Irrigation is the process by which water is supplied to crops at different intervals. The time and frequency of irrigation varies according to different seasons, crop, and soil types. There are various sources of irrigation such as wells, canals, rivers, dams, ponds and lakes.
Answer:
Irrigation is the process of applying water to the crops artificially to fulfil their water requirements. Nutrients may also be provided to the crops through irrigation. The various sources of water for irrigation are wells, ponds, lakes, canals, tube-wells, and even dams. Irrigation offers moisture required for growth and development, germination, and other related functions.
There are different types of irrigation practised for improving crop yield. These types of irrigation systems are practised based on the different types of soils, climates, crops and resources. The main types of irrigation followed by farmers include:
Surface Irrigation
In this system, no irrigation pump is involved. Here, water is distributed across the land by gravity.
Localized Irrigation
In this system, water is applied to each plant through a network of pipes under low pressure.
Sprinkler Irrigation
Water is distributed from a central location by overhead high-pressure sprinklers or from sprinklers from the moving platform.
Drip Irrigation
In this type, drops of water are delivered near the roots of the plants. This type of irrigation is rarely used as it requires more maintenance.
Centre Pivot Irrigation
In this, the water is distributed by a sprinkler system moving in a circular pattern.
Sub Irrigation
Water is distributed through a system of pumping stations gates, ditches and canals by raising the water table.
Manual Irrigation
This a labour intensive and time-consuming system of irrigation. Here, the water is distributed through watering cans by manual labour.
