Fertilization of experimental maize hybrid INIAP H-603 based on agronomic efficiency of nitrogen
We carried out field experiments during the 2013 dry period, in Jipijapa, Bolívar and Santa Ana (Manabí-Ecuador) to find the effect of fertilization using N, supplemented with other nutrients deficient in the soil, for determining the optimum nitrogen dose (OND), based on agronomic efficiency calcul...

| description | We carried out field experiments during the 2013 dry period, in Jipijapa, Bolívar and Santa Ana (Manabí-Ecuador) to find the effect of fertilization using N, supplemented with other nutrients deficient in the soil, for determining the optimum nitrogen dose (OND), based on agronomic efficiency calculations (AE), of the maize hybrid INIAP H-603. We used 0-100-150-200 y 250 kg/N.ha-1, with and without supplementary fertilization [two applications of Biol fertilizer and 50 kg.ha-1 of minor nutrients II (Zn 4%, Mn 2.5%, Cu 1%, B2O3 1.5%, and S 5%)]. Maize yield was positively affected by fertilization with N and other nutrients. Correlation analysis showed that over 99% of the increase was caused by the fertilization with N. The increase in yield with the highest levels (200 and 250 kg/N.ha-1) confirmed that a genetically-improved plant material requires high levels of nutrients to achieve its yield potential. For this reason, from the analysis of OND, we found that the optimum dose was 200 kg/N.ha-1, after considering the existing AE. |

Se utilizaron 0-100-150- 200 y 250 kg/N.ha-1, con y sin la fertilización complementaria [dos aplicaciones de Biol y 50 kg.ha-1 de Nutrimenores II (Zn 4%, Mn 2,5%, Cu 1%, B2O3 1,5%, y S 5%)]. La productividad del maíz, fue evidentemente influenciada en términos positivos por la fertilización con N y en forma complementaria; los análisis de correlación mostraron que más del 99% del incremento de producción es causado por la fertilización con N. La superioridad en los rendimientos con los niveles más altos (200 y 250 kg/N.ha-1) confirman que un material genéticamente mejorado requiere de una nutrición elevada para manifestar su potencial productivo; por ello, los análisis de estimación permiten establecer en 200 kg/N.ha-1 la DON, tomando en consideración las EA encontradas.Escuela Superior Politécnica Agropecuaria de Manabí Manuel Félix López2016-12-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlapplication/ziphttps://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/123Revista ESPAMCIENCIA; Vol. 7 Núm. 2 (2016): REVISTA ESPAMCIENCIA 2016; 109-1161390-81031390-597Xreponame:Revistas Escuela Superior Politécnica Agropecuaria de Manabíinstname:Escuela Superior Politécnica Agropecuaria de Manabíinstacron:ESPAMspahttps://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/123/142https://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/123/678https://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/123/679info:eu-repo/semantics/openAccess2025-02-25T14:34:26Zoai:ojs.pkp.sfu.ca:article/123Institucionalhttp://revistasespam.espam.edu.ec/Universidad públicahttp://www.espam.edu.ec/http://revistasespam.espam.edu.ec/oai.Ecuador.1390-81031390-597Xopendoar:02025-02-25T14:34:26Revistas Escuela Superior Politécnica Agropecuaria de Manabí - Escuela Superior Politécnica Agropecuaria de Manabífalse |
