Abstract:
The research was conducted in Taizin agricultural nursery to determine the effect of soaking with dry yeast extract, marine algae and ajwa of date palm fruits on the hardwood bases of hazelnuts cuttings under mist irrigation conditions; During the 2021 season. The cuttings were treated by soaking in each of the extracts dry yeast(10 and 20g/l), marine algae and date palm fruits at two concentrations of each (5 and 10ml/l). In addition to treatment with the IBA at a concentration of 3000ppm and its use as a witness for comparison. The results showed the superiority of yeast drenched in two concentrations (10 and 20g/l) and marine algae drenched at and ajwa of date palm fruits (10mL/L) over the rest of the treatments and the control in rooted cuttings, The yeast soaked 20g/l was significantly superior to the rest of the treatments and the control in (root length, wet and dry weight of roots, the length of the seedling, the area of the leaf surface, the content of leaves from chlorophyll a, b and total, and the wet and dry weight for seedling), It outperformed the control and yeast 10g/l, marine algae and ajwa of date palm fruits 5ml/l in (the number of roots and number of leaves), and over the control and yeast 10g/l and marine algae with two concentrations (5 and 10ml/l) and ajwa of date palm fruits 5ml/l in the number of branches. The marine algae infusion at a concentration of 10 ml/l was superior to the control, yeast 10g/l, marine algae and dates 5ml/l in (root length, root wet weight, planting length, number of branches, planting wet weight), while the date treatment gave a concentration of 10ml/l the superiority of the control and yeast 10g/l, marine algae and dates 5ml/l in (root length, wet and dry weight of roots, length of planter, number of branches, wet and dry weight of planting, total chlorophyll content of leaves).
