Acumulación de materia seca del cultivo de pepino (Cucumis sativus L.) en invernadero

Abstract

El estudio de la fisiología del crecimiento de los cultivos hortícolas bajo la modalidad de agricultura intensiva protegida en invernaderos es importante en la generación de información sobre algunos aspectos que permitan mejorar el manejo agronómico, por ejemplo en lo referente a nutrición mineral. Por la importancia del pepino en este contexto, se cultivó en los invernaderos de la Universidad Autónoma Chapingo (México) el híbrido “Saber” con cuatro concentraciones de la solución nutritiva universal de Steiner (25, 75, 125 y 175%), bajo un diseño experimental de bloques al azar con tres repeticiones, en el periodo comprendido entre abril y agosto e 2006. Durante 135 días después del trasplante, se cuantificó cada 15 días la materia seca de tallos, hojas, zarcillos, flores, frutos, total y el rendimiento. Con la solución nutritiva al 175% se obtuvo mejor expresión del crecimiento a través de mayor acumulación de materia seca y rendimiento de 8,20 kg por planta, que superó en 59, 22 y 15% a lo obtenido con las concentraciones del 25, 75 y 125%, respectivamente, lo que muestra la respuesta del cultivo de pepino al manejo diferencial del suministro de nutrimentos, ya que con la solución nutritiva al 25% de concentración se presentaron valores más bajos de rendimiento y de acumulación de materia seca total y de órganos de la planta.
