A field experiment was conducted at the nursery of Hort. Res. Inst., ARC., Giza, Egypt during 2014 and 2015 seasons to study the effect of spraying with humic acid at 0, 5 and 10 ml/l and adding mixture of amino acids as soil drench at 0, 1 and 2 g/pot individually or in combinations on growth, covering rate (%) and chemical composition of seashore paspalum (Paspalum vaginatum, Swartz.) plants grown in 40-cm-diameter plastic pots filled with sand medium.The obtained results showed that all treatments caused improvement in plant height, covering rate, number of plants/pot and herb fresh and dry weights compared with control, also, chemical results of chlorophyll a, b and carotenoids content in the leaves and total sugars content in the herb. The best treatments used resulted from the combining between humic acid at 10 ml/l and mixture of amino acids at 2 g/pot which recorded the highest means.Hence, in order to get the best growth and quality of paspalum plants, it could be recommended to spray with humic acid at 10 ml/l and adding a mixture of amino acids as soil drench at 2 g/pot six times with one month interval.
