Abstract

Abstract
Background & Objectives: This study was conducted to evaluate the effects of organic and bio-fertilizers on yield and essential oil production of green basil in order to reducing of chemical fertilizer application

Materials and Methods: The experiment was conducted based on a randomized complete block design with six treatments and three replications in Kelardasht of Iran in 2021. The treatments were 1- vermicompost (10 t.ha-1), 2- nitroxin (2 lit.ha-1), 3- bio-superphosphate (2 lit.ha-1), 4- nitroxin + bio-superphosphate, 5- vermicompost + nitroxin + bio-superphosphate, 6- chemical fertilizer (NP: 80, 60 kg.ha-1).

Results: The results showed that treatments had significant effects on studied traits, as the highest plant height (36.5 cm) in treatment of bio-superphosphate application, the highest dry weight of plant (7.66 g plant-1) and nitrogen percent in leaf (2.06%) in integrated treatment of nitroxin and bio-superphosphate and the highest herb yield (653.2 kg.ha-1), essential oil content (0.44%) and essential oil yield (2.88 kg.ha-1) in treatment of vermicompost application were obtained. In an investigation of essential oil components, the highest citral content (58.33%) in in treatment of bio-superphosphate application and then treatment of vermicompost application (55.23%), the highest E-Caryophyllene content (4.37%) in treatment of vermicompost application and the highest Methyl chavicol content (43.17%) in chemical fertilizer were obtained.

Conclusion: In general, the results of this study showed, the application of organic and bio fertilizers, specially vermicompost in comparison to chemical fertilizer had a considerable role in increasing of yield and quantity and quality of essential oil of basil.
