The measurements of the dry matter weight (DW) of plants which were carried out at the end of the experiment showed that the corresponding values differ among the treatments (Table 1). In general, the leaf DW reached the highest values when no NaCl was added in all treatments and it was lower in the corresponding control subtreatment (I). On the other hand, irrigation with NaCl led to the decline of the parameter in question, whereas the statistically significantly lowest value was found in the control subtreatment in which only NaCl was added (II). It is noteworthy that the application of the ceramic powder or the seaweed extract spray solution on the plants of the control subtreatments, which were irrigated with NaCl (IV and III, respectively), favored the leaf DW, contributing to the reduction in the statistically significant differences. In contrast, NaCl irrigation did not cause a significant reduction in leaf dry matter weight compared with normal conditions in the zeolite treatment, while no significant changes in leaf DW were observed when plants in this treatment were sprayed with seaweed extract (III) or ceramic powder (IV). In the EM treatment, salinity negatively affected leaf DW leading to a statistically significantly lower value compared with the subtreatment in which plants were not irrigated with NaCl (I). However, the spraying with seaweed extract of plants and the application of the ceramic powder spray solution in the subtreatments III and IV of the EM treatment favored the leaf DW, ranking its values at the same level as in normal conditions. Overall, both zeolite and the combination of compost and effective microorganisms had a statistically significant positive effect on leaf DW under salinity conditions compared with the corresponding control subtreatment (II). In addition, spraying with algal extract (III) or ceramic powder (IV) favored leaf dry matter weight in the presence of salinity in the zeolite or EM treatments leading to significantly higher values than those of the corresponding control subtreatments (Table 1). Regarding the shoot DW, it did not show a statistically significant difference between the control and the other two treatments under normal conditions. Furthermore, the addition of salinity did not significantly alter the aforementioned parameter of the control (subtreatment II), but neither did spraying with algae or ceramic powder solution in the presence of salinity (III and IV). Irrigation with NaCl (II) resulted in a statistically significant decrease in shoot dry matter weight in the zeolite treatment compared with the value of this parameter in the absence of salinity (I). However, the application of the algal extract or the ceramic powder (III or IV) appeared to help bridge the difference, bringing the shoot DW back to higher values. At the same time, the subtreatment in which NaCl was administered, in the EM treatment, did not demonstrate a significant change in shoot DW compared with normal conditions. However, a decrease in shoot dry matter weight was found when plants were sprayed with seaweed extract in the presence of salinity (III), while spraying with ceramic powder solution (IV) had no significant effect on the value of the parameter (Table 1). Furthermore, root DW showed the greatest values in the zeolite treatment and in the EM treatment in the absence of salinity compared with the control, although this fact was not accompanied by a statistically significant difference. Irrigation with NaCl and application of algal extract or ceramic powder in the presence of salinity did not cause significant changes in root dry matter weight both between and within treatments. An exception was the subtreatment III, in which the plants were sprayed with seaweed solution in the presence of salinity, in the EM treatment. In this subtreatment, the DW of the roots was significantly lower compared with that of the normal conditions subtreatment (I) (Table 1).
