Abstract:
A field experiment was conducted at Sher-e-Bangla Agricultural University Farm,
Dhaka in kharif-I season during the period from March 2016 to May 2016 to study
the effect of phosphorus on growth and yield of mungbean (BARI Mung-6) under
different row spacings . There were two factors viz. phosphorus and different row
spacings. Four phosphorus (p) levels viz. (i) P
= Control; recommended (R) dose
of phosphorus (48 kg P
2
O
5
ha
-1
), (ii) P
1
0
= 25% less than R dose; 36 kg P
,
(iii) P
2
= 25% more than R dose; 60 kg P
2
O
5
ha
-1
and (iv) P
= 50% more than R
dose; 72 kg P
2
O
5
ha
-1
. Three different row spacings viz. (i) S
3
1
= 20 cm, (ii) S
= 30
cm and (iii) S
= 40 cm. The experiment was laid out in a Randomized Complete
Block Design (RCBD) with three replication. In case of phosphorus levels, the
maximum seed yield (1.41 t ha
3
-1
) and maximum stover yield (1.67 t ha
) was
recorded from P
0
(48 kg P
2
O
5
ha
-1
) treatment which was statistically identical with
P
2
(60 kg P
2
O
5
ha
-1
) treatment and P
3
(72 kg P
2
O
5
ha
-1
) treatment. The minimum
seed yield (1.02 t ha
-1
) and minimum stover yield (1.28 t ha
-1
) was recorded from
P
1
(36 kg P
2
O
5
ha
-1
) treatment. In case of row spacing, the highest seed yield (1.42
t ha
-1
) and highest stover yield (1.73 t ha
-1
) was achieved by S
(30 cm) row
spacing. Whereas, the lowest seed yield (1.13 t ha
-1
2
2
) and stover yield (1.38 t ha
)
was achieved by S
(20 cm) row spacing. In case of combined effect the maximum
seed yield (1.57 t ha
1
-1
) and maximum stover yield (1.86 t ha
-1
) was recorded from
P
0
S
2
and minimum from P
1
S
. So, from the results it may be concluded that
application of phosphorous at the rate of 48 kg P
1
2
O
5
ha
-1
under a row spacing of 30
cm was found to be achieving higher yield of mungbean
