Wild flooding is used mainly for pastures and fields of native hay on steep slopes where abundant water is available and crop values do not warrant more expensive preparations. Machines cannot be used m this method because during spray of insecticides or fertilizers, the earthen walls of basins are damaged. Usually, a family or the local community of Indian farmers are engaged in this farming method who use the output for their own consumption. Newcomers will have a lot of questions about what irrigation method is right for them, and even seasoned farmers and gardeners can make mistakes from time to time. So in this presentation, we are going to discuss about the differences in the modern farming methods in comparison with old methods. It is a costly process and widely used in U.S.A. In present times, when water crisis is developing very fast everywhere, we should adopt improved techniques of irrigation to encourage suitable water management. It is relatively inexpensive because it requires minimum of preparation. Primitive methods of lifting water from wells for irrigation are still in vogue in the villages. Modern equipment’s can also be used in it due to absence of depressions and boundaries. Effect of soil composition is also visible on it. This is a primitive farming method and farmers still practice it in some parts of the country. An important advantage of the furrow method is that only 0.2 to 0.5 as much surface area is wetted during irrigation as compared with flooding methods of irrigation. Technology were not improved and machines were not utilized much in the olden times. Primitive or Simple Subsistence Farming: Primitive farming is the oldest form of agriculture and still prevalent in some areas of the world. Due to seepage in drains, wastage of water is caused. The application of water and piping systems needs to be designed according to the type of crops, topography and weather conditions typical to the geographical area. The strips are separated by low levees, or borders. Rate of infiltration is higher in sandy soils where frequency of watering is more. Method of irrigation is easy and it causes lesser erosion. The main source of water is located at the highest place in the field. The string str is a primitive. Of these groundwater system is the largest. As per soil, the time of keeping sprinkler at one place and duration between two irrigations should be as under: 1. In recent years, high labor costs for surface irrigation have increased the attractiveness of sprinkler irrigation. 1950, Egypt. Thanks for reading this article ( Methods of irrigation ). This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. Maintenance is more beneficial in case of tube well as compared to well and an engine. Crop production is higher by 20 to 40 per cent in drip irrigation method, because plants can get air and water in required quantities, resulting in regular growth of crops. Animals may cause damage to branch pipelines and dripper pipelines. 2. A skin or bucket is hung on a rope from the long end, and a the advantages of new irrigation method are as follows: 1. optimum use of water thus reducing water losses to high extent. That method runs and returns a new string (shown by alert). There are five basic methods of irrigation (flooding, furrow irrigation, trickle, sprinkling, and sub irrigation). Drip irrigation method saves 30 to 70 per cent water and it is possible to irrigate three times more area with the same amount of water. Basins are constructed around one or more trees depending on the topography, and the flow is turned into the basin to stand until it infiltrates. In this method, the whole field is divided into basins according to the capacity of water. Which organelle is known as “power house” of the cell? Patanjali, in Yogasutra of about the 4th century CE, explains a technique of yoga by comparing it to "the way a farmer diverts a stream from an irrigation canal for irrigation". Sub irrigation has been employed in the Egin Bench project, Idaho; in Cache Valley, Utah; in San Luis Valley, Colorado; and in the delta of the Sacramento and San Joaquin Rivers in California. From primitive gathering, some people have taken a step ‘upward’ on the economic ladder by learning the art of domesticating plants and their economy has moved into primitive cultivation. In check flooding the check is filled with water at a fairly high rate and allowed to stand unit the water infiltrates. In this method, weeds do not spread because water reaches only near plants and does not spread in the whole field. 3. It requires lesser number of labourers hence, it can be developed even where there are less workers. The primitive implement is everywhere the dig ging stick, usually merely a strong stick, with one end pointed or flattened (a rudimentary spade) and often hardened in the fire. Sprinkler irription method is an easy and simple method of irrigation in present times. Not everyone who uses an irrigation system has all the facts and knowledge about irrigation. Trickle irrigation is that method of irrigation in which water (and nutrients) are continuously applied at the base of each plant through small plastic tubes; virtually eliminates all evaporation from soil, deep percolation, and runoff, and leads to very high efficiency in the use of water. Water is delivered to the field in ditches spaced 50 to 100 ft apart and is allowed to seep into the ground to maintain the water table at a height; such that water from the capillary fringe is available to the crops. Lesser labourers are required for irrigation work. It is not suitable for all types of crops. 5. These are now being gradually replaced by pumps and tube-wells. Water from streams is utilized as soon as it emerges from forest areas and channelled to a series of accommodated, terraced fields. Plants gets suitable quantity of water by this method. The frequency, rate, amount and time of irrigation are different for different crops and also vary according to the types of soil and seasons. It is a kind of an artificial rain and, therefore, gives very good results. Terms in this set (...) Irrigation. It is also advantageous in heavy soils where infiltration would be inadequate in the time required for the flow to cross the field. It is usually waste of water, and unless the land is naturally smooth, the resulting irrigation will be quite uneven. 3. 1. 4. More wastage of water is caused if strips are wider. Close-up showing method of raising water from canals by means of spiral tube Contributor Names American Colony (Jerusalem). Give the name of the main events of post fertilization. It is a costly process and widely used in U.S.A. Photo Department, photographer Created / … In sandy soil, sprinkler set is kept at one place for 3-4 hours and duration of 8-10 days is kept between the two irrigations. Farming varies from subsistence to commercial type. Furrow irrigation method is resorted to where crops are one grown in rows. Irrigation methods. In 2013-14, only about 36.7% of total agricultural land in India was reliably irrigated, and remaining 2/3rd cultivated land in India is dependent on monsoons. Pot irrigation method is more suitable for areas having scanty rainfall. Verso (JPEG Image, 54.62 KB) Download Original File Request hi-res copy. In a few areas soil conditions are favorable to sub irrigation. They include; Basin Irrigation: This type of surface irrigation waters crops of flat land called basins, enclosed with bunds.
