Abstract

Since the morphological attributes of the seedling in the nursery stage determine widely the success of the plant after afforestation, the producers of forest seedlings must find available, cheap and nature-friends products to replace chemical fertilizers but with maintaining their ability to improve the morphological traits of seedlings. The main objective of this study was to investigate the effect of 04 doses of rosemary (Rosmarinus officinalis L.) manure used as bio fertilizer on the early growth of holm oak (Quercus ilex L.). 5 treatments in total, 4 are resulting from the dilution of the stock solution of rosemary manure (5%, 10%, 15% and 20%) compared to a control treatment (tap water), are used in root application weekly in the aim to assess the growth parameters after harvesting the seedlings in the end of the 9th week. The tested bio fertilizer had a large positive effect on all measured morphological parameters of Q.ilex, the dose of 5% gave the greatest values for plant height, root collar diameter, number of leaves and of internodes, and also of fresh and dry biomass. Thus, rosemary manure with a dose of 5% is recommended as suitable bio fertilizer to nurture seedlings of Q.ilex and increase their morphological qualities in nursery stage.
