Content

Irrigation may be defined as the process of supplying water to land by artificial means for the purpose of cultivation.

Ordinarily water is supplied to land by nature through rain but generally it is not enough for the proper growth of plants.

As such as the basic objective of irrigation is to supplement the natural supply of water to land so as to obtain they an optimum yield from the crop grown on the land.

Introduction

Drip irrigation, is also known as trickle irrigation or micro irrigation or localized irrigation, is an irrigation method that saves water and fertilizer by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters.

What is Drip Irrigation?

Pumping set Filters Mainlines Sub-main lines Laterals Emitters

Components of Drip Irrigation:

Pumping set:To create a pressure

about 2.5 Kg/sq cm to regulate the amount of water to be supplied.

• Filter :To filter the water in Order to remove the suspended impurities from water.

Main lines:It is a Distribution system in drip irrigation. Rigid PVC and high density polyethylene pipes are used as main pipes to minimized corrosion and clogging.Pipes of 65 mm diameter and with pressure rating of 4 to 10 kg/sq. cm

Sub Main lines:It is usually connected to the main lines through a control valve assembly.

EmittersThese connect to the tubing or can be inside the tubing and deliver water at a slow, consistent rate, usually, 0.5, 1, 2 gallons per hour.

Drip irrigation saves water because little is lost to runoff or evaporation.

This watering method also promotes healthy plant growth, controls weed growth, and reduces pest problems.

Why should I use drip irrigation:

Surface Irrigation Methods: The water is applied by spreading in it sheets or small streams on the land to be irrigated.

METHODS OF IRRIGATION

Sub-Surface Irrigation Methods: The water is applied below the ground surface so that it is supplied directly to the root zone of the plants.

Sprinkler Irrigation Methods: The irrigation water is applied to the land in the form of spray, somewhat as in ordinary rain.

Drip irrigation is useful for crop

Fruit crops :Banana, Grapes, Citrus, Pomegranate ,Papaya, Pineapple, Watermelon, Sweet lime, Mango.

Vegetable crops : Cabbage, Cauliflower, Okra, Tomato, Potato, Onion, Chillis, Radish, Brinjal, French been, Capsicum, Bhindi, Beans, Carrots, Cucumber, Bottle gourd, Gherkins. Commercial crops : Sugarcane, Cotton, Ground nut.

Reduced water use Reduced pest problems Simplicity Low pumping needs Automation Adaptation Production advantages Weed control High yield Joint management of irrigation

ADVANTAGES

Drip irrigation requires an economic Investment Drip irrigation requires maintenance and high-quality

water Water-application pattern must match planting pattern Shallow root depth. Safety Leak repair

DISADVANTAGES

Drip irrigation is a latest sub-surface method of irrigating water with higher water demands in arid region.

It may not be applicable to all farms. Drip irrigation increase yields.
