Irrigation systems reduce risks of low profitability from low yields and crop stress. Abstract. There are different ways of application of irrigation water to the farm land known as irrigation methods, which ultimately define the magnitude of field losses and thus the field application efficiency. 3- Possibility of vegetation growth in banks, leading to increased friction. Irrigation, the addition of water to lands via artificial means, is essential to profit-able crop production in arid climates. The irrigation water is introduced into level or graded furrows or basins, using siphons, gated pipe, or turnout structures, and is allowed to advance across the field. At the same time traditional or flood irrigation is the irrigation method usually used in the old land, specifically in the v alley and delta with co mmon clay soil. The main advantage of this method is that it is cheap. The soil also con- veys and distributes the water over the field. The major advantage of an earth channel is its low initial cost, these suffer from certain disadvantages, like the following:- 1- Maximum velocity limited to prevent erosion. Rizwan Rather. The following figures show the schematic description of surface irrigation methods. Efficient irrigation relies on both uniform application and accurate scheduling to meet the demands of the crop. The furrow is a narrow ditch between rows of plants. Surface irrigation methods . This method is the most inefficient method of irrigation as only about 20 to 25% of the water is actually used by plants or crops. Drip or trickle irrigation is one of the latest methods of irrigation. Irrigation Methods John T. Phelan and Wayne D. Criddle There are three general methods of applying irrigation water to the land. • irrigation methods • irrigation system design • land grading and levelling • canals and structures • drainage • salinity • irrigation management At this stage, all the papers will be marked provisional because experience with the preparation of irrigation training material for use at the village level is limited. Water is distributed through a system of pipes usually by pumping. Irrigation Water Management: Irrigation Methods FAO -FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS Drawings by Gravity irrigation method. In USA also, 66% is by surface irrigation. This method can vary in different regions. This method of irrigation is widely used for row crops, and small furrows, called corrugations, have been used for forage crops such as alfalfa. 90% of world’s total irrigated area is under this method. Irrigation Methods – Flooding Irrigation Method: This type of irrigation method consists of opening a water channel in a field so that the water is allowed freely in all directions of land and cover the surface of the land in a continuous sheet kind. It is suitable for water scarcity and salt affected soils. Irrigation is the watering of land by artificial methods. It is labour intensive. A flow is introduced at one edge of the field and covers the field gradually. In surface irrigation the soil is the reservoir from which the plants draw the water they need. In this method, the irrigation method is distributed to the agricultural land through the small channels, which flood the area up to the required depth. 1. The rate of coverage (advance) is dependent almost entirely on the differences between the discharge onto the field and the accumulating infiltration into the soil. While this is a lesser issue for surface irrigation compared to other irrigation methods (due to the comparatively high leaching fraction), lack of subsurface drainage may restrict the leaching of salts from the soil. International Commission on Irrigation and Drainage, New Delhi 1986. Application of larger quantities ofirrigation water in excess ofthe soilmoisture deficit ofthe field also adds to the wastage. The checkbook method of scheduling enables irrigation farm managers to monitor a field's daily soil water balance (in terms of inches of soil water deficit), which can be used to plan the next irrigation. of irrigation. Surface irrigation is where water is applied and distributed over the soil surface by gravity. Irrigation types.pdf.

The type of crop, cost of water and energy, availability of skilled labor, and long-term cost of system ownership should be part of the evaluation process when selecting the irrigation system. The four methods of irrigation: Surface Sprinkler Drip/trickle Subsurface. 1 SUMMARY Smallholder irrigation schemes, operated by farmers This paper restricts itself mainly to a description of technical, economical and organizational aspects of those irrigation schemes that are operated and maintained by the farmers themselves.
