Drip Irrigation method is now a longtime approach to irrigation in water scarce components however it is usually gaining significance in water ample parts. during this expertise, the cropped box is irrigated within the shut region of root quarter of crop. It reduces water loss happening via evaporation, conveyance and distribution. for that reason excessive water use potency might be accomplished.

Common micro elements are iron, manganese, zinc, copper, molybdenum and boron. The functions of plant nutrients which support the plant system are briefly discussed below: Nitrogen (N): The nitrate form of nitrogen is not held in soils. Nitrates move with other soluble salts to the wetted front. This is of particular interest since NO3-N should always be applied with irrigation and at desired concentration needed by the crop to satisfy its nitrogen requirement from one irrigation event to the other.

The casing is built of metal or plastic material. It has four apertures: water inlet, outlet, draining valve and cover. It consists of a screen made of metal, plastic, or synthetic cloth enclosed in a special house used to limit COMPONENTS OF DRIP IRRIGATION SYSTEMS Fig. 6: Centrifugal filter (Phocaides, 2000) 47 48 AN INTRODUCTION TO DRIP IRRIGATION SYSTEM maximum particle size. 2). Most manufacturers recommend 100 to 200 mesh screens for drip irrigation system. Normally, the discharge through the screens is less than 135 lps per square meter of screen openings.

Distance between emitters and emitter flow rates must match to the wetting characteristics of the soil and the amount and timing of water to be supplied to meet the crop needs. Under drip irrigation, the ponding zone that develops around the emitter is strongly related to both the application rate and the soil properties. The water application rate is one of the factors which determine the soil moisture regime around the emitter and the related root distribution and plant water uptake patterns.
