  1. ADVANTAGES OF DRIP IRRIGATION • INCREASED YIELD • EARLY MATURITY • WATER SAVING • FERTILIZER SAVING • INCREASED FERTILIZER USE EFFICIENCY BY CROP • ENERGY SAVING • LABOUR SAVING • MARGINAL LAND & UNDULATED LAND CAN BE IRRIGATED • USE OF SALINE WATER IS POSSIBLE FOR IRRIGATION • REDUCED WEED GROWTH • LESS PROBLEM OF DISEASE AND PEST • MAKES INTERCULTURE OPERATIONS EASY

  6. DRIP IRRIGATION • In Drip Irrigation, the plant foliage remains dry . This prevents the diseases and leaf burns that are some times evident in sprinkler Irrigation. • In Drip Irrigation, the area between wetted strips is kept dry. This facilitates the movement of machinery and farm implements when irrigation is in progress. • Drip Irrigation is well suited to all soils and also for heavy soils with low infiltration rate or soils that from surface crusts when sprinkled. • Drip Irrigation requires no special land preparation.

  7. DRIP IRRIGATION • Drip Irrigation can not be used for frost protection or for cooling during period of hot weather like sprinkler irrigation. • Like sprinkler irrigation, Drip Irrigation can not be used or suitable for supplemental irrigation of large areas. • In dry , windy regions, Drip Irrigation of young tree plants in “light” soils encourages soil erosion due to the very limited wetted area. Strong winds also presents problems of anchorage.
