Indole-3-Butyric Acid (IBA) is a cornerstone in plant propagation and growth enhancement, but its effectiveness is highly dependent on the correct concentration. Different plant species and even different types of cuttings within the same species can respond differently to IBA applications. Therefore, understanding the nuances of IBA concentrations is crucial for maximizing rooting success and promoting optimal plant growth.

The application of IBA typically involves dissolving the powder in water or a solvent to create a solution. The recommended concentration ranges vary widely, from as low as 5-20 ppm for soaking grape cuttings to 1000-2000 ppm for a brief soak of fruit tree cuttings. For general application on rice or wheat during budding, concentrations of 10 ppm are often sufficient to promote rooting and increase yield. For solanaceous vegetables, a concentration of 250 ppm applied to flowers can encourage parthenogenesis and improve fruit setting.

When using IBA for plant rooting, it's important to consider the type of cutting. Softwood cuttings generally require lower concentrations than semi-hardwood or hardwood cuttings. The duration of exposure to the IBA solution also plays a critical role; shorter dips at higher concentrations are common for more recalcitrant species, while longer soaking periods at lower concentrations might be used for easier-to-root plants. This careful calibration ensures that the plant receives the optimal hormonal signal for root initiation without causing damage.

For fruit setting and growth regulation in vegetables, lower concentrations like 250 ppm can be applied via spraying or soaking the flowers. This stimulates the development of parthenocarpic fruits (fruits that develop without fertilization) and can significantly increase the fruit setting rate. It is also noted that IBA can be effectively combined with foliar fertilizers at concentrations of 5-15 ppm for overall plant health improvement.
