Abstract

Two types of biofertilizers were used in experiment conducted in the greenhouse of Zohria Garden-Horticulture search Institute, Agricultural Research Center in the 2021 and 2022 seasons, with the aim of alleviating the harmful effects of irrigation with saline water on at 0, 2000, 3000 and 4000 ppm on the Dracaena marginata plant by using the biofertilizers Nabta root at 5 cm/ liter and Vitol (micro carbon) at 1 cm/ liter. The results were as follows: adding Nabta root with saline water at a concentration of 3000 ppm gave the highest results for all shoots and roots characteristics and increased the content of chlorophyll b and carotenoid in leaves and total carbohydrates in the shoots and roots. While increasing the salinity irrigation water by more than 3000 ppm gave the lowest results in all shoots and roots characters. Increasing the salinity increased the concentration of total phenols, proline and sodium in the shoots and roots, and reduced the concentration of total indoles and calcium in the shoots and roots.
Recommendation: It is recommended to add Nabta root at 5 ml/L to the plants every month to reduce the harmful effect of irrigation water salinity.
