Juárez Alarcón, Luis Mariano. (2020). “Efecto de la fertilización fosforada en el rendimiento de quinua (Chenopodium quinoa willd) adaptada a la zona norte de la provincia de los Ríos”.

The Quinoa (Chenopodium quinoa Willd) is an Andin crop that currently increase your production and area around the world, because the grain has a high amino acids and proteins. Therefore, this has motived make many research about the development and production of Quinoa crop, in this case evaluate the effect of fertilization phosphorus in the performance Quinoa’ crop adapted to north zone Los Ríos’ province. This research did development in the campus “La María” property “Quevedo’ Technical University” located in the 7, 5 km road Quevedo - El Empalme. Mocache Canton, Province of Los Ríos. It used DCA with 5 treatments (0-25-50-75-100 Kg P ha-1) each of them with 5 repetitions. The variables more evaluated in this research: at to 40 -80 days after of planting (dds) were, high of plant (cm), stem diameter (cm) root length (cm) dry matter (g) total biomass (g) and at 96 dds it stablished the harvest rate (IC) and grain performance (g). The results to get at 80 dds, highlight the higher averages to T5 treatment: for the variable high of plant with 115,24 cm, stem diameter was 0,64 cm, root length with 11,04 cm, fresh root weight was20,8 g, fresh weight part air with 161,42 g, in total biomass was 667,70 g m-2. While that in the variables were evaluated at harvest: harvest rate and grain performance too highlight T5 with 0,41 IC and 272,90, g m-2 respectively. With this research to prove that a phosphor dose of 100 Kg P ha-1 to get the higher performance of grain in the north zone of Los Ríos province.
