The Present investigation was carried out at S. V. Agricultural College & RARS, Tirupati to know the effect of amino acids in alleviation of terminal moisture stress in groundnut (Arachis hypogia).The results revealed a considerable significant varia-tion in all morphological, physiological and yield parameters. Among the different treatments glutamine 200 ppm followed by arginine 200 ppm recorded significantly highest pod yields (kg ha-1). A significant positive correlation was observed between SCMR and total chlorophyll content. Foliar spray of amino acids caused increased chlorophyll content; high SCMR values and moderate SLA resulted in better crop yield under moisture stress. The role of amino acids in remobilization of resources needs further investigation.
