Abstract EN

This study was conducted in University of Tikrit during the 2019 agricultural season, to study the effect of treatment with rooting hormone, paraffin and fungicide on the success of cultivating the offshoots of two varieties of date palm (Khastawi and Zahdi) in Gypsifrious Soil.

The experiment planned RCBD, with three replicates.

.

The cultivar had a significant effect on the studied traits, as the variety Khastawi outperformed in the percentage of success offshoots, leaf length, pinnae length and the number of roots as it reached 86.27% , 30.20 cm, 16.87 cm, 15.67 roots, respectively, while the Zahdi variety outperformed the average number of leaves as it gave an average of 3.80 a sheet.

17.00 cm, 21.50 root, respectively, while the comparison treatment gave the lowest average for the aforementioned traits.

As for the effect of the interaction between the cultivar and the rooting treatments, the cultivar Khastawi and Zahdi in the treatment of the rooting hormone plofid and the fungicide the highest success rate of 100% , and the cultivar of Zahdi in the same treatment gave the highest rate of the number of leaves and the length of pinnae, while the variety Khastawi in the same treatment gave the highest rate of leaf length The length and number of roots, while in the comparison treatment, the ascetic variety gave the lowest success rate of 57.67% .
