Abonos verdes en el rendimiento del perejil y la fertilidad del suelo en Piracicaba, Brasil

Abstract

Los abonos verdes han sido utilizados con éxito en la producción de hortalizas como fuente de nitrógeno y como acondicionador del suelo, principalmente en áreas degradadas. Sin embargo, la información referente a esos efectos en el cultivo del perejil es escasa. Así, abonos verdes como Mucuna deeringiana, Crotalaria juncea y Crotalaria spectabilis fueron estudiados en las propiedades físicas y químicas del suelo y en la productividad de dos cultivares de perejil (Lisa Preferida y Graúda Portuguesa). Dos experimentos fueron realizados en el Departamento de Producción Vegetal de la Escuela Superior de Agricultura “Luiz de Queiroz”, en Piracicaba-SP, Brasil. Se evaluaron propiedades físicas del suelo como la densidad (real o aparente), porosidad total, macroporosidad y microporosidad, que no fueron alteradas por los abonos verdes en relación al control en los dos experimentos. También propiedades químicas del suelo como el pH, contenido de materia orgánica y nutrimentos, quienes presentaron cambios en el segundo experimento, cuando las concentraciones de Ca, P y la suma de bases aumentaron con la aplicación de los abonos verdes de forma significativa. En suelos con alta fertilidad, como el estudiado, se dificulta encontrar beneficios a partir de una única fertilización con abonos verdes. La productividad del perejil en el primer experimento aumentó en promedio 61% después de la fertilización con abonos verdes en relación al control (14,9 t ha-1), independiente de la especie de abonos verdes utilizada. En el segundo experimento, la productividad del perejil no aumentó con la fertilización de esos abonos en relación al control, posiblemente porque las condiciones abióticas afectaron la producción de biomasa de los abonos verdes y del propio perejil producido en ese ciclo.

Green manure has been employed successfully in vegetable production as a nitrogen source and for soil conditioning, especially in highly, intensively prepared soils. However, the information on the effects in parsley culture is very limited. The green manure species Mucuna deeringiana, Crotalaria juncea and Crotalaria spectabilis were studied for the physical and chemical soil properties and yield of two cultivars of parsley (Lisa Preferida and Graúda Portuguesa). Two experiments were conducted at the Crop Production Department at the Escola Superior de Agricultura “Luiz de Queiroz”, Piracicaba-SP, Brazil. The soil physical properties, such as density, total porosity, macro and microporosity, were not affected by green manure, as compared to the control in both experiments. The chemical properties (pH, organic matter and nutrients content) only changed in the second experiment, significantly increasing the Ca and P concentration and bases sum with the green manure. In soils with high fertility, such as the one in this study, it is difficult to find benefits from a single green manure. The parsley yield increased on average 61% after green manure cultivation, as compared to the control (14.9 t ha-1), regardless of the green manure species used, only in the first experiment. In the second experiment, the parsley yield did not increase because of the green manure effects, as compared to the control, possibly because, in this cycle, the produced green manure biomass and the parsley yield were affected by abiotic conditions.
