Traditional methods of irrigation

Traditional methods of irrigation.
Rahat uses animal labour. Above the well, we tie a large wheel. An ox or cow would turn the wheel to draw the water from the well.
Also called the pulley system, it involves pulling up water from a well or other such source to irrigate the land. This is a time consuming and labour intensive process, but it is very cost-efficient. Also, using a moat avoids wastage of water.

Dhekli is a traditional system of irrigation.
It is done manually. A person has to take out water through a bucket and pour it into the field.
A chain pump consists of two large wheels connected by a chain. There are buckets attached to the chain. Further, one part of the chain dips into the water source. As the wheel turns, the bucket picks up water. The chain later lifts them to the upper wheel where the water gets deposited into a source. The empty bucket gets carried back down.

2. All living beings need water to live. Water is important for proper growth and development of flowers, fruits and seeds of plants. Water is absorbed by the plant roots. Nutrients dissolved in water get transported to each part of the plant. To maintain the moisture of the soil for healthy crop growth, fields have to be watered regularly.

4. Irrigation The supply of water to crops at different intervals is called irrigation. The time and frequency of irrigation varies from crop to crop, soil to soil and season to season. Importance- Water is vital for the growth of plants. And, there can be no plants or crops if they do not have access to water in some form. It is, thus, crucial to supply water to crops and plants in time as per their need.

6. Traditional methods of irrigation These irrigation systems were used in earlier years. However, even today some small farms in rural areas adopt these. Although they are cheaper than modern methods, they are not as efficient. Because they need human or animal labour to function 1. Rahat Rahat uses animal labour. Above the well, we tie a large wheel. An ox or cow would turn the wheel to draw the water from the well.

7. 2. Moat Also called the pulley system, it involves pulling up water from a well or other such source to irrigate the land. This is a time consuming and labour intensive process, but it is very cost-efficient. Also, using a moat avoids wastage of water.

8. Differentiate between Rahat and moat Rahat Moat A moat or pully system of irrigation is one that involves pulling water up from well or other water sources in order to water plants and other crops. It is not often in use as it can be time consuming and is not very efficient. Rahat uses animal labour. Liver system is a traditional method of irrigation in which animals like ox or cow are used to pull out water from the well. This water is then evenly spread out over the fields. It is cheap but not very efficient method of irrigation.

10. Traditional methods of irrigation 3. Dhekli It is a process of drawing water from a well or such similar source. Here we tie a rope and bucket to a pole. At the other end, we tie a heavy stick or any other object as a counterbalance. And we use this pole to draw up water 4. Chain pump A chain pump consists of two large wheels connected by a chain. There are buckets attached to the chain. Further, one part of the chain dips into the water source. As the wheel turns, the bucket picks up water. The chain later lifts them to the upper wheel where the water gets deposited into a source. The empty bucket gets carried back down.

11. Traditional methods of irrigation Dhekli Dhekli is a traditional system of irrigation. It is done manually. A person has to take out water through a bucket and pour it into the field. This causes a lot of water wastage and now for water scarcity, people don’t use this method of irrigation. Chain pump These use round disks attached to a long loop of metal chain. Each metal disc runs through a pool of liquid and some water is collected in it. When the chain is pulled, the metal disc rises up to the top, and the water held inside pours out, hydrating the earth and flora.
