A pot experiment was carried out at Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka May to September, 2016 to evaluate the performance of summer tomato production with the supplementation of salicylic acid (SA) and calcium (Ca). The experiment consisted of two factor. Four different levels of SA (S₁ = 0 mM SA, S₂ = 0.3 mM SA, S₃ = 0.6 mM SA, S₄ = 0.8 mM SA) and three levels of Ca (C₁ = 0 mM Ca, C₂ = 4 mM Ca, C₃ = 8 mM Ca). Both morphological traits and yield of summer tomatoes were significantly affected by the application of SA and Ca. Exogenous application of SA and Ca influenced the growth including plant height, leaf number, branch number, yield contributing characters and yield. The combined supplementation of 0.8 mM SA and 8 mM Ca resulted the highest yields (0.8 kg/plant) where lowest one (0.3 kg/plant) was recorded from the control treatment (without SA and Ca). These results suggest that SA and Ca can improve the growth and yield of tomatoes during the summer season by alleviating the detrimental effects of extreme heat in the summer.
