Abstract

A field experiment was conducted in AL – Anbar Governorate-AL- Ramadi –Sufia district during the spring season, in a silt loam soil, to study the effect of exudation irrigation and surface drip irrigation in some physical properties, growth and cucumber yield: Bulk density and porosity, water infiltration, leaf area, dry weight of vegetative part and root, root and stem length and stem diameter, cucumber yield class Beit Alpha. The experiment was conducted using a randomized complete block design with three replicates, statistically analysis using the Genstat program.The results showed improvement in the physical properties studied when exudation irrigation, with significant in the rate density and porosity at the depth 0 – 20 cm, which reached 1.24 Mg m-3, 50.38% compared to 1.38 Mg m-3, 46.87% when drip irrigation, while significant, while non-significant were found in rate of Bulk density and porosity at depth 20-40 cm, increase in basic infiltration rate when exudation irrigation percentage by 36% at reached 8.9 cm h-1 compared to 5.7 cm h-1 when drip irrigation. The results showed significant in rate of leaf area, as it was 173.93 dm2 plant-1 when drip irrigation, 207.77 dm2 plant-1 when exudation irrigation statistical analysis showed significant in dry weight of vegetative part and root which reached 104.4g at drip irrigation compared to 57.5, 8.5g for exudation irrigation. The rate of stem length, root, stem diameter and total yield were found to be statistically non-significant.
