Abstract:
The experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka
during October 2019 to February 2020 to find out the effects of plant growth
regulators on tomato growth, yield and quality when subjected to drought stress.
Two varieties of tomato namely BARI Tomato 2 and BARI Tomato14 were used
in this experiment. The treatments i.e. T
= Control (No water stress),
T

=Drought stress, T

=Drought + 100 ppm Indole Acetic Acid (IAA), T
=Drought + 100 ppm Abscisic Acid (ABA), T
= Drought + 100 ppm Salicylic
Acid (SA) were used in this experiment. Twenty five days old, healthy and
uniform seedlings were transplanted in plastic pot. Ten days after transplanting
drought was imposed for three weeks. Ten days after transplanting treatments
were also applied by hand sprayer. Three weeks after drought stress the plants
were rewatered again. The results indicated that drought stress significantly
reduced morphological, yield and quality parameters of tomato. The plant growth
regulators effectively reduced the effects of drought stress. Among the plant
growth regulators, IAA is the most suitable for mitigating drought stress and
maintaining tomato growth, yield and fruit quality.
