This paper presents the results of two mineral fertilizer trials comparing different methods of nitrogen application on wheat (Triticum aestivum L.), cultivar 1RN-526-63. They were carried out at the Mococa Experiment Station, in low land conditions, and with irrigation, during the years of 1971 and 1972. Nitrogen had great effect on yields. The best methods of nitrogen application were 1/5 applied in the row and 4/5 applied as top dressing after 30 to 40 days from germination or the total amount of nitrogen applied as top dressing after 30 to 40 days from germination.
