Abstract

The present investigation was carried out to evaluate the effect of foliar spray by  fulvic acid extract at concentrations of 3.5 and 7cm/L on plants. Foliar spray was applied on plant leaves 3times. The first time was done after the complete Pancratium maritimum plants reached 15cm height. The second time was after one month from the first one. Finally, the third one was performed after cutting flowers. Beside that the chemical fertilizations were added as follows: urea (46.5%N), calcium superphosphate (15.5%P) and potassium sulphate (48.5%K) at different rates of 100, 75, 50and 25% from the recommended dosage on this  plant. Data were recorded for the vegetative growth, flowering, bulbs yield and chemical composition and it was a matter of importance to conclude that for obtaining a healthy outdoor plants of Pancratium maritimum for long period with good vegetative and flowering traits, it is recommended to fertilize this plant with 75% NPK +3cm  fulvic acid or 50%NPK+5cm  fulvic acid under similar conditions of this investigation.
