Abstract:
Soil salinity limits agricultural production significantly. A pot experiment was
conducted in the field laboratory of the Department of Agroforestry and
Environmental Science, Sher-e-Bangla Agricultural University, Dhaka- 1207, during
the months of October 2021 to April 2022 to observe the performances of
gibberellicacid [G0 (0 mg/L), G1 (50 mg/L), G2 (100 mg/L)] on the growth and yield
of tomato (BARI tomato 16) under salt stress [S0 (0 mM NaCl), S1 (50 mM NaCl)
and S2 (100 mM NaCl), S3 (150 mM NaCl) following completely randomized design
with three replications. Salinity stress hampered growth and productivity of tomato in
dose dependent manner. Salt stress primarily reduced leaf number and chlorophyll
pigments in leaf which consequently decreased the plant height as well as plant
biomass including fruit yield. But application of gibberellic acid could not alter the
saline induced damages. It drastically increased the plant height in both stressed and
non-stressed condition but deformed the fruits and destroy marketable yield.
