Abstract: Plant growth regulators (PGR) at low concentrations may play an important role in increasing vegetable crop production, especially with the possibility of reducing fertilizer costs through foliar application. To produce turnips of good quality and economical yield, this study aimed to evaluate the use of foliar application with plant growth regulator Biozyme-TF at 0, 3 and 6 mL L-1 and the foliar organic Taravert Evo at 0, 2 and 4 mL L-1 on turnip vegetative growth and root quality characteristics. The experiment was a two-factor RCBD (randomized complete block design) with five replicates. Overall, the results indicate that the values of the measured parameters increasedsignificantly with increasing Biozyme-TF concentration, remarkably at 6 mL L-1 compared to the lower concentration and the control. Foliar organic fertilizer Taravert Evo at 4 mL L-1 recorded significantly higher vegetative growth parameters than those recorded when using the lower concentration of 2 mL L-1. However, the two concentrations did not differ much in their effect on the root qualitative traits, but they resulted in values significantly different from the untreated control. The highest values for all parameters, plant height, number of leaves, shoot fresh weight, shoot dry weight, leaf area, total leaf chlorophyll content, root length, root circumference, root diameter, rootmorphology index, root fresh weight and root dry weight were obtained in the interaction treatment of 6 mL L-1. Biozyme-TF in the presence of 2 or 4 mL L-1 Taravert Evo foliar fertilizer, with significant differences (p ≤ 0.05) compared to all individual treatments and the untreated control. The study confirms the possibility of producing high-quality turnips using economically low costs foliar nutrient-rich organic fertilizer, especially in combination with relatively low concentration of foliar PGR.
