Abstract

The growth and production of carrot influenced by macronutrients and harvesting time, thus a field experiment was conducted at Horticultural Research Field of Sher-e-Bangla Agricultural University, Dhaka, between December 2020 and March 2021 during the Rabi season to evaluate the response of carrot to different macro nutrients and harvesting time. The experiment consisted of two factors i.e., macro nutrients and harvesting time, and laid out using Randomized Complete Block Design (RCBD) with three replications. Factor A: Different levels of macronutrients (4) i.e., F0= Control, F1= N160P50K120S30 kg ha-1, F2 = N185P70K140S40 kg ha-1, F3 = N210P90K160S50 kg ha-1 and Factor B: A Harvesting time (3) i.e., H1 = 90 days after sowing, H2 = 100 days after sowing and H3 = 110 days after sowing. Experimental results revealed that different levels of macronutrients and harvesting time significantly influenced the growth and yield of carrot. In case of combination treatment (macro nutrients and harvesting time) the highest brix percentage of carrot root (8.20 %), marketable root yield per plot of carrot (6.40 kg) and marketable root yield of carrots per hectare (26.67 t) were observed in the F2H2 treatment combination comparable to others treatment combinations. Therefore, it was suggested that cultivation of carrot through application of fertilizer @ N185P70K140S40 kg ha-1 (F2) and harvesting at 100 days after sowing (H2), appeared to be best for achieving higher growth, yield and quality root of carrot.
