Abstract
La presente investigación fue conducida en el predio “Maicero”, ubicado en Santiago de Chuco, a una altitud de 3106 msnm y una temperatura promedio de 13 ºC, con el objetivo de determinar el efecto de distintos niveles de Guano de las Islas en el rendimiento y calidad de Spinacia oleracea L. var. Viroflay. Los niveles de Guano de las Islas estuvieron conformados por 0.0, 0.5, 0.8 y 1.0 t.ha-1 para los tratamientos T0, T1, T2 y T3 respectivamente. En el experimento, conducido bajo condiciones de campo en DBCA por 65 días, se evaluó la altura de planta, el número de hojas, el ancho de hoja, el peso fresco, el peso seco, el rendimiento y la calidad de la espinaca, obteniéndose efectos estimuladores de los tratamientos fertilizados (T1, T2 y T3) sobre el rendimiento y calidad de la espinaca, con incrementos significativos en la altura de planta de 22.87 a 33.47 cm, en el número de hojas de 12.45 a 13.70 unidades, en el ancho de hoja de 11.37 a 12.55 cm, en el peso fresco de 66.85 a 85.76 g, en el peso seco de 5.92 a 6.90 g, en el rendimiento de 27.81 a 35.67 t, y en la calidad de 8% a 7%, en relación al tratamiento testigo respectivamente. Los datos expuestos fueron procesados mediante análisis ANVA y la prueba de medias de Tuckey al 5 % de significación, utilizando la hoja de cálculo de Microsoft Excel. Se concluye que, la aplicación de Guano de las Islas en dosis de 0.8 t.ha-1 (T2) presenta el mejor efecto numérico sobre el rendimiento y calidad de la espinaca.
ABSTRACT The present investigation was conducted in the “Maicero” property, located in Santiago de Chuco, at an altitude of 3106 meters above sea level and an average temperature of 13 ºC, with the objective of determining the effect of different levels of Guano de las Islas on the performance and quality of Spinacia oleracea L. var. Viroflay. The Guano de las Islas levels consisted of 0.0, 0.5, 0.8 and 1.0 t.ha-1 for treatments T0, T1, T2 and T3 respectively. In the experiment, conducted under field conditions in DBCA for 65 days, plant height, number of leaves, leaf width, fresh weight, dry weight, yield and spinach quality were evaluated, obtaining stimulating effects of fertilized treatments (T1, T2 and T3) on the performance and quality of spinach, with significant increases in plant height from 22.87 to 33.47 cm, in the number of leaves from 12.45 to 13.70 units, in width of 11.37 to 12.55 cm leaf, in the fresh weight of 66.85 to 85.76 g, in the dry weight of 5.92 to 6.90 g, in the yield of 27.81 to 35.67 t, and in the quality of 8% to 7%, in relation to the control treatment respectively. The exposed data were processed by ANVA analysis and the Tuckey means test at 5% significance, using the Microsoft Excel spreadsheet. It is concluded that, the application of Guano de las Islas in doses of 0.8 t.ha-1 (T2) has the best numerical effect on the performance and quality of spinach.
