Effect of NaCl Salt on Vegetative Growth and Yield of Sixteen Tomato Lines

Abstract

An experiment was conducted at the Sher-e-Bangla Agricultural University, Bangladesh to evaluate influence of salt (NaCl) on sixteen tomato lines. Sixteen lines coded from V 1 (Line-01) to V 16 (Line-16) were executed under different NaCl salinity conditions (S 0 : Control; S 1 : 12dS/m and S 2 : 16 dS/m) following completely randomized design with three replications. Apart from control, V 8 provided tallest plant in 12 dS/m (43.7 cm) and in 16 dS/m (38.4 cm) salinity level at 60 days after transplanting which was statistically similar with the V 9 tomato line. V 8 line provided the maximum number of leaves per plant except control (24.2 and 21.1 in 12 dS/m and 16 dS/m respectively). V 9 line produced maximum leaf area (123.7 cm 2 and 97.6 cm 2 in 12dS/m and 16 dS/m respectively) under saline conditions which was followed by V 8 line (112.7 cm 2 and 92.6 cm 2 in 12dS/m and 16 dS/m respectively). Maximum number of bunch per plant was observed from V 9 line (10.7 and 9.3 in 12 dS/m and 16 dS/m respectively) followed by V 8 line (9.3 and 9.3 in 12 dS/m and 16 dS/m respectively) except control. Maximum yield was found from V 9 line (0.923 kg/plant) followed by V 2 line (0.493 kg/plant) in 12 dS/m salinity level and maximum yield was found fromV 9 line (0.593 kg/plant) which was closely followed by V 8 line (0.407 kg/plant) in 16 dS/m salinity level. Tomato line-09 was found the best tomato cultivar for salt affected areas in Bangladesh.
