Two field experiments were carried out during winter season of 2005-2006 and 2006-2007, in EL- Kassasien Horticulture Research Station, Ismailia Governorate. It aimed to study the effect of three irrigation water quantities (800, 1000 and 1200 m³/fed.) combined with three sowing dates (20^th Sep.,10^th Oct. and 1^st Nov.) on two cultivars (Victory freezer and Lincoln) of pea (Pisum sativum L.) grown under sandy soil condition using drip irrigation system. The result indicated that increasing water quantity up to 1200 m³/fed. led to a significant increase of plant growth (plant height, number of branches , leaves per plant and dry weight ) and yield and its components (number of seeds per pod, weight of 100 seeds, net ratio and Green pod yield per fed.).Sowing pea plants on 10^th Oct gave the highest value of plant height, number of branches and leaves per plant, dry weight of branches and leaves per plant and yield and its components. Victory freezer cultivar recorded the highest value of plant height, number of branches and leaves per plant, dry weight of branches and leaves per plant and yield and it components. Sowing Victory freezer cultivar on10^th Oct. with application of 1200 m³/fed.was the best interaction treatment for increasing plant height, number of branches and leaves per plant, dry weight of branches and leaves per plant and yield and its components.
