Carrot (Daucus carota L.) with chromosome number (2n) = 18 and belonging to the family Umbelliferaeis one of the important root vegetable crops. In India, root to seed is the standard method for the production of high quality seed as this method allows for the selection of healthy and true to type roots for the planting of stecklings. If the seed quality is not good, it may again be difficult to get enough number of uniform roots. This study was conducted at Seed Research Area of Department of Vegetable Science, Chaudhary Charan Singh Haryana Agricultural University, Hisar during spring-summer season of 2018-19. The experiment comprised five treatments of plant spacing (60 x 30 cm (Flat), 60 x 45 cm (Flat), 60 x 60 cm (Flat), 60 x 30 cm (Single row on ridge), 60 x 45 cm (Paired row on ridge) and three steckling size (8 cm, 6 cm and 4 cm) was laid out in Randomized Block Design with three replications. Number of branches per plant and number of secondary umbels per plant was found maximum with plant spacing of 60 x 60 cm (Flat) at final harvest. However, maximum number of branches and number of secondary umbels per plant were found at steckling size of 8 cm which was found to be at par with steckling size of 6 cm.
