Abstract:
The experiment was conducted at the research plot of the department of Soil
science of Sher-e-Bangla Agricultural University, Dhaka during the period
from February, 2014 to June, 2014 to study the influence of phosphorus and
potassium on growth and yield of mungbean. The experiment was designed
with three phosphorus level viz. P
and three different potassium level viz. K
0
(0 kg P/ha), P

(15 kg P/ha), P
(0 kg K/ha), K

(20 kg P/ha)
(15 kg K/ha) and K
(20 kg K/ha). The experiment was laid out in a two factors randomized
complete block design (RCBD) with three replications. Results showed that
different phosphorus and potassium levels significantly differed the growth
and yield contributing characters of mungbean. The maximum seed yield
(1.65 t ha

On the other hand, the lowest seed yield (0.95 t ha

concentration in stover and soil was recorded in the 20 kg P/ha treatment. The

kg K/ha treatment. The highest N, P and K concentration in stover and soil was
recorded in 20 kg P/ha with 20 kg K/ha treatment combination. Mungbean
yield was increased with increasing the P and K levels.
