Comparing between the performance of mobile drip irrigation and surface irrigation on some soil Physical properties and yield of wheat Triticum aestivum L.


Field experiment was conducted in a silty loam soil at Al-anbar University, College of Agriculture, in Ramadi during fall season 2013-2014 to study the Compared to the performance of mobile drip irrigation and continuous surface irrigation in some physical properties of the soil (moisture distribution curves and hydro saturated conductivity and infiltration average). The study included two main factors: mobile drip irrigation and Continuous surface irrigation. The lay out of the study was according to RCBD with three replicates. The moisture distribution was studied for the treatments during three stages from plant growth stages between 0 - 0.40 m in horizon and vertical directions from the drippers and depth 0 - 0.40 m in Beginning, middle and end of the board bar Continuous surface irrigation .The moisture curves were blotted by surfer software; some of the physical properties for the treatments, As well as some of growth and productivity of the crop wheat. The moisture content was increased at source of dripping and decreased away from the dripper horizontally and vertically after ending irrigation process, The treatment of drip irrigation reduced the vertical & horizontal distribution of water in soil as compared with the surface irrigation. mobile drip irrigation caused density values rate reduction as it reached to 1.38 in comparison with 1.44 Mgm.m-3 for continuous surface irrigation, and increase soil porosity to 0.45 in comparison with 0.4treatmentsrespectivel. The irrigation system had a vital role in hydro saturated conductivity, however the mobile drip irrigation had led to significant increase in this average, the highest average was 9.18 at the mobile drip irrigation comparing to 8.15 for Continuous surface irrigation The mobile drip irrigation had a role in average increase of infiltration which gave 9.4 and 8.6 for continuous surface irrigation treatments. It was significantly increased productivity in the treatment of mobile drip irrigation if reached 5.360 ton. ha-¹ compared with 4.230 ton. ha-¹ in continuous surface irrigation.
