The present work evaluated the effect of 4 different irrigation rates on the yield of celery (Apium graveolens), through drip irrigation, at the Universidad Nacional Agraria la Molina. The deficit irrigation was carried out with a daily irrigation frequency according to the evapotranspiration demand of the crop. The irrigation time was calculated in minutes, to send it through the irrigation head, then the stopcocks were used to restrict the corresponding water demands per treatment. A Completely Randomised Design (DCA) was used with 4 treatments of irrigation rates (100%, 80%, 70% and 60% of the evapotranspiration demand) and 3 replications. Irrigation was based on daily evapotranspiration measured with a class "A" evaporimeter tank. The experimental area was 810 m², with 12 experimental units, each with one row of celery spaced at 0.2 m between plants and 0.9 m between rows. Harvesting took place 3 months after transplanting. The analysis of variance and Tukey's test (p<0.05) showed significant differences (except for height) between treatments. Treatment 1 (T1) with 100% water sheet presented greater height, diameter and weight, with 79 cm, 99.6 mm and 1.54 kg, respectively. The total volume of water applied for treatment T1 was 2660.75 m3/ha, and for treatments T2, T3 and T4 it was 1898.34, 1744.2 and 2052.48 m3/ha respectively. These values represent water savings of 19.58%, 26.12% and 13.06% with respect to T1. The highest yield was T1 with 85.4 ton/ha, followed by T2 with 74.2 ton/ha, T3 with 68.0 ton/ha and T4 with 79.6 ton/ha. Water productivity was 36 kg/m3 for T1 and T3, and 38.6 kg/m3 for T2 and T4.
