Abstract
A field experiment was conducted to study effect of using three irrigation methods: drip irrigation, sprinkler irrigation and surface irrigation (furrow irrigation) potato root in soil profile of disruption a gypsiterous soil during growth stage of potato crop at the Experimental Research station of Soil science and Water Resources Department, College of Agriculture Tikrit University. The experiment was carried out with a complete block design and four replicates. Potato crop (Solanum tuberosum L.) Dazry variety were sown on. for spring season2014. Root weight density were measured during the growth stage in soil profile. the result showed that: Root weight density (RWD) in the drip irrigation (DI) was the biggest during different growth stages of the plant These values were 1.77 mg cm-3 followed by sprinkler irrigation (SI) and furrow irrigation (FI) 1.39 and 1.3 mg cm-3 for the treatments. RWD values were the highest in sprinkler irrigation (SI) for 0-5 cm depth. The values were 0.66 mg cm-3 these values were the biggest for depth of 5-10 cm depth in drip irrigation (DI) The values were 0.92 mg cm-3 and for 10-15 and 15-20 cm depth in FI The values were 0.51 and 0.63 mg cm-3 respectively.
