| Title : | INVESTIGATING THE EFFECT OF ARBUSCULAR MYCORRHIZA GLOMUS Sp. AS A BIOFERTILIZER ON LETTUCE PRODUCTION |
| Abstract : | Arbuscular mycorrhiza used recently as biopesticide has shown beneficial effects on plant growth. An experiment was conducted in West Bekaa in 2016 in order to investigate the effect of a commercial biostimulant (MYCOSAT) containing 5 Glomus species on the production of two lettuce varieties: Romaine and Iceberg. Plant growth and nutritional quality were compared between mycorrhizal plants (mycorrhizal Romaine: MR and mycorrhizal Iceberg: MI) and non-mycorrhizal plants (non-mycorrhizal Romaine: NMR and non-mycorrhizal Iceberg: NMI). Measurements were done on root and leaf parameters and results showed a significant positive effect of mycorrhizal inoculation on plant growth. Best results were obtained for root parameters as well as leaf area and leaf weight in mycorrhizal plants of both varieties compared to non-mycorrhizal plants. An improvement was found in root length, root diameter, number of secondary roots and root weight by 81%, 81%, 61% and 60% for MR plants and of 80%, 88%, 84% and 94% in MR and MI in comparison to NMR and NMI. Leaf number was only enhanced in MI plants. The improved crop performance was associated with an ameliorated nutritional status with higher percentages of N, P, and K in leaves and was correlated to a stronger root development in mycorrhizal plants due to the action of arbuscular mycorrhiza. Finally, the application of the biostimulant MYCOSAT could provide a biological tool for improvement of growth and quality of lettuce grown in clay soils of West-Bekaa. |
