Abstract:
The experiment was conducted at the experimental field of Sher-e-Bangla Agricultural
University during the period from December 2021 to April 2022 under the AEZ 28
(Madhupur tract), to assess effects of different levels and different sources of P on
yield of tomato. The experiment comprised a single factor comprising seven treatments
viz. T
0
P
0
(P control); T
1
(from DAP); T
5
P
60
P
20
(from TSP); T
2
(from TSP); T
6
P
60
ii
P
20
(from DAP); T
3
P
40
(from TSP); T
4
(from DAP). This experiment was laid out in a
randomized complete block design
(RCBD) with three (3) replications. Data were collected on
different aspects of growth and yield attributes of tomato including soil properties and nutrient
contents. The results
revealed that treatment T
5
, T
4
, and T
6
respectively exhibited its
superiority compared to other treatments in terms of fruit yield of tomato. The maximum plant
height (56.17 cm) was observed
at T
4
. At 70 DAT, the longest plant (144.45 cm) was
recorded from the T
3
treatment. The maximum number of leaves plant
-1
(153.33) was recorded
from the T
6 treatment. At 70 DAT, the maximum number of branches plant
(15.00) was
recorded from the treatment T
5
. The maximum number of leaf branches
-1
(17.67) was recorded
from the T
5
treatment. The maximum number of fruits plant
-1
-1
(41.00) was observed at T
6
. The
fruit’s dry weight ranged from 79.29 g to
115.63 g. All the observed fruit dry weights were
statistically similar. The maximum
fruit yield plant
-1
(4.13 kg, 3.86 kg, and 3.79 kg) was
observed at T
5
, T
4
, and T
6 respectively. In the case of soil properties, the highest organic carbon
(0.85%)
was noted in treatments T
4
and T
5
. Both are statistically similar, and the maximum
soil pH (6.32, 6.24, and 6.17) was recorded in T
2
, T
1
, and T
0
treatments respectively in
postharvest
soil.
Considering
the
soil
nutrients,
the
highest
available
P
content
in
soil
(23.0
ppm)
was
recorded
in
the
T
5
treatment and the maximum potassium content in soil (0.129 meq. /100
g soil) was recorded from the treatment T
5.
