Effect of Pgrs and Nutrients on Growth, Nitrate Reductase Activity, Soluble Protein, Proline Content and Yield in Bhendi Hybrid Under Salinity

An experiment was conducted to study the effect of PGRs { gibberellic acid (10 ppm), brassinolide (0.5 ppm), salicylic acid (100 ppm), ascorbic acid (100 ppm), benzyl amino purine (5 ppm)} and nutrients { K2SO4 (0.5%) + FeSO4 (0.5%) + Borax (0.3%) mixture and 19:19:19 (1%) mixture} on growth, NR enz...

Description
Summary:An experiment was conducted to study the effect of PGRs { gibberellic acid (10 ppm), brassinolide (0.5 ppm), salicylic acid (100 ppm), ascorbic acid (100 ppm), benzyl amino purine (5 ppm)} and nutrients { K2SO4 (0.5%) + FeSO4 (0.5%) + Borax (0.3%) mixture and 19:19:19 (1%) mixture} on growth, NR enzyme activity, proline, soluble protein content and yield of bhendi hybrid (COBh H 1) under saline condition. The treatments were given at 25 and 45 DAS as foliar spray. The results showed that, nitrate reductase activity, soluble protein and plant growth were reduced under saline condition where as proline content was increased compared to absolute control. Foliar application of PGRs and nutrients enhanced the NR activity, proline, soluble protein and plant growth under saline condition. Among the PGRs and nutrients, foliar application of salicylic acid (100 ppm) and brassinolide (0.5 ppm) showed the better performance to mitigate the effect of salinity.
