Abstract:
The present experiment was carried out at the Farm of Sher-e-Bangla
Agricultural University, Dhaka-1207 to find out the effect of liming and
phosphorus on growth and yield of tomato during the pried from October 2014
to April, 2015. The experiment consisted of four level of phosphorus viz. 0, 20,
40, 60 kg P ha
-1
and three levels of dolomite (viz. 0, 1, 1.5 t ha
) as liming
material. The two factors experiment was set up in Randomized Complete Block
Design (RCBD) with three replications. In total, there were 12 treatment
combinations in this study. A unit plot was 2m×2m and the treatments were
distributed randomly in each block. Data on growth and yield parameters were
recorded and analyzed statistically. Results showed that different levels of
phosphorus and liming significantly differed in all growth and yield
contributing characters. The highest plant height (85.26 cm), number of primary
branches (13.65), fruit length (6.82 cm) and yield of fruit (66.29 t ha
) was
obtained from 60 kg P ha
-1
treatment. The maximum plant height (85.02 cm),
number of primary branches (12.40), fruit length (6.77 cm) and yield of fruit
(55.18 t ha
-1
) was recorded from 1.5 ton dolomite ha
-1
. The highest plant height
(91.24 cm), number of primary branches (15.03), fruit length (8.20 cm) and yield
of fruit (82.55 t ha
1
+ 1.5 t ha
-1
-1
-1
) was recorded with the treatment combination of 60 kg P ha
of dolomite
.
On the other hand, the lowest yield of fruit (24.4 t ha
)
and for all cases lowest result was found in no phosphorus and no liming. The
highest N, P and K concentration in soil was recorded from 60 kg P ha
treatment. The highest N, P and K concentration in soil was recorded from 1.5
ton dolomite ha
-1
treatment. The highest N, P and K concentration in soil was
recorded from 60 kg P ha
-1
with 1.5 ton dolomite ha
-1
treatment.
