Effect of bio-fertilizer and spraying of nano-fertilizer and gibberellin on the chemical traits of Aloe vera L.

A factorial experiment with three replications was conducted according to a randomized complete block design (RCBD) to study the effect of bio fertilization at three levels (0, Azotobacter, Mycorrhizae) and spraying with nano fertilizer (Nano Iron) (0, 1500, 3000) mg L-1 and gibberellin GA3 (0, 150) (300) mg L-1 in the chemical traits of Aloe vera L.) in lath house of the Department of Plant Production Techniques / Al-Musayyib Technical College / Middle Euphrates University during the 2021-2022 agricultural season. After the experiment ended, the results were: The treatments of adding azotobacter and spraying with nano iron concentration of 3000 mg L and gibberellin concentration of 300 mg L-1 were significantly superior in all studied traits. It was also caused by the bi-interaction (Mycorrhizal + Nano iron 3000 mg L-1), (Mycorrhizal + gibberellin 300 mg L-1) and (Mycorrhizal iron 3000 mg L-1 + Gibberellin 300 mg L-1) and the triple interaction between the study factors (Mycorrhizalgia). + Nano iron 3000 mg L-1 + gibberellin 300 mg L-1) a significant increase in most of the studied traits Keywords: Rheumatoid arthritis, Tripartite motif-containing protein 72, Disease activity score 28.
