Abstract: The field experiments were conducted to quantify the influence of furrow and clay pitcher irrigation methods on crop water productivity (CWP) and fruit yield of cucumber and watermelon crops in Yazd region in Central Iran. The comparison of the CWP of cucumber and watermelon indicates that in clay pitcher irrigation the value of CWP is 4.91 and 4.79 times as big as the furrow irrigation, respectively. The cucumber fruit harvesting stage was 49 days from June 2nd to July 20th. Total fruit yield was 2.5 kg per plant for pitcher irrigation and 2.04 kg per plant for furrow irrigation. The watermelon fruit harvesting stage was 55 days from 16 June to 10 August. Total fruit yield was 8.61 kg per plant for pitcher irrigation and 7.86 kg per plant for furrow irrigation. The results indicate that traditional pitcher method can prevent huge amount of water losses, especially in arid and semi-arid regions of the world.
