Abstract

The experiment was conducted in the fields of the Technical College / Musayyib during the winter season of 2019- 2020. The experiment was applied according to the arrangement of the split plots and the transactions were distributed using the Randomized Complete Block Designs and in three sectors, the planting dates represented 25/10 - 10/11 - 25/11 Main plots As for the sub plots, the sub plots included the concentrations of thiamine, ascorbic acid (100 ppm and 200 ppm) and ascorbic acid (50 ppm and 100 ppm), and the control treatment was spraying with distilled water only. The results of the statistical analysis of the data showed: 1. The first date was superior to the plant height, number of leaves, number of branches, and dry and wet weight, while the third date excelled the number of leaves in the first season. 2. The concentration of 200 ppm of thiamine gave a significant superiority in the traits of plant height, number of leaves, number of branches, dry and wet weight. 3. The concentration of 100ppm of ascorbic acid gave a significantly excelled in the characteristics of plant height, number of leaves, number of branches, dry and wet weight. 4. As for the interaction between dates and concentrations, the first date with a concentration of thiamine excelled 200ppm, and the interaction between the first date and second concentration of ascorbic acid excelled 50ppm in the traits of plant height, number of leaves, number of branches, dry and fresh weight.
