Nutritional status of Galia melon plants irrigated with saline water in different soils

Abstract

espanolEl experimento se realizo en 2014, en un diseno factorial completamente al azar (5x6), con tres repeticiones. Los factores fueron clases de suelo (tipic Ustipsamments, Typic Haplustults, Typic Haplustepts, Typic Ustifluvents y Typic Haplusterts) y niveles de salinidad del agua de riego (0.5, 1.0, 2.0, 3.0, 4.0 y 5.0 dS m-1). El aumento de la salinidad del agua de riego provoco un aumento en el contenido de las hojas de los macronutrientes en todos los suelos. Se observaron contenidos foliares adecuados de N, K y Mg en plantas cultivadas en todos los suelos excepto K en Typic Haplusterts y Mg en Typic Ustipsamments. Los niveles apropiados de P se observaron solo en Typic Haplustepts, y Ca solo en Typic Haplustults y tipicos Ustifluvents. El aumento de la salinidad del agua de riego provoco un aumento en el contenido foliar de micronutrientes en todos los suelos, excepto el cobre en los tipicos Ustifluvents, el hierro en los Typic Haplusterts y Typic Haplustults, y el manganeso en Typic Ustipsamments y Typic Haplustult EnglishThe experiment was conducted in 2014, in a completely randomized factorial design (5x6), with three replications. The factors were soil classes (Typic Ustipsamments, Typic Haplustults, Typic Haplustepts, Typic Ustifluvents, and Typic Haplusterts) and levels of irrigation water salinity (0.5, 1.0, 2.0, 3.0, 4.0, and 5.0 dS m-1). Increasing salinity of irrigation water caused increase in leaf contents of macronutrients in all soils. Adequate leaf contents of N, K, and Mg were observed in plants grown in all soils except K in Typic Haplusterts and Mg in Typic Ustipsamments. Appropriate P levels were observed only in Typic Haplustepts, and Ca only in Typic Haplustults and Typic Ustifluvents. Increased salinity of irrigation water caused increased leaf contents of micronutrients in all soils except copper in Typic Ustifluvents, iron in Typic Haplusterts and Typic Haplustults, and manganese in Typic Ustipsamments and Typic Haplustults
