A master’s thesis at the College of Agriculture on the effect of adding fulvic acid and spraying with pyridoxine on the growth and flowering of chrysanthemum plants.
The College of Agriculture at the University of Diyala discussed a master’s thesis entitled “The Effect of Adding Fulvic Acid and Spraying with Pyridoxine on the Growth and Flowering of Chrysanthemum Plants.” The study, presented by the student Suad Ibrahim Khalil Aswad, aimed to investigate the impact of spraying various concentrations of fulvic acid and pyridoxine on improving the vegetative and floral growth of chrysanthemum plants. It also sought to identify the optimal combination of concentrations between the two factors to enhance the growth and quality of chrysanthemum flowers.
The study explored the effects of fulvic acid at concentrations of 0, 0.5, 1.0, and 1.5 g/L, along with foliar spraying of pyridoxine (vitamin B6) at concentrations of 0, 50, 100, and 150 mg/L on the growth and flowering of Dendranthema grandiflorum Ramat, cultivar Morgana.
Several conclusions were reached:
-
Increasing the concentration of pyridoxine spray had a significant positive effect on most of the studied vegetative and floral traits, with 150 mg/L proving the most effective.
-
Likewise, raising the concentration of fulvic acid led to noticeable improvements in all vegetative and floral characteristics, with 1.5 g/L yielding the best results.
-
The most beneficial interaction occurred between spraying with 150 mg/L of pyridoxine and 1.5 g/L of fulvic acid.
The study recommends:
-
Spraying chrysanthemum plants with 150 mg/L of pyridoxine and 1.5 g/L of fulvic acid to enhance vegetative growth.
-
Conducting further research on the effects of pyridoxine and fulvic acid on various ornamental plants and cultivars to determine their influence on vegetative and floral growth.
