nitrate). The maximum yield (t / ha) was obtained with treatment 3 (100 kg of N / ha) with 20.45 t / ha, surpassing the other treatments, especially treatment 1 (Control), which ranked last with 6.13 t / ha
