Abstract
The use of biogtimulants for promoting plant growth like bacteria and plant extracts have great potential to provide economical and sustainable solutions to current agricultural practices and challenges .Two consecutive field trials in 2019 and 2020 were conducted to investigate the effect of foliar spraying by Moringa extract and pink-pigmented methylotrophic bacteria on growth and on essential oil content of Calendula officinalis plant. Four concentrations of Moringa extract (1.0, 2.0, 4.0 and 6.0 %) and four concentrations of pink-pigmented methylotrophic bacteria (0.5, 1.0, 2.0 and 3.0 %) were used. All Moringa and pink-pigmented methylotrophic bacteria treatments positively impacted growth characters, viz. plant height, number of herb leaves and essential oil contents seasons in both two seasons studied. Plants sprayed with 2.0% moringa extract produced the highest plant hight and number of herb leaves and when sprayed with 4.0% moringa extract it increased essential oil contentes (ml/plant) Also, essential oil contents (as percentage) increased when plants were sprayed with 2% pink-pigmented methylotrophic bacteria. Key words: Moringa extract, Growth, Essential oil,Pink-Pigmented Methylotrophic Bacteria, Calendula officinalis , pot marigold.
