RESULTS OF DIFFERENT METHODS OF FERTILIZATION OF SOME ORNAMENTALS GROWN IN POTS

After some trials on the effect of watering Geranium through a mat made by acrylic fibers, having obtained favourable results we started some experiments of fertilization through the same type of mat, laid out on a bench.
In this paper we report results of the trials carried out with some flower crops grown in pots.
Petuniahybrida Tageteserecta, Ageratum coeruleum and Salvia splendens were used.
The five

fertilization treatments tested were:

1. control (water)

2. fertirrigation with 1 g/liter of a fertilizer with ratio N:P₂O₅:K₂O=18: 18:14

3. fertirrigation with 1 g/liter of a fertilizer with ratio N:P₂O₅:K₂O=27: 0: 0

4. fertirrigation with 1 g/liter of a fertilizer with ratio N:P₂O₅:K₂O=28:8:18

5. fertirrigation with 1 g/liter of a fertilizaer with ratio N:P₂O₅:K₂O=14:28:18

The data recorded were number of leaves and of flower produced, fresh and dry weight of the plants.
Fertirrigation was carried out through the mat on which the pots were placed or directly applyng the fertilizer to the soil of the pots.
Therefore each trial consisted of 10 treatments and each treatment was carried out using 10 plants.

The results obtained showed that fertirrigation can be carried out through the mat.
Some significant differences were observed among the different fertilizers used.
