| description |
The nutrient uptake and partitioning in sweet pepper plants, cultivar UCR 589, was analyzed from May through November 1995, in Alajuela, Costa Rica. A complete-randomized-block experimental design with 4 replications was used. Eleven samplings at 14 days interval were carried out to measure the dry weight and the content of N, P, K, Ca, Mg and S in each plant section (root, foliage, flower and fruit) and total in the plant. Nutrient absorption by each section and the plant total was determined on the basis of the dry weight and the concentration of nutrients. Besides, the nutrient extraction for a plant density of 20833 plants ha-1 and a yield of 46.3 t ha-1 of fresh commercial fruit was estimated. The nutrient extraction order was K >N >P >Ca >S and Mg; with values of 180, 139, 26, 38 y 13 kg ha-1, respectively. Nutrient amounts in the different plant sections varied during the growing cycle. The main phenological event that regulates those fluctuations is fructification. At the end of the crop cycle, the plant accumulated N, P, Mg, K, and S, in higher amounts in the fruits and Ca mainly in the aerial part. The highest rates of nutrient absorption occurred during the stages of fruit formation and accelerated fruit growth. |

Se utilizó un diseño de bloques completos al azar, con 4 repeticiones. Se realizaron 11 muestreos a intervalos de 14 días. Se determinó el peso seco y se analizó el contenido de N, P, K, Ca, Mg y S, en cada sección de la planta. Con base en el peso seco y la concentración de nutrimentos, se estimó la absorción de los elementos por cada tejido y en total de la planta; además, se calculó la extracción de los nutrimentos con una densidad de siembra de 20833 plantas ha-1 y un rendimiento de 46,3 t ha-1 de fruta comercial fresca. El orden de extracción de nutrimentos fue K> N >P >Ca > S y Mg, con valores de 180, 139, 26, 38 y 13 kg ha-1, respectivamente. Las cantidades de nutrimentos en las distintas partes de la planta variaron durante el ciclo de crecimiento. Al final del ciclo, la planta acumula el N, P, Mg,K, y S, en mayor cantidad en los frutos y el Ca especialmente en la parte aérea. El principal evento fenológico que modula estas fluctuaciones es la fructificación. Las mayores tasas de absorción de nutrimentos ocurrieron durante las etapas de formación y llenado de los frutos.Universidad de Costa Rica2005-01-01info:eu-repo/semantics/publishedVersionArticleArtículoartículo originalhttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdfhttps://revistas.ucr.ac.cr/index.php/agrocost/article/view/6028810.15517/rac.v29i1.60288Agronomía Costarricense; Agronomía Costarricense: Vol. 29, Issue 1 (January-June); 77-84Agronomía Costarricense; Agronomía Costarricense: Vol. 29, Nº 1 (Enero-Junio); 77-842215-22020377-942410.15517/rac.v29i1reponame:Portal de Revistas UCRinstname:Universidad de Costa Ricainstacron:UCRspahttps://revistas.ucr.ac.cr/index.php/agrocost/article/view/60288/60082Derechos de autor 2024 Agronomía Costarricensehttps://creativecommons.org/licenses/by-nc-nd/4.0acceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2024-08-30T17:28:49Zoai:portal.ucr.ac.cr:article/60288Portal de revistashttps://revistas.ucr.ac.cr/Universidadhttp://www.ucr.ac.crhttps://revistas.ucr.ac.cr/index.php/index/oaijorge.polanco@ucr.ac.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:2025-08-13T10:34:30.941Portal de Revistas UCR - Universidad de Costa Ricafalse |
