Reduction of Drought Stress Effects on Guar (Cyamopsis tetragonoloba L.) using Ascorbic Acid and Calcium Carbonate

Background: How plants respond to stress conditions can play an important role in the establishment and increasing crop yield. The results of researchers’ reports indicate that extensive morphophysiological biochemical changes occur under drought conditions. This study aimed investigate effects ascorbic acid (AA) calcium carbonate (CC) on guar different soil moisture Methods: experimental treatments included three levels (30%, 50% 70% field capacity, FC) foliar application (no application, with CC AA 0/003 concentration). Result: Drought caused increase sugar content relative other treatments. An intensity led proline content, soluble protein ascorbate peroxidase (APX) enzyme activity. On hand, Leaf water (RWC) decreased significantly. increased RWC control condition. In general, availability below FC seems induce countermeasures guar. Foliar effectively mitigate this plant.
