Effect of Spacing and Sowing Time on Growth and Yield of Carrot (Daucus carrota L.)

An investigation was carried out at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka during the period from November 2005 to April 2006 to determine the growth and yield of carrot as influenced by different sowing dates and spacing. The study was conducted with four sowing times of carrot viz. 28 November (T ), 8 December (T ), 18 December (T ) and 28 December (T ) having three spacings viz. 20cm 12 3 4 x 10cm (S ), 25cm x 15cm (S ) and 30cm x 20cm (S ). Leaf length, root length, leaf fresh weight, root fresh weight, 12 3 root diameter, leaf dry weight and root dry weight were significantly differed among the sowing times at different spacings. The maximum root length (14.82 cm), root diameter (20.39 cm), root fresh weight (217.4 g plant ) and root dry weight (32.47 g plant ) were found in T S and the minimum of these parameters were 11 13 found in T S. The percentage of cracking root and branched root of carrot was lower in T S followed to others 41 11 and it was gradually increased due to delay sowing.
