Abstract :
When irrigating the field, the water moves along the strips and transfers most of the water to the ends of the strips, preventing uniform irrigation. In the present study, in order to solve the mentioned problem, a system was designed, constructed and evaluated for the performance of the system, which by filling the created furrows, solved the problem of non-uniform irrigation and improved the irrigation performance. The plate adjoining system has two concave plates with a diameter of 35 cm, which float following the main plates of the boundary and along the created ridge, and by transferring a part of the soil of the ridge body, it fills the furrows. To be Field performance evaluation experiments were performed in 1397 in the research farm of the Faculty of Agriculture, Islamic Azad University, Shushtar Branch. A completely randomized factorial design design was used using SPSS software. Experimental treatments include: device type (boundary with furrow filling mechanism and boundary without furrow filling), plot distance (5 and 10 meters), on water loss rate (in cubic meters), labor cost to fill furrow Marzband, the time of border demarcation operations by Marzband The results show that by using the device for filling the furrows of the border and at a distance of 10 meters, the least amount of water wasted in the amount of 3985 cubic meters, the lowest labor cost to fill the furrow. Border guards are 100 thousand Tomans and the minimum time for border demarcation operations in agricultural fields is 120 minutes per hectare.
