Response of Coriander Plants to Some Organic and Bio-Fertilizer Treatments

Abstract

This investigation was conducted during two experimental seasons of 2020/2022 to explore the impact of fertilization (farmyard manure at rats 0, 10, 15 and 20 m³/fed., plus half-recommended dose of NPK fertilizer) and biofertilizers (seed inoculation with a mixture of bacteria; A. chroococcum, B. megatherium var. phosphaticum, B. circulas and/or arbuscular mycorrhizae fungi), as well as their interactions on growth, yield, and volatile oil of coriander plants. Results showed a significant increase in plant growth traits i.e., plant height, number of branches, plant fresh and dry weight, yield components i.e., number of capsules per plant, seed yield per plant and per feddan, as well as volatile oil production. Treating plants with a high rate of farmyard manure registered the highest values of these studied characteristics. Also, adding a mixture of bacteria; A. chroococcum, B. megatherium var. phosphaticum, B. circulars with arbuscular mycorrhizae fungi proved to be more effective in augmenting the previously studied traits. All tested parameters were significantly affected by the interaction treatments. In this concern, most combined treatments significantly augmented all examined aspects. Moreover, the addition of farmyard manure at a high level plus inoculation coriander seeds mixed with bacteria and mycorrhizae fungi were the most effective treatments. Generally, the combination of farmyard manure at a high rate plus inoculation of seeds by mixed bacteria and mycorrhizae fungi increased percentages of main components of volatile oil compared to untreated plants.
