Introduction

• Micro irrigation is a modern method of irrigation by which water is irrigated through drippers, sprinklers, foggers and by other emitters on surface or subsurface of the land.
• Major components of a micro irrigation are Water source, pumping devices (motor and pump), ball valves, fertigation equipment, filters, control valves, PVC joining accessories (Main and sub main) and emitters.
• In this system water is applied drop by drop nearer the root zone area of the crop.
• The drippers are fixed based on the spacing of crop. Many different types of emitters are available in the market. They are classified as Inline drippers, online drippers, Micro tubes, Pressed compensated drippers.
• Drip irrigation is most suitable for wider spacing crops.
• Micro sprinkler irrigation system is mostly followed in sandy or loamy soils. In this method water is sprinkled in a lower height at various directions.
• Portable micro sprinklers are also available. They distribute slightly more water than drippers and micro sprinklers. They spray water in not more than one meter. It is used for preparing nursery and lawns in soils with low water holding capacity.
