The Effect of Biofertilization and Irrigation Water Type on the Growth of Two Varieties of Geranium Plants

A global experiment was conducted in a private nursery for the purpose of studying the effect of fertilization and biofertilization methods on the vegetative and flowering growth of two varieties of geranium plants. Three factors were used in the experiment, such as the first factor using two varieties of geranium (the white and the red variety), the second factor represented the use of 3 concentrations of Biohealth biofertilizer (0.0, 5.00 and 10.00 mg L-1), while the third factor was the use of four types of irrigation water (tap, distill, well water and drainage water). Completely Randomized Design (C.R.D.), with three replicates for each treatment, each treatment contained three experimental units, with 3 pots for each experimental unit. Least Significant Difference (L.S.D.) was applied at the 0.05 level in data analysis. The results of the experiment showed that there were no significant differences between the two varieties on roots number and plant height, while it differed significantly in all other characteristics. Concentration was superior to all of the studied traits except for root length and plant height. Irrigation with distilled water produced a significant improvement in all characteristics except for root length, which was superior to the method of irrigation with well water.
