alternate irrigation for agriculture cultivation

1. Alternate Wet & Drying Irrigation Metode Pengairan Basah Kering pada Padi Sawah

2. AWD Practically measurable method of managing intermittent paddy irrigation. Wet-dry irrigation by adjusting water in stagnant or dry conditions alternately AWD is carried out from planting until one week before the plants flower. Paddy fields are only irrigated when the depth of the groundwater table reaches + 15 cm, measured from the ground surface. This can be known with the help of a simple tool from a hollow pipe that is immersed in the ground. Based on the Balingtan trials in Banyumas, Purbalingga, and Banjarnegara (2016), the AWD method has the potential to increase grain yields by 1 ton/ha

3. Purpose of AWD Installation Efficient use of irrigation water Nitrogen nutrient uptake efficiency Reduce OPT attacks Creates an oxygen-rich environment Increased rice production Reducing greenhouse gas emission

4. Making of AWD Pipe Prepare a 35 cm long pipe with a diameter of 10-15 cm Make small holes 20 cm high in the pipe The pipe that has been given a hole is planted in a paddy field and above the ground surface as high as 15 cm

5. AWD Application AWD was installed before/immediately after planting and immersed to a depth of 20 cm. AWD height 15 cm above ground level. After installation, remove the soil from the pipe Measurements start at 7-10 dap on each tapin and 21 dap on the tabela system The level of water level is monitored / monitored every two days and recorded. If the water level in the pipe is less than 15 cm, the paddy fields will be drained by water immediately. Rice does not need to be inundated with water all the time At the time of filling the grains of rice plants are flooded with water. At 7 -10 days before harvest the fields are dried.

6. Things to consider in water management with AWD At the time of flowering, maintain a water level of about 3-5 cm from the soil surface At the time of fertilizing the water in the paddy fields, the conditions were mixed Rice fields must be irrigated immediately if the water in the pipe has decreased to 15 cm below the ground level
