A pot experiment was conducted in the Net House of “Field Laboratory of Plant Stress Management” in the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka, during the period from October 2016 to March 2017. The two factors experiment was laid out in Complete Randomized Design with five replications. Factor A is three tomato varieties viz. V1= Exotic line 1 (Korean), V2= Exotic line 2 (Taiwan) and V3= BARI tomato 14 and factor B is seed priming treatment viz. P0= No priming (Control), P1= Hydropriming (distilled water), P2= NaCl priming (50 mM) and P3= KNO3 priming (200 mM). The total treatment combinations were (4×3) 12 and 8 dS/m fixed salinity maintained for all the pots. The experimental results exhibited that seed priming treatment significantly affected growth, yield and quality parameters of tomato. The highest plant height (137.10 cm), number of fruits per plant (40.92) and fruit yield per plant (585.00 g) were found from V1 under 8 dS/m salinity level. In case of seed priming, the highest plant height (150.10 cm), number of fruits per plant (48.11) and fruit yield per plant (755.80 g) were recorded from P2 mostly at 8 dS/m salinity level. Regarding the combined effect, the highest plant height (187.00 cm), number of fruits per plant (55.00) and fruit yield per plant (829.30 g) were found from V1P2 under 8 dS/m salinity level. So, Exotic line 1 with NaCl priming (50mM) showed better performance for growth, yield and quality of tomato under saline condition.
