The area is divided into strips with bunds either side to check lateral movement ofwater (Fig.1).Inthe strip water moves in an elongating thin sheet. 17.1. Methods of irrigation surface irrigation Surface irrigation Uncontrolled flooding, Border strip,Check,Basin,Furrow method. The width of the strip varies from 10 to 15 meters and length varies from 90 m to 400 m. Strips are separated by low embankments or levees. The water spreads and flows down the strip in a sheet confined by the border ridges. It may vary from 1m2 for growing vegetables and other intensive irrigation to 1- 2 hectares for growing rice under wet land conditions. 5 ing a slight change in the borders, so that the latitude as regards rotation is rather wide. Borders can be up to 800 m or more in length and 3-30 m wide depending on a variety of factors. We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads.

This method is especially suited to forage crops,its advantage being that for a relatively low investment a system can be developed which can afford the highest irrigation efficiency and lowest labour requirements. 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. In a levelled ground, the plots are generally rectangular, but if the ground has same initial slope, the checks or levees may follow contours. Border strip irrigation (or simply ‘border irrigation’) is a controlled surface flooding. Figure 4 illustrates a typical border configuration in which a field is divided into sloping borders. (2) Border flooding or Border Strip Method In this method, the land is divided into a number of strips, separated by low levees called borders. It minimizes the loss of water by deep percolation below the root zone or by evaporation from the soil surface. In this method, the farm is divided into a number of. Required fields are marked *. However, the more common size varies from 0.03 to 0.06 hectares for medium soils. 33.2.4 Border Strip Length. This method is suitable for row crops.

This depends upon, The following lengths are suggested for moderate condition, The first 6 to 12m length of the strip should be made level to ensure uniform spreading of water. To irrigate, water is turned from the supply ditch onto the head of the border. Overhead or Sprinkler Irrigation: In this method an attempt is made to simulate natural rainfall. These strips are separated by low levees (or borders). The border strip has a uniform gentle slope in the direction of irrigation. This results in uneven distribution of water within the plot. 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. Border strip method is otherwise called border strip flooding method.

Border Irrigation: Also known as border strip, border irrigation waters land structured as long strips with bunds in separating these sloping strips. In this method, irrigation water from the field channel is fed to the border strip by simply creating the field outlet or using siphons or gates. The border is separated with small parallel low ridges on the sides. The main points regarding this are. Border Irrigation: In this method, a thin sheet of water advances down the narrow strip between line ridges and water infilters into the soil as the sheet advances, Fig. She believes a cup of coffee and a good book is the horizon of an ecstatic life. 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. Strip size: 10 to 20 m wide, and 100 to 400 m long. FLOOD IRRIGATION includes several methods: Border strip, basin, contour or bench border irrigation, flooding from contour ditches, wild flooding, and border ditch. The surface is essentially level between two borders so that the advancing sheet of water covers the entire width of the strip. (b) BORDER STRIP: This is a controlled method of irrigation. 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.
