ABSTRACT
Drought is one of the most important limiting factors for agricultural crops and vegetable
production all around the world. Potassium (K) is one of the vital elements required for plant
growth and physiology. So, the experiment was conducted at Sher-e-Bangla Agricultural
University, Sher-e-Bangla Nagar, Dhaka to determine effects of different dose of potassium in
drought condition on growth and yield contributing characters of different tomato varieties.
BARI Tomato 2, BARI Tomato 15 and BARI Tomato 16 were used in this experiment. Different
levels of potassium applied at drought condition. The treatments were T
1
(control), T
2
(0. 4g
K/pot + 200ml water/kg soil) and T
3
(0.9 g K/pot + 50 ml water/kg soil) applied at
vegetative(40days), flowering (64 days) and fruiting stage (78 days) days after transplanting
(DAT). The two factors experiment was laid out in Randomized Complete Block Design
(RCBD) with 3 replications. The morphological growth, physiological and yield components of
BARI tomato 15 showed the best performance with T
2
(0.4g K/Pot+200ml water/kg soil)
treatment combination, then BARI Tomato 2 and BARI tomato 16. The lowest yield was showed
in T
3
(0.9g K/Pot+50ml water/kg soil) treatment combination.
