Abstract
The
experiment was conducted at the Horticulture Farm of Sher-e-Bangla
Agricultural University, Dhaka to evaluate the effect of phosphorus
and potassium on the growth and yield of carrot during the period
from November 2013 to March 2014. The two-factor experiment was
laid out in a Randomized Complete Block Design with three
replications. The experiment consisted of four different levels of
phosphorus, viz. P0 (control), P1 (65 kg), P2 (80 kg), and P3 (95 kg)
P2O5 ha-1 respectively and four levels of potassium, viz. K0
(control), K1 (150 kg), K2 (175 kg) and K3 (200 kg) K2O ha-1
respectively. Application of phosphorus and potassium influenced
independently and also in combination on the growth and yield of
carrot. The highest root length (16.27 cm), dry matter content of
root (9.31%), gross yield (38.37t ha-1) and marketable yield (36.03t
ha-1) was obtained from P3 (95 kg P2O5t ha-1) whereas, the control
treatment gave the lowest results. On the other hand, treatment K3
(200 kg K2O ha-1) performed the highest root length (16.78 cm), dry
matter content of root (9.35%), gross yield (42.22t ha-1) and
marketable yield (38.33t ha-1) and the control treatment showed the
lowest results. Considering the combined effect of phosphorus and
potassium, P3K3 (95 kg P2O5 ha-1 with 200 kg K2O ha-1) produced the
highest gross yield (40.58 t ha-1) and marketable yield (37.14 t
ha-1). The lowest gross (24.00 t ha-1) and marketable yield (22.24 t
ha-1) was produced by the control treatments combination (P0K0).
