Thin roots with uniform size from top to bottom are preferred for slicing and canning throughout the world. Nantes-type carrots are characterized by their cylindrical shape and nearly same diameter from end to end. The ability of GA₃ to alter root diameter and hence increase its suitability for slicing was studied in carrot cv. Nantes over the course of two consecutive growing seasons during 2021-22 and 2022-23 at Dr Yashwant Singh Parmar University of Horticulture and Forestry Nauni, Solan, Himachal Pradesh. Three concentrations of GA₃ i.e. 100, 150 and 200 ppm were sprayed onto 6 week old carrot seedlings. GA₃ sprays applied to carrot plants stimulated shoot growth and inhibited root growth. Maximum reduction in root diameter and root weight was observed in carrot plants sprayed with 200 ppm GA₃ but the reduction in root size was up to a point where they were still suitable for processing and slicing.
