Response of Potus Plants (Epipremnum Aureum) to Irrigation with Drainage Water of Ornamental Fish Basins and Magnesium Sulphate as Foliar Fertilizer

Abstract

Response of Potus Plants (Epipremnum Aureum) to Irrigation with Drainage Water of Ornamental Fish Basins and Magnesium Sulphate as Foliar Fertilizer. Abstract: This study was carried out at the laboratory of National Research Centre, Egypt during two successive seasons on 2012 and 2013 to study the response of potus plants (Epipremnum Aureum) irrigated by drainage water of ornamental fish basins diluted with tap water (DWOFB) at the concentrations 100% DWOFB, 75% DWOFB + 25% Tap water and 50% DWOFB + 50% Tap water) and interacted with magnesium sulphate as foliar fertilizer rate (MFFR) at the concentrations MFFR1 (25 ppm) and MFFR2 (50 ppm). The results indicated that, the plants watered with absolute fish effluent (100% fish) single or interacted with Mg 50 ppm performed the highest growth parameters, the highest percentage of carbohydrate and significant increase in photosynthetic pigments. The foliar application of Mg 50 ppm had positive effect on growth parameters and significantly increases in photosynthetic pigments. The plants irrigated with fish water effluent 75% followed by 50% had the second and the third largest average growth parameters and chemical constituents respectively.
