AbstractA field experiment was conducted at first ones using this kind of earthen wares during the spring season of 2010 at Al-Sufia district –Ramadi on clay loam soil ,classified as typic torrifluvent to study the effect of exudation, surface drip and partial root zone drying irrigation systems on some soil physical properties, growth and yield of tomato crop, this study was conducted as factorial experiment(RCBD)design with three replicates, Genstat software was used for data statistical analysis. The results obtained can be summarized as follows:
1- Exudation irrigation caused reduction in bulk density values rate and increment of soil porosity by 1.32 in comparison with 1.35 and 1.41 Mgm.m-3 for surface drip irrigation and PRD respectively, increment in porosity to 0.50 in comparing with 0.49 and 0.46 respectively .
2- The results showed that the increment in mean weight diameter at exudation irrigation significantly, by 0.35 in comparison with 0.34 for all of surface drip irrigation treatment and PRD , but there were no significant differences between SDI and PRD.
3- The irrigation systems had significant effect on root length rate which attained 39.80, 32.25 and 33.75 cm for SDI ,PRD and exudation irrigation respectively.
4- The results showed that these three irrigation systems had an effect on values of the rate of early yield and the total yield which approached to 8.53, 9.47 and 8.40 t.ha-1 for the early yield and 24.27, 25.87 and 22.93 t.ha-1 for the total yield in SDI, PRD and exudation irrigation respectively.
