| description | The rapid increase in the world's population has made efficient use of water an urgent necessity. The objective of the research was to evaluate the effect of deficit irrigation and planting density on morphophysiological and productive indicators of the hybrid Py 4039 corn crop with drip irrigation. A bifactorial experiment was developed with a 4x3 arrangement with 12 treatments, four percentages of the raw sheet and three planting densities were evaluated. The calculation of the gross sheets was carried out by making the irrigation programming with the Cropwat 8.0 software. An experiment was developed in divided plots. In the main plots the effect of the percentages of the raw sheets was evaluated, which were 120%, 100%, 90% and 80% with respect to the total gross sheet, in the secondary plots the effect of the sowing density was evaluated determined by the distance between rows that was one meter and the distance between plants that was 0.15m (A); 0.20m (B); 0.25m (C), obtaining 66 666; 50,000 and 40,000 plants per ha. The morphophysiological variables measured were plant height, stem diameter, number of leaves and ear insertion height, and the productive variables: average grain weight and estimated yield. The efficient water use ratio was calculated, from the volume of water consumed, against the corn production obtained. The morphophysiological and productive variables were evaluated by means of a bifactorial analysis of variance, with the statistical program (STATGRAPHICS) Statistical Analysis System, applying the Tukey test, for the comparison of the mean, for a significance level of (P <0.05). The results obtained showed that with an irrigation sheet of 376.31 mm and a density of 66 666 plants, an average yield of 13.49 t can be achieved. ha-1, with a water use efficiency of 111.57 cubic meters per ton of corn produced. |

La investigación tuvo como objetivo evaluar el efecto del riego deficitario y la densidad de siembra en indicadores morfofisiológicos y productivos del cultivo de maíz híbrido Py 4039 con riego por goteo. Se desarrolló un experimento bifactorial con arreglo de 4x3 con 12 tratamientos, se evaluaron cuatro porcentajes de la lámina bruta y tres densidades de siembra. El cálculo de las láminas brutas se realizó haciendo la programación del riego con el software Cropwat 8.0. Se desarrolló un experimento en parcelas divididas. En las parcelas principales se evaluó el efecto de los porcentajes de las láminas brutas que fueron el 120%;100%;90% y 80% con respecto a la lámina bruta total, en las parcelas secundarias se evaluó el efecto de la densidad de siembra determinada por la distancia entre hilaras que fue de un metro y distanciamiento entre plantas que fueron 0,15m (A); 0,20m (B); 0,25m (C), obteniéndose 66 666; 50 000 y 40 000 plantas por ha. Las variables morfofisiológicas medidas fueron altura de plantas, diámetro del tallo, número de hojas y altura de inserción de la mazorca y las variables productivas: peso promedio de los granos y rendimiento estimado. Se calculó la relación uso eficiente del agua, a partir del volumen de agua consumido, contra producción de maíz obtenida. Las variables morfofisiológicas y productivas fueron evaluadas mediante un análisis de varianza bifactorial, con el programa estadístico (STATGRAPHICS) Statistical Analysis System, aplicando la prueba de Tukey, para la comparación de media, para un nivel de significancia de (P<0.05). Los resultados obtenidos evidenciaron que con una lámina de riego de 376,31 mm y densidad de 66 666 plantas se puede alcanzar un rendimiento medio de 13,49 t. ha-1, con una eficiencia en el uso del agua de 111,57 metros cúbicos por tonelada de maíz producido.Escuela Superior Politécnica Agropecuaria de Manabí Manuel Félix López2022-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtículo revisado por paresapplication/pdftext/htmlapplication/ziphttps://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/26910.51260/revista_espamciencia.v12i2.269Revista ESPAMCIENCIA; Vol. 12 Núm. 2 (2021): REVISTA ESPAMCIENCIA 2021; 131-1401390-8103reponame:Revistas Escuela Superior Politécnica Agropecuaria de Manabíinstname:Escuela Superior Politécnica Agropecuaria de Manabíinstacron:ESPAMspahttps://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/269/285https://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/269/397https://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/269/556info:eu-repo/semantics/openAccess2025-02-25T14:40:11Zoai:ojs.pkp.sfu.ca:article/269Institucionalhttp://revistasespam.espam.edu.ec/Universidad públicahttp://www.espam.edu.ec/http://revistasespam.espam.edu.ec/oai.Ecuador.1390-81031390-597Xopendoar:02025-02-25T14:40:11Revistas Escuela Superior Politécnica Agropecuaria de Manabí - Escuela Superior Politécnica Agropecuaria de Manabífalse |
