Resumen
El presente trabajo de investigación para determinar la concentración foliar de nutrientes en el cultivo
de mandarina variedad W. Murcott en Santiago – Ica, se llevó a cabo en la campaña 2023 – 2024 del
Fundo “Santa Esperanza”, ubicado en el Distrito de Santiago que corresponde a la zona media del
Valle de Ica, en un suelo de Textura Franca, teniendo como objetivo principal: El determinar la
capacidad de asimilación de nutrientes en la mandarina W. Murcott en el sector de Santiago – Ica.
Para la elaboración del presente estudio, se tomaron los datos analíticos de laboratorio que fue
reportado por la empresa Certificadora Peruana (CERPER) de muestras foliares tomadas en cuatro
ocasiones y de frutos en tres ocasiones que se usaran para elaborar las figuras presentes en el capítulo
de Resultados, y estos nos mostraron que las plantas de mandarina en el Fundo “Santa Esperanza”
presentan niveles óptimos de Nitrógeno en todas las etapas de muestreo; lo mismo sucedió con el
Fosforo foliar, el Calcio también tuvo un buen contenido excepto en el tercer muestreo foliar en
febrero que bajo su contenido; el Potasio se recuperó en los dos muestreos foliares, el Magnesio tuvo
un comportamiento irregular, en el primer y tercer muestreo estuvo bajo, luego se puso optimo en el
segundo y cuarto muestreo foliar. El Boro sobrepaso el nivel de exceso en el follaje, en cambio el
Hierro esta alto en todos los periodos, al igual que el Zinc y el Manganeso. Solo se debe tener cuidado
con los niveles altos de Boro en todo el follaje en las cuatro etapas del muestreo.
The present research work to determine the foliar concentration of nutrients in the mandarin crop variety W. Murcott in Santiago - Ica, was carried out in the campaign 2023 - 2024 of the Fundo “Santa Esperanza”, located in the District of Santiago that corresponds to the middle zone of the Valley of Ica, in a soil of loamy texture, having as main objective: To determine the assimilation capacity of nutrients in the mandarin W. Murcott in the sector of Santiago - Ica. Murcott mandarin in the Santiago - Ica sector.For the elaboration of the present study, analytical laboratory data were taken from foliar samples taken on four occasions and from fruits on three occasions, which were used to elaborate the figures in the chapter on Results, and these showed us that the mandarin plants in the Santa Florencia Estate present optimum levels of Nitrogen in all the sampling stages; The same happened with foliar phosphorus, calcium also had a good content except in the third foliar sampling in February when its content was low; potassium recovered in the two foliar samplings, magnesium had an irregular behavior, in the first and third sampling it was low, then it became optimal in the second and fourth foliar sampling. Boron exceeded the level of excess in the foliage, while Iron was high in all periods, as were Zinc and Manganese. Only the high levels of Boron in all the foliage in the four stages of sampling should be taken into account.
