| Abstract | ||
| With the aim to know role of irrigation level and (Driwater) addition into two soils calcareous and gypsiferous on growth and yield of Gladiolus (Gladiolus hortulanus) the factorial experiment conducted by using Split - Split Plot Within Completely Randomized Block Design with three factors and tow replication .the firs factor included two types of soils calcareous and gypsiferous (main plot). The second factor included three levels of added water after depletion (60, 40 and 20%) from available water (sup-plot), and The third factor included preservative of the moisture (Driwater) with the treatment comparison without the addition (sup-sup plot),Led added of (Driwater) significant decrease in reducing number of irrigations and the depth of applied water and increase in water use efficiency also significant increase in corms weight and total yield corms and cormelet amounted 13.15 ,15.6% respectively, the calcareous soil showed a significant superior clear on the gypsiferous soil achieving increase in leave area and duration to first basal floret opening, while Characterized by soil gypsiferous with reducing the depth of applied water and increase in water use efficiency and increase in the number of florets opened total through vase life and corms diameter and cormelet number. Showed interaction bilateral between soil type and irrigation level at treatment a level of addition after the depletion 60% of available water in calcareous soil significant increase in plant height and and corms weight is superior to the rest of the transactions. Showed interaction tripartite for three factors at treatment add (Driwater) in soil calcareous in level of addition after the depletion 60% of available water significant increase in corms diameter and cormelet weight is superior to the rest of the transactions. | ||
