Plots naturally infested with Rotylenchulus reniformis were sampled in the spring of 2006 and 2007 at depths of 15 and 30 cm in the bed, furrow over the drip tape, and "dry" furrow, and at approximately 40 to 45 cm depth in the bed and dry furrow. Then, 1,3-dichloropropene (Telone EC) was injected into the subsurface drip irrigation at 46 kg a.i./ha, and 3 to 4 weeks later the plots were resamp...

In this research, the hydraulic behavior of furrow irrigation was investigated under cut-back, Walker-Skogerboe and conventional methods at the three experimental farms of Lavark, Shervedan, and Isfahan University of Technology for three irrigation events. In each farm, data were collected for each of the above methods with at least three replications including furrow shape, furrow length, furr...

In order to optimize the irrigation system performance, it is essential to get information about water balance components in the farm. So, the objective of this study was evaluating the performance of the WFD device in determining water penetrated fate in the soil at each irrigation occurrence as one of the important components in evaluating the irrigation water efficiency. By having the water ...
