Role of humic acid and salicylic acid on quality parameters and K/Na ratio of Groundnut (Arachis hypogaea L.) under salt and water stress


Author(s): Sandeep Nigania, Yogesh Sharma and Bablesh Kumar

Abstract: A field experiment was conducted during kharif 2015-16 to study the response of groundnut to humic acid and salicylic acid under salt and water stress conditions. Results revealed that application of saline water (4.0 dS m-1) and water deficit irrigation (0.8 ETc) significantly decreased the quality parameters of groundnut such as oil, protein and shelling percent and due to saline water application there was increase in Na ion concentration in plant resulted in decreased K/Na ratio. Application of both humic acid and salicylic acid significantly increased the quality parameters and K/Na ratio in plant. The combined effect of saline water (4.0 dS m-1) with humic acid (1500 ppm) application showed that humic acid alleviate the detrimental effect of saline water by an increasement in such quality parameters and K/Na ratio. The combined effect of humic acid and salicylic acid (HA+SA) was also found significant and recorded maximum protein content (26 %) and K/Na ratio (6.01). Application of salicylic acid (1.5 mM) also significantly increased the K/Na ratio in salt stressed conditioned and maintain the ionic balance in cell sap.
