Overview (resum en anglès): Most cultivated horticultural species are potential hosts for arbuscular mycorrhizal fungi. These fungi develop inside the roots of plants and establish a mutualistic symbiotic relationship that allows greater tolerance to water and salt stress for the plant.
This project is part of a Technology Transfer Demonstration Activity, funded through Operation 01.02.01 Technology Transfer of the Rural Development Program of Catalonia 2014-2020. This activity aims to demonstrate the reduction of fertilizers and water thanks to inoculation with mycorrhizal fungi in vegetable crops. The activities took place at the IRTA facilities in Cabrils (Barcelona). The trial of this work has been the fourth crop of a rotation of leeks, zucchini and beans. The species used was celery (Apium graveolens) and two mycorrhizal inocula - IRTA inoculum and commercial inoculum - compared to non-mycorrhizal plants. The response of mycorrhizal plants in conditions of lower availability of water and fertilizers and their impact on production and quality have been studied.
In general, there are no significant differences between control and mycorrhizal treatments in terms of fresh weight and dry weight of aerial part, water content of leaves and dry weight of root. There are significant differences in mycorrhizal treatments between optimal irrigation and deficit irrigation for the different parameters analysed. Biomass indices show that in deficit irrigation the plants have invested in greater root development, but yield (fresh commercial weight of the aerial part) has been lower than in optimal irrigation. Mycorrhizal treatments do not show an increase in celery production. Mycorrhizae have not caused any significant difference in the nutrient content of the soil after celery cultivation, nor in the area of optimal fertigation, nor in the area where 25% less has been fertilized.
