The supply ditch. Before we begin, let’s look at the classification of surface irrigation. In all the surface methods, Surface irrigation Uncontrolled flooding, Border strip,Check,Basin,Furrow method. Assumptions. Longer border strip are desirable to reduce the labour and other operating costs, however the aspect of uniformity and application efficiency of the border strip should be kept in mind while determining the length of the border. These strips are separated by low levees or borders and run down the predominant or any other desired slope. Water is admitted to these plots at the higher end and the supply is cutoff as soon as the lower part of the plot has received the sufficient depth of water. Border/bay strip method When using bay or border strip method, the water moves along parallel thin ridges on the surface that are aligned in long strips and in the process of moving the water is absorbed into the soil. In the border strip flooding method, the farm is divided into a series of strips 10 to 20 metres wide and 100 to 300 metres long. It minimizes the loss of water by deep percolation below the root zone or by evaporation from the soil surface. ... Border strip method Background and Objective: Border strip method of irrigation is a widely used surface irrigation technique which is best adapted to crops like wheat, barley, fodder crops and legumes. FLOOD IRRIGATION includes several methods: Border strip, basin, contour or bench border irrigation, flooding from contour ditches, wild flooding, and border ditch. The diagram below shows border strip method. Methods of irrigation surface irrigation Surface irrigation Uncontrolled flooding, Border strip,Check,Basin,Furrow method. Looks like you’ve clipped this slide to already. […] flooding, basin flooding, flooding by contour laterals, zigzag method of flooding, border strip flooding and check flooding are the 6 types of controlled flooding which is a subcategory of surface […], […] ALSO READ: Check flooding and Border strip methods of irrigation […], Your email address will not be published. In this method, the farm is divided into a number of. The size of stream should be sufficient to cover the entire basin in a relatively small portion of time required.

Now customize the name of a clipboard to store your clips. This method is suitable for row crops. Contour checks are prepared by constructing ridges along contours at vertical intervals of 6 to 12 cm and connecting them with cross ridges at intervals. The diagram given below shows check flooding. The size of check basins is dependent on the infiltration rate. E. Border strip method of irrigation The field is divided into a number of long parallel (3-10 ni x 50-30() m) strips which is called border. Border strip irrigation (or simply ‘border irrigation’) is a controlled surface flooding. In the blog, we are going to learn everything about these two with figures. I will surely cover other main categories in another blog. BORDER STRIP IRRIGATION IRRIGATING BORDERS BORDERS ARE IRRIGATED BY DIVERTING A STREAM OF WATER FROM THE CHANNEL TO THE UPPER END OF THE BORDER. 33.2.4 Border Strip Length. Border strip method is otherwise called border strip flooding method. | In the border strip, location of the opening(s) should cause sheet flow along the slope guided by the bunds on either side. method of applying irrigation water. The strip The size of levee depends upon the depth of water to be applies as well as the stability of the soil when it is wet. The border is usually adopted where topography permits precise land levelling at a reasonable cost and where relatively large irrigation streams are available. Border strip, otherwise known as border check or bay irrigation could be considered as a hybrid of level basin and furrow irrigation. 5 ing a slight change in the borders, so that the latitude as regards rotation is rather wide. Lay out the border strip so the lower end is lower than the upper end by about the average amount of irrigation water to be applied in one irrigation. The border is separated with small parallel low ridges on the sides. In a levelled ground, the plots are generally rectangular, but if the ground has same initial slope, the checks or levees may follow contours. Preparation of land for border strip irrigation is more expensive than for ordinary flooding, but this may be offset by a decrease in water waste because of … This method of irrigation consists in turning the water onto natural slopes without much control or prior preparation.… The method is also known as irrigation by plots since the entire area is divided into several plots obtained by subdividing the entire area by levees. To irrigate, water is turned from the supply ditch onto the head of the border. The present study was aimed to design an irrigation border to maximize water application efficiency which is very important to meet the growing water needs. The method is one of the most recent developments in irrigation. 2.2.2 Border irrigation. Your email address will not be published. The water is discharged into the strips via border gates, aluminum syphons or plastic piping, In this method, water is let into the strips by concrete risers. … These strips are separated by low levees or borders and run down the predominant or any other desired slope.
