EFFECT OF POTASSIUM AND EARTHING UP ON GROWTH, YIELD AND ECONOMIC BENEFIT OF CARROT
(DEPARTMENT OF HORTICULTURE, 2020) RIMA, SHARMIN SULTANA
The experiment was conducted in the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh. The experiment consisted of two factors. Factor A: Different levels of potassium as K 0 = Control, K 1 II = 100 kg K/ha, K 2 = 120 kg K/ha, K 3 = 140 kg K/ha and Factor B: E 0 = no earthing up, E 1 = two times earthing up, E 2 = three times earthing up. The experiment was laid out in a Randomized Complete Block Design with three replications. The collected data were statistically analyzed. Results revealed that in terms of potassium application, the highest gross yield of roots/ha (38.35 t) and marketable yield of roots/ha (35.32 t) were recorded from the application of K 2 (120 kg K/ha) treatment compared to K 0 (control) treatment. Again, in terms of different earthing up treatments, the highest gross yield of roots/ha (35.71 t) and marketable yield of roots/ha (34.75 t) were found from the treatment E 2 (three times earthing up) compared to E 0 (no earthing up) treatment. Both potassium and earthing up and their combination showed significant variation on different parameters of carrot. The highest gross yield of roots/ha (43.51 t) and marketable yield of roots/ha (42.29 t) were found from the treatment combination of K 2 E 2 (120 kg K/ha + three times earthing up) compared to K 0 E 0 (control) treatment combination. The highest gross return (Tk. 507480), net return (Tk. 313782) and BCR (2.62) were obtained from the treatment combination K 2 E 2 (120 kg K/ha + three times earthing up) where the lowest gross return (Tk. 240360), net return (Tk. 83478) and BCR (1.53) were obtained from K 0 (control) treatment combination. So, It can be concluded that 120 kg K/ha with three times earthing up was the best for carrot cultivation.
