In: Minufiya journal of agricultural research 2009.v.34(4)Summary: A field experiment was carried out during the two successive winter seasons of 2004-2005 and 2005-2006 at the Experimental Farm of Minufiya University in Sadat city, Egypt. The soil was sandy in texture. The aim of this investigation was to study the effect of irrigation treatments and sprinkler height on growth, yield quality and WUE of peas (Pisum sativum L.) variety Lincoln. Results exhibited that increasing irrigation level up to 100% ETa increased vegetative growth (plant height, branches no., leaves area. flowers no. and pods no. / plant, fruit set % as well as dry matter of stems, leaves, pods, roots and total plant) ) and green pods and dry seeds yields / fed. Pod length exhibited its highest value when plants were subjected to water deficit (60% ETo) whereas: irrigation at either 80 or 60% ETo had equal effect and showed the lowest pod length values. WUE for green pods and dry seeds yields showed the highest values when pea plants were irrigated at 80% ETo. while 60% Eto exhibited the lowest values. Generally, installation of sprinklers at 75 cm height produced tallest pea plants and higher leaves area / plant and fruit set %. However, dry matter of stem, leaves, roots. pods and total plant exhibited their highest values when sprinklers were positioned at 50 cm height. Flowers no. /plant was not affected by sprinkler height. The highest values of green pods yield/ fed., dry seeds yield/ fed., and pod length as well as pod weight were attained at 50 and/ or 75 cm sprinkler height. Moreover, the highest values of water use efficiency (WUE) for both green pods and dry seeds yields were detected at 75 cm sprinkler height. It could be concluded under the conditions of the experiment or any other similar conditions that pea plants can be irrigated by 100% and /or 80% ETo with sprinkler height 75 cm for obtaining higher green pods yield/ fed. , dry seeds Yield/ fed and WUE .
