Among the abiotic stress, salinity is conceived as a detrimental environmental stress that impairs crop production worldwide. The pot experiment was conducted at the Agricultural research field of the IUBAT, Dhaka during the period from January to April ۲۰۲۲ to assess the impacts of different concentrations of salt on the growth and yield of okra. The experiment followed a completely randomized design with three replications. The growth and yield components exhibited significant variations across different treatment groups. This study reveals the intricate dynamics of plant growth, mortality, leaf number, flowering, fruit set, and fruit yield in response to a range of nitrobenzene and salinity treatments during different developmental stages. Notably, the control group (T۰) demonstrated remarkable resilience, particularly in later stages, compared to that of other treatments.
Nitrobenzene treatments initially showed growth-promoting potential, but this effect diminished over time, while salinity consistently hindered growth. Interestingly, the combined effect of nitrobenzene and salinity treatments revealed complex interactions, suggesting tailored strategies to optimize crop productivity. In addition, the timing of flowering and fruit setting proved to be sensitive to these treatments, highlighting the intricate relationships between salinity and nitrobenzene. The highest plant height (۱۴.۹۱ cm), and the maximum leaf length (۱۰.۰۸ cm) were observed in the T۰ (Control) treatment. The T۱۰
Salinity (۱۰۰ mM) +
Nitrobenzene (۲۰%) treatment exhibited the highest fruit number, with a count of ۱۴, while the T۲ (Nitrobenzene ۲۵%) and T۹
Salinity (۵۰mM) +
Nitrobenzene (۳۰%) treatments had the lowest fruit number, with only ۱ fruit each. The maximum fruit length was observed in the T۰ (Control) and T۱۳
Salinity (۱۵۰mM) +
Nitrobenzene (۲۰%) treatments during the first stage of harvesting, measuring ۷.۲ cm and ۷.۲۶ cm, respectively, while the T۱۳
Salinity (۱۵۰ mM) +
Nitrobenzene (۲۰%) treatment exhibited the highest yield of
okra (۹۱ g). The results obtained from the present study provide valuable insights into the morphological responses of Okra plants, paving the way for innovative approaches to crop management and optimizing yield under challenging environmental conditions.
