Abstract
This research was conducted to learn whether or not mustard may benefit from exogenously administered KH2PO4 to alleviate salt stress (Brassica campestris). The one-plant/pot experiment was carried out in the field. The plants were split into eight groups after 30 days. i.e., A: Control (without salt and KH2PO4) B: Plants irrigated with 60 mM salt and without KH2PO4, C: Plants irrigated with 80 mM salt and without KH2PO4, D: Plants irrigated with 100 mM salt and without KH2PO4, E: Plant treated with 0.5 M KH2PO4 alone, F: with 0.5 M KH2PO4 and 60 mM salt, G: with 0.5 M KH2PO4 and 80 mM salt, H: with 0.5 M KH2PO4 and 100 mM salt. Current findings showed that all development and metabolic indicators were significantly impacted by salt. However, a 0.5 mM KH2PO4 treatment was particularly effective in growth enhancing and mitigating the salt stress negative effects. KH2PO4 is known as the stimulator of seed germination, absorption of water and also operate as a signaling molecule working under the saline circumstances, all of which may account for the growth enhancement seen in its presence. According to the results of this research, there is at least a chance that low to medium concentrations of KH2PO4 might end up being extremely useful in the future for boosting the development and yield of plants cultivated in environments with high levels of salt stress.
