1. Introduction:

AWD Method. As more and more people are using water in homes, factories and agriculture, water is becoming increasingly valuable all over the world. Paddy uses a lot of agricultural water. Rice is the staple food of almost half the world’s population. By 2025, 15 to 20 million hectares of paddy fields may face water shortage. Scientists have discovered a method to tackle this problem. This is called watering at wet condition method. This method can save water by reducing water consumption. The field is kept dry for a few days before re-irrigation and the interval from one irrigation to another is longer than the traditional method of irrigation (in which water is applied in the standing water field). This reduces the number of irrigations during the life span of the crop, uses less shallow water and uses 25 to 30% less water and has no adverse effect on crop yield and quality.

2. How to make a water level watching pipe in the field?

AWD Method. The pipe can be made of plastic, bamboo or any other local material. Which helps the farmers to see the water level under the soil. Cut this material 4 cm long and 15 cm wide so that the water level can be seen easily. Holes are drilled on each side in the 20 cm section at the bottom of the pipe. The width of the hole should be 0.5 cm and the distance between the holes should be 2 cm. The inner diameter of the pipe is 15 cm so that when you open it, you can put your hand inside it and remove the dirt.

3. How to install a pipe inside a field?

The pipe should be placed inside the field at a distance of one meter from the enclosure so that it can be easily inspected. Apply the pipe to the length of the field in such a way that the part with 20 cm holes is in the ground and the other 20 cm part of the pipe without holes outside the ground. Also make sure that it does not sink into hard ground through which water cannot pass. Remove dirt from inside the pipe and make sure the water level inside and outside the pipe is smooth. AWD method is a great way to help farmers reduce water use quickly and successfully. All farmers can really benefit only if it is done on a large scale.

4. How to apply watr (وتر) water?

The method of applying watr water is to observe the water level inside the field. After watering the field, the water level starts to decrease. When the water goes 10 to 15 cm below the ground level, the field is given 5 cm of water. This method of letting the field go down 10 to 15 cm before re-irrigating is called safe watr watering method. Due to the range of 10 to 15 cm there is no reduction in production. Because the roots of the paddy plant can take water from a wet place. The water pipe inside the field helps the farmers to see the hidden reservoirs of water. If there are more herbs in the early days of the crop, the watering method of watr is postponed for two to three weeks so that the weeds can be removed by keeping the water standing.

Regional recommendations on fertilizers in paddy can also be used. Apply nitrogen shortly before watering dry land. The water level in the field is kept up to 5 cm one week before and one week after the condition of the dough stage. so that there is no shortage of water. Use safe watr water after dough stage and during grain formation. The water saving method of watr water method is 25 to 30%. And production does not decrease. When farmers are convinced that there is no shortage of production in water of safe watr, they can reduce this level and experiment at 20 cm or more.
