Abstract:
The field experiment was conducted at the experimental plot of Sher-e-Bangla
Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207 during the period from
September, 2019 to March, 2020 in Rabi season to find out the impact of different
planting time and nitrogen levels on growth and yield of tomato on rooftop
garden.BARI tomato-14, also known as „Sharabonti‟ was used as planting material in
this study. The experiment consisted of two factors: Factor A: Planting time (3 dates)
as i) P
1
– 1
st
October, 2019, ii) P
2
– 15
th
October, 2019 and iii) P
iii
3
– 1
November,
2019. and Factor B: Nitrogen management (4 levels) as i) N
- 0 kg ha⁻¹ (control), ii)
N
1
– 70 kg ha⁻¹, iii) N
2
– 120 kg ha⁻¹ and iv) N
3
0
– 170 kg ha⁻¹. The experiment was
laid out in a Randomized Complete Block Design (Factorial) with three (3)
replications. Different date of planting, varying level of nitrogen fertilizer and the
interaction effect showed significant difference on growth and yield parameters of
tomato.Transplanting tomato seedlings at 15
th
October (P
) showed the most
significant effect on the growth and yield of tomato. Application of 120 kg N ha⁻¹(N
2
)
had the maximum effect on the growth and yield of tomato. In case of interaction, the
highest result was obtained from P
2
N
2
(15
th
October planting with 120 kg N ha⁻¹
application) treatment combination. Application of 120 kg N ha⁻¹ on tomato plants
which were planted at 15
th
October seemed to be more suitable for getting higher
amount and quality fruit yield of tomato on rooftop garden.
