Effect of Inoculation with Bacterial and Fungal Biofertilizers on Growth and Flowering of Lilium spp. using Alternative Irrigation Salinized Water

This experiment was conducted in a greenhouse at Janat Al-Nakheel company located in khazmiah/Baghdad from 1/9/2020 to 1/6/2021 and aimed to study the effect of inoculation with fungal and bacterial biofertilizers on the growth and flowering of Lilium spp. under the influence of alternating irrigation with salt water. The experiment was implemented as a factorial experiment using the RCBD randomized complete block design with two factors, the first factor included inoculation with biofertilizers, while the second factor included alternating irrigation with saline water and the interaction between them. The results showed that the interaction between biofertilizers and tap water gave the highest recordings of vegetative and flowering growth in terms of plant height (48.63) cm, stem diameter (9.9) mm, leaf area (878.0) mm, concentration of proline in leaves (2.06) and peroxidase enzyme activity (6.95) The content of MDA leaves (0.531), flowering period (31.17) days, flower diameter (16.75) cm, number of flower buds (9.5) flower bud, carotene pigment concentration in flowers (3.027) and flowering age (22.00) days, as well as root length (22.03) cm and the percentage of dry matter in the roots (12.45)%.
