Irrigation Methods

Published on by in Social

What new innovative technologies and management measures in irrigation should be adopted in rice cultivation.

Traditionally, paddy is grown using huge amount of water. Now in my country we have started getting water shortage resulting trouble in rice cultivation. I would be interested in knowing some advance irrigation technologies for rice cultivation.

Can anyone help me with some suggestions?

  1. Irrigation Methods

    Water is an important input in rice production, Asian countries faces severe problems with increasing demand for water and limited water resources. In conventional paddy production, one of the most important irrigated crops, a significant amount of irrigation water is lost due to percolation and evaporation. Therefore, it exist a vivid research in water saving rice technologies. I been researching for some technical papers highlighting  water-saving rice production technologies. I came across some new technologies called, Drip irrigation and fertigation technologies, details can be seen here. http://www.scribd.com/doc/88516713/2012-AIF-D2S6b-Drip-Irrigation-and-Fertigation-Technology-for-Rice-Cultivation-by-Dr-P-Soman You can also see another paper on Alternate Wetting and Drying Irrigation (AWD): a technology for water saving in rice production here http://www.knowledgebank-brri.org/AWD/AWD_technology.pdf Hope this works for you. You may like to comment on limitations on these technologies as you are having experience of the paddy cultivation

  2. Mr. Chevion thanks a lot for providing me the valuable information. It is highly appreciated. I had heard about Panipipes project in Bangaldesh, now will gather more information about it. As the conditions are very similar at my country and in Bangaladesh. Thanks again, Gema.

  3. Depending on the location and cultivation method one could have different alternatives to irrigating rice. A few exmaples: - a project by Syngenta called pani-pipes looks at alternating flooding thus reducing the amount of water and increasing yield actually. These are essentially pipes that help look at the soil moisture and trigger irrigation only below a certain level (vs. being flooded 100% of the time). similar means are avaialble today with soil moisture sensors which can help make better decisions. - Irrigation of rice with drip irrigation is technically possible yet usually financially cahllenging. It works yet requires different management practices and in most cases requires plenty of education to smallholders and is too expensive for implenetation on a braod scale. - Use of mechanical (pivot/lateral) irrigation has also been used in the united states and has had good success with 30% less water yet requires the right scale. - Certain varieties are more adapt and some chemistries (Crop Enhancement by Syngenta) can help the plants mitigate water and heat stresses. clearly there are many other questions related to the soil, pest and diseases, nutrition and climatic conditions to enable an optimal production system which are related to the water and all play a role in the success or failure and need to be considered when thinking of a solution. Hopefully this helps. Peleg
