Abstract
Background: Salinity is one of the most pervasive abiotic stresses affecting agricultural productivity worldwide. Mung bean, a salt-sensitive crop, is particularly impacted by salt stress, which hinders its development. Salicylic acid (SA), a vital plant hormone, offers a significant agronomic advantage by enhancing crop tolerance to salt. Potassium nitrate, a source of potassium, is an essential nutrient that improves plant resilience against various stresses, including salinity. Methods: An experiment was conducted at the Student Instructional Farm at ANDUAT, Ayodhya, during Kharif 2021 and Kharif 2022 to study the physiological role of salicylic acid and potassium nitrate in mitigating salinity stress in mung bean (V. radiata). The experiments consist of seven treatments, including untreated control and evaluated biochemical parameters (chlorophyll content, total protein content, peroxidase content, proline content and nitrate reductase activity), morphological parameters (plant height, number of branches per plant), total dry biomass, relative water content (RWC%) and yield components (number of pods per plant, seeds per pod, clusters per plant and seed yield (q per ha). Result: The results showed that the highest plant height, number of branches per plant, total dry biomass, proline content, nitrate reductase activity, number of pods per plant, number of seeds per pod, number of clusters per plant and seed yield per plant were observed at salicylic acid @150 ppm. The maximum seed yield per ha was observed at salicylic acid @100 ppm. On contrast, maximum plant height, peroxidase activity, total dry biomass, proline content, nitrate reductase activity, number of seeds per pod, number of clusters per plant and seed yield per plant were observed at potassium nitrate @ 400 ppm.
