Efecto de la fertilizacion nitrogenada sobre la acumulacion y distribucion de biomasa en plantas de arroz en suelos salinizados


, : Efecto de la fertilizacion nitrogenada sobre la acumulacion y distribucion de biomasa en plantas de arroz en suelos salinizados. Alimentaria 39(336): 55-59

The accumulation and distribution of dry matter in different parts and phenologic periods of the rice plants were studied. Rice plants (J104 variety) were cultivated, on a Hidromorfico soil - Gley Nodular Ferrugineous (tipic endoaqualf in the Soil Taxonomy) slightly saline (Electrical Conductivity of 4,3 dS cntdot m-1) and fertilized with different nitrogen doses (136; 161 and 186 kg cntdot ha-1) from two nitrogen sources (urea and ammonium sulphate).
