| Abstract | ||
| Field experiment was carried out during spring season 2011 at Baa,quba city , Split-Split plot Design as RCBD of three replicates was used in this experiment the effect of three Proline acid levels ( 0 , 150 , 200 mg Proline .l-1 ) Three Abscisic acid levels ( 0 , 15 , 20 mgABA.l-1. ) and three periods of irrigation after(25, 50, 75%) of available water to reduce the negative effect of the moisture tension on the Corn Plant . The results showed that therd level of Proline sprayed ( 200 mg Proline .l-1 ) decreased the negative effects of moisture tension on the Plant height, leaf area , grainyield , biological yield and efficient use of water as compared with the both of control and the second Proline (150 mg Proline .l-1 ) treatments .The therd ABA level( 20 mg ABA.l-1) decreased the negative effects of moisture tension on the grainyield and biological yield and efficient use of water , However , mean grain yield , biological yield and water use efficiency in plant increased in values (14.36 % , 8.40 % , 17.04% ) respectively as compared with the control treatment(0 ABA applications ) The increase in yield was related to the roles of the Proline and ABA by improvement of the plant ability for water and increase of plant water use efficiency . | ||
