10. LEARNING OBJECTIVES 1.Differentiate kinds of irrigation water 2.Perform methods of irrigation;and 3.Appreciate the importance of proper irrigation management in agriculture

11. THREE KINDS OF IRRIGATION WATER 1.SURFACE IRRIGATION In this case water is applied over the surface of the ground, either in furrows or by spreading it broadcast over the land being irrigated. Water is conducted from the source to the points of distribution either in open ditches or pipe lines. This kind of irrigation is usually used in the Philippines for irrigating their rice fields.

12. THREE KINDS OF IRRIGATION WATER 2.SUB-IRRIGATION In this kind of irrigation the water is delivered to a porous stratum of soil at proper depth. The moisture spreads to the plant roots through this stratum.

13. THREE KINDS OF IRRIGATION WATER 3.OVERHEAD OR SPRAY IRRIGATION In this case, water is put into the plants in the form of very fine drops or spray or mist. In small scale, this method is used like in nurseries where water is applied by means of sprinklers, water hose with nozzles.

14. METHODS OF IRRIGATION Irrigation by hand. This requires hand labor. This system is used only where a valuable crop can be grown in a small piece of land, as in school and home gardens.

15. METHODS OF IRRIGATION 2.Irrigation by windmill It is used for irrigating a fruit plantation or a truck garden. This system furnishes a very satisfactory means of pumping water in some localities in the Philippines. It works well in sections along the seashores.

16. METHODS OF IRRIGATION 3.Irrigation by machinery Water pumps are set in the source of water. Water is delivered to the field through water hose

17. METHODS OF IRRIGATION 4.Irrigation by gravity This is the cheapest and most common method of obtaining water for irrigation. Ditch canals are dug from the source of water like streams or rivers going to the field thus water is taken from the river at an outlet that can be opened and shut down.

18. METHODS OF IRRIGATION 5.Drip irrigation Water passes to small pipes that are directed to the garden or field of crops. The water can be controlled by closing the source of water
