Salinity causes adverse effects on morphological and physiological parameter of plants resulting\nin the reduction of crop growth and yield. Experiment was conducted in University of Sargodha\nsub campus Bhakkar from 18th June to 20th September 2016 by using two native mung bean\nvarieties vizAzri-2006 and NM-2011 by applying salicylic acid under different salinity\nlevelsi.e30 mM, 40mM and 50mM NaCl along with control treatment. Results indicated thatthe\ntreatment T3 of salicylic acid raised the number of pods and their size was recorded in AZRI\n2006 under 40mM salt stress. Salicylic acid application raised the number of seeds maximum\n(14.33) at T3 treatment in AZRI 2006 under 50 mM salt stress. Utmost plant height 69.99 cm was\nobserved at T3 treatment of salicylic acid in NM 2011 under 30 mM salt stress. T3 level of\nsalicylic acid increased the root fresh weight most of all in AZRI 2006 i.e. 7.24 grams. Highest\nproduction of total phenolic content 57.4 mg/gram was recorded at T3 level of salicylic acid in\nNM 2011 under 40 mM salt stress. Similarly more photosynthetic efficiency was estimated at T3\ntreatment in AZRI 2006 under 50 mM salt stress. Maximum reduction i.e. 695 mmole/gram in\nhydrogen peroxide species was observed in AZRI 2006 at T3 salicylic acid treatment under 50\nmM salt stress. Results indicate that foliar application of salicylic acid is better strategy for yield\nof mung bean under salinity condition as compared to high cost techniques such as plant\nbreeding.
