Abstract
- This investigation was carried out in two successive seasons of 2005/2006 and 2006/2007 on pot marigold plant (Calendula officinalis, L.) at the Experimental Station of Ornamental Plants, Faculty of Agriculture, Mansoura University, aiming to investigate the response of pot marigold plants to three rates of each of Nitrobein, Phosphorein and yeast. - The seeds of marigold were planted on (Sept. 25th 2005 and 2006) in the seedbeds area, and then the seedlings were transplanted after 45 days from cultivation in 30 cm clay pots filled with soil. - Biofertilizers (nitrobein and phosphorein) were added after mixing with sand each one at three rates 2.5, 5 and 10 and 1.25, 2.5 and 5 g/pot of nitrobein and phosphorein, respectively. This study revealed the following results : 1- Inoculate marigold plants with nitrobein at 10 g/pot or phosphorein at 5 g/pot with active dry yeast at (4.0 g/L) to obtain the greatest yield and quality. 2- It also enables us to decrease the use of chemical fertilization rates to reduce the pollution.
