The impact of auxin on the vegetative and reproductive growth of carrot (Dacus carota L.)

Seed is a basic component of every crop species and quality seed essential for farmers to achieve greater production higher yields. yield can be improved by using the growth hormones. Indole-3-butyric acid (IBA) IBAplays vital role in reproductive development plant. An investigation being conducted determine effect rooting hormone IBA on that leads developement. Roots treated with three levels (500 ppm, 1000 ppm 1500ppm) along control 3 replication. Results showed roots @ 1500 had taken least number (28.4) days flowering maximum plant height (34.3cm), leaves (15.3), length (19.6 cm), secondary (10) tertiary umbels (13.7), diameter (12.7 cm) umbel (4.4), weight (5.1 g) (3.5), (4.4 (1.5 biological plants (81.0 respectively. However, diameter, primary was good ppm. Thus it recommended application at concentration significantly improve carrot plants, hence increasing
