Abstract:
Salt stress, resulting from increased soil salinity, poses a significant threat to agricultural
productivity worldwide, including the growth and development of moringa plants.
Understanding the responses of moringa to salt stress is crucial for developing effective
strategies to mitigate the negative effects and improve plant resilience. A polybag
experiment was conducted at the agroforestry farm of Sher-e-Bangla Agricultural
University, Dhaka during May 2022 to August 2022 to examine the establishment of
Moringa seedling under salt stress. This was a single factor experiment: Salinity. The
factor had six (6) different levels of salinity i.e. T

. The experiment was laid out on
Completely Randomized Design (CRD) with six replications. Our results revealed that T

showed the best performance regarding germination percentage (93.33%), plant height
(68.70 cm), number of leaves plant

(262.70), shoot length (56.5 cm), root length (12.20
cm), total fresh weight (14.84 g), shoot fresh weight (9.10), root fresh weight (5.7), total
dry weight (2.10 g), shoot dry weight (1.46 g) and root dry weight (0.64 g). On the other
hand, the least performance regarding germination percentage (0%) from T

. The growth
performance was decreased with the increasing levels of salinity; (T

) which
further affect seed germination and seedling establishment of Moringa oleifera.
