Summary:The present investigation was established on the grounds of Mr. Nahum Pino Tovar, located in the Parish Pimocha, Canton Babahoyo, Province of Los Ríos, trying different sources and nitrogen fractionation schemes in the rice variety 'Iniap 15' order to: a) assess the effect of the use of various sources of nitrogen-containing chemical fertilizers on the agronomic and yield in rice cultivation b) Define an appropriate scheme of fractionation or dose of nitrogen to be applied in the cultivation of rice, and c) Economic analysis of grain yield based on the cost of treatments and sub-treatments. Nitrogen sources were: Urea, ammonium sulfate and ammonium nitrate. Fractionation schemes were: 54 - 54-72, 45 - 45-90, 60 - 60 - 60, 72 -36 to 72: 36 - 72-72 and 72-108 - 0; applied at the start of tillering; elongation stem and initiation of floral primordia, respectively.
