Drip Irrigation
By:- Devansh Goel
Drip irrigation involves dripping water onto the soil at very low rates from a system of small diameter plastic pipes fitted with outlets called emitters. Water is applied close to plants so that only part of the soil in which the roots grow is wetted
Drip Irrigation
Crops Suitable for Drip Irrigation
Drip irrigation is most suitable for row crops like Grapes, Banana, Pomegranate, Orange
Crops

Suitability
Drip irrigation is suitable for most soils. On clay soils water must be applied slowly to avoid surface water ponding and runoff. On sandy soils higher emitter discharge rates will be needed to ensure adequate lateral wetting of the soil.

Sprinkler Irrigation
By:- Ria Agarwal
Sprinkler irrigation is a type of overhead irrigation. It is a method of supplying irrigation water which is similar to natural rainfall.

Suitable Crops:
Suitable Crops
Sprinkler irrigation is suited for most row, field and tree crops and water can be sprayed over or under the crop canopy. Like wheat, sugarcane, groundnut, cotton.
Components:
- Pump unit
- Mainline and sometimes sub mainlines
- Laterals
- Sprinklers

Advantages and Disadvantages
Advantages and Disadvantages
There is a lot of research going into developing efficient irrigation method
Advantages
- Prevents Nutrient Loss
- Water Efficiency
- Fields with irregular shape can be accomotadet.
Drip Irrigation
- Suitable for all types of soil
- Conserves Space.
- Uniform Distribution of Water.
- Conserves Water
Fun Fact: We also use this irrigation in our school.
Sprinkler Irrigation
Disadvantages
Disadvantages
- High Installation Cost.
- Low lifetime of piping.
- May cause clogging in pipes
Drip Irrigation
- High Maintainence Cost
- Water will drift due to wind.
- Water must be clean and free from all kinds of debris.
- Also require a high level of maintainence.

What do we plan to do?
- Currently writing a scientific paper.
- We aim to provide this affordable farming method with less water usage to farmers in India.
Future Plans
Areas of these systems:
Irrigation is crucial to the global food supply so time and again the world
improvises on the irrigation methods to increase the production of crops.
Areas
Drip Irrigation
Drip irrigation method is used worldwide ranging from countries like Nepal, India,
China and Israel.
California is the king of drip irrigation in the United states
Drip Irrigation
Regions
The top ten sprinkler irrigated countries were USA, Russia, China, India, France, Brazil, Italy, Spain, Saudi Arabia and Ukraine. These countries together constituted 75% of total sprinkler-irrigated area.

Importance:
-It helps to increase productivity even in low rainfall.
- It increases the income of the farmers.
- possible to grow more than one crop in most of the areas of the country.
-frost protection
