This study was conducted in Jillen research Station/ General commission for Scientific Agricultural Research/ Daraa/ Syria, during the years 2008 and 2009, to study the effect of deficit irrigation on some morphological and biochemical parameters and yield components of green peas (Pisum sativum.L) using tow methods of irrigation (drip and sprinkler).three treatments of water (100%, 85%.70%) of actual water consumption (ETc) were given in three replication. Actual water consumption ranged between (171-206) mm, and (153.8 _ 187) mm in tow seasons respectively when drip irrigation were used, while it was (179.2 -229.6) mm, and (186.3 - 224.8) mm respectively in sprinkler irrigation results also showed that the highest yield were (11.311 tonnes/ ha), obtained when 100% of the actual water consumption was given, it was superior and much better compared with 100% of the actual water consumption in sprinkler irrigation using which reached to (9.92 tonnes / ha) ,and no significant difference when it compared with (10.65 tonnes / ha) when plants given 85% of the actual water consumption. Regarding (the number of pods on the plant, plant height, number of basal branches) the highest value were obtaining when 100% of the actual water consumption were given , while the lowest values observed when 70% of the actual water consumption were given in both methods.
