Abstract:

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