Productivity of Thyme (Thymus vulgaris L.) as Influenced by Organic and Biological Fertilizers

Abstract

The aerial part of the thyme plant is the most widely used herbal medication and spice. Nutrition plays a key role on producing high quality of thyme as soil nutrients show important role in growth and quality of medicinal plants. Field trials were established during 2020-2021 and 2021-2022 seasons in Agricultural Research Station at Tag El-Ezz Experimental Farm, to study the impact of organic, mineral and bio fertilization on vegetative growth, biochemical content and essential oil of thyme Experiment were conducted in split plot design with 3 riplicats, bio fertilization was the main plot as (without and with Azotobacter), while mineral and organic fertilization as the sub plot with (100% NPK, 100% organic, 25% Org+75% NPK, 75% Org+25% NPK and 50% Org+50% NPK). Results indicated that
precence of Azotobacted imp0roved vegetative growth. chemical content and quality of leaves as well as essential oil content of thyme plant, Addition of 25% virmecompost+75% NPK recorded the highest values of various parameters. So, the application of 25% virmecompost+75% NPK in precence of Azotobacter was the recommended treatment used for improving thym vegetative and quality as well as essential oil content of thym plant.
