| Abstract | ||
| This experiment was involved the study of three different soil mixes, loamy soil with coarse sand alone, and with manure, or with peat moss in the same volumetric, and the addition of nitrogen fertilizer ( Urea ) in concentrations 0, 150, 300, 450 mg / L. on growth of Nephrolepis exaltata . Using a mixture of loamy soil, coarse sand and manure gave the best results in fronds number and leaflet number per frond 20.6 fronds and 38.6 leaflet respectively, leaf area per plant reached 1334.81 Cm2. These plants formed a higher number of stem rhizomes and plantlet, which reached 17.33 stems 1.66 plant let and 21.83 buds. The leaves of plant planted in the previous media gave a higher quantity of phosphors 0.460% and 0.376% after three months from the beginning of plant treatment, at the end of study and higher quantity from chlorophyll 60.10 mg / gm as a fresh weight. There are no differences between the results, which were obtained from the culture of plants in media that contained a peat moss instead of manure. On the other hand, planting in these two types of media gave better results than culture in media formed from loamy soil and coarse sand only. Nitrogen fertilizer levels did not give significant results on vegetative characteristics studied where compared with control, except fronds number and leaves area. Leave area increased significantly, where the plants were fertilized with nitrogen fertilizer. Using high concentration 450 mg N / L decrease most vegetative characters .Yet , planting N. exaltata “Bostoniensis” in media contain manure or peat moss with the addition of nitrogen fertilizer at 150 or 300 mg N / L weekly, gave the best results. | ||
