Abstract

An experiment was conducted to study the effect of salinity on yield characters of African marigold. In this study, saline water was used as irrigation water for two African marigold varieties (Coimbatore Local and Nilakkottai Local). Six salinity levels were imposed (20, 40, 60, 80, 100 mM and Control). The treatments were given by irrigating the plants with desired amount of Sodium Chloride (NaCl) dissolved in irrigation water. The observations were made on yield characters viz., number of flowers, flower diameter (cm), single flower weight (g) and flower dry weight (g). Among the varieties, Coimbatore Local tolerated more salinity than Nilakkottai Local. All the parameters significantly reduced with the higher concentrations of salts.
