Salinity influenced the growth and yield of crops. Effects of GSH-rich nano fertilizer to reduce salinity stress remained unknown. The objectives of this study were to determine the effects of GSH-rich nano fertilizer on morphophysiological parameters of sweet corn plant and to compare the effectiveness between GSH-rich nano fertilizer and inorganic fertilizer. Seeds of sweet corn were grown in pots under different treatments of glutathione (GSH), sodium chloride (NaCl) and nano fertilizer. A Complete randomized design was used with three replicates. Treatments significantly affected morphophysiological parameters of corn plant (p˂0.05). Treatment of nano fertilizer with GSH significantly increased morphophysiological parameters of sweet corn than that of plants treated without GSH with nano fertilizer under salinity condition. In addition, nano fertilizer showed significant results in increasing morphophysiological parameter over commercial inorganic fertilizer. This study indicated that GSH enhanced physiological functions corn plants under nano fertilizer to lessen salinity condition.
