Aims: to evaluate the growth response of tomato to plant growing structures and media grown in the rooftop garden conditions.

Study Design: The factorial experiment was laid out in a Completely Randomized Design (CRD)

Place and Duration of Study: This experiment was carried out at the rooftop garden of the Department of Agricultural Botany, Sher-e-Bangla Agricultural University (SAU), Dhaka-1207, Bangladesh from October 2017 to March 2018.

Methodology: The experiment had two factors, factor A- two plant growing structures, viz., S₁= Plastic pot, S₂= Earthen pot and factor B- six different plant growing medium viz. M₀=Soil 100% (w/w) + inorganic fertilizer (IF)/(control), M₁=Soil 80% (w/w) + 20% cow dung (w/w) + IF, M₂=Soil 70% (w/w) + 30% cow dung (w/w) + IF, M₃=Soil 90% (w/w) + 10% vermicompost (w/w) + IF, M₄=Soil 80% (w/w) + 20% vermicompost (w/w) + IF, M₅=Soil 80% (w/w) + 10% cow dung (w/w) + 10% vermicompost (w/w) + IF.

Results: Considering plant growing structures, the plastic pot (S₁) gave the highest plant height, number of leaves per plant, branches per plant. The soil 80% (w/w) + 10% cow dung (w/w) + 10% vermicompost (w/w) + IF marked as (M₅) had the highest plant height, number of leaves per plant, branches per plant. The highest morphological data were obtained from the treatment combination of S₁M₅ (plastic pot along with the soil 80% (w/w) + 10% cow dung (w/w) + 10% vermicompost (w/w) + IF)).

Conclusion: On the basis of the  findings  in this study, it can  be  concluded that, plastic pot along with soil 80% (w/w) + 10% cow dung (w/w) + 10% vermicompost (w/w) + IF be able to increase the growth of BARI tomato14 for rabi season in the rooftop garden under the climatic conditions of SAU(Sher-e-Bangla Agricultural University).
