Abstract:
Drought is a severe limiting factor for vegetable production. So, a pot experiment was
conducted in the field laboratory of the Department of Agroforestry and
Environmental Science, Sher-e-Bangla Agricultural University, from October 2018 to
February 2019 to observe the performances of four tomato varieties (BARI Tomato 2,
14, 15 and 16) under three different drought treatments (irrigation interval: 1 daycontrol,
3 days-mild and 5 days-severe drought) in completely randomized design
with three replications. The results showed significant negative influence of drought
which decreased plant height, leaf number, stem diameter, SPAD value, growth rate,
fresh and dry weight etc. resulting yield loss. Under mild drought, yield plant
decreased by 32, 8, 14 and 20% where under severe drought, it decreased by 35, 52,
47 and 51% in BARI Tomato 2, 14, 15 and 16, respectively. So, BARI tomato 14 is
the best variety under mild and BARI tomato 2 under severe stress condition.
