Target audience: This presentation is intended for policy and decision makers, managers of development projects, and stakeholders involved in agriculture, water resource and irrigation management.
Content Covered: This section focuses on the benefits and limitations of SRI application. Compared to the commonly known flooded rice production, successful applications of SRI have shown that farmers can raise their paddy yields by 50 to 100% or more, while using fewer farm inputs, especially water. While failed field trials also exist, it is important to note that SRI is still a 'work in progress' and evolving, and should be adopted to local conditions and traditions.
After a brief review of the six key elements of SRI, the benefits of SRI are discussed - increase in paddy yields, better rice quality, reduction in irrigation water use, and reduction in production cost. Constraints to implementing and scaling up SRI are also reviewed - psychological and technical barriers as well as farm labor.
With climate change, increasing variability of rainfall, and the growing competition for water and land, SRI offers a new opportunity for increasing the production value per drop of water and for reducing agricultural water demand.

Hi A.Kirankumar Singh
This is not my video. It belongs to the World Bank Institute. My only wish with these uploads, was to make these awesome SRI videos available to a broader audience. I couldn't upload my original message here. Don't know why. I have tried to send it to your profile.
Good luck with your SRI work
Kind regards
Chris
I am impressed with your videos on SRI and therefore I would like to request to allow me to use your videos for the purpose of training the farmers in my locality. Kindly allow me to download it. I hope that you will be kind enough to allow me in the interest of the farming community.
1:21 Father De Laulanie, a catholic priest, said :" Rice is not an aquatic plant". This is a revolutionary discovering.
The same question comes from me. Please allow me to download and distribute this video on my website, so many people can benefit from this.

lol watch the and reply the video nearly 20 time this is good source for my feasibility study thank for uploading it .
Very well explained and thoroughly researched. Good work.
Quite useful. Thank u
Sounds like a more labour intensive (and thus greater yeilding) method than the natural 'do nothing' method invented by Masanobu Fukuoka. SRI shares many of his principles except that he advocates broadcast seeding (in seed balls) into the standing stubble and trash of the previous crop.
Weeding is done by hand or hoe unless the rows are straight. The rotary weeder makes SRI better for easy organic production. The plants are also healthier in SRI, more leaves, heavier grains, deeper roots. the large spacing allows plants to fully express themselves and the numerous and larger leaves have maximized photosynthesis letting them put out more root exudates and increase soil organic matter and biology rather fast.
like to learn more about this application bec.we dont have much water now here in our land.thanks to the uploader.....
this is interesting to learn about, but why do they have to repeat the same things 5 to 10 times?
They mention it saves water like a dozen times at least. Is that really necessary?
Very useful thank you for uploading
I would like to ask your permission to use your video to show and teach farmers in our village. Thanks!
Planting in wider space ln square cm, how wider will the distance will be? 2cm, 3cm or 10cm? what is the measurement?
25cm by 25cm
Gostei muito do vídeo,mas não amostras com clareza demoro qui a pessoa venha aprender.
The spacing is so wide ..
How do you stop water not to flood wash away the rice paddy when the rain season?
😍😍😍😍😍😍😍😍😍😍😍😍😍😍
May i have the permission to upload videos of sri i need it for my farmers field school
Producsion/ha ??
50t/ha
@@ruthrakannakailayavathiyam2351 not hoak?
Not hoak?
lol, 50t/ha is crazy. That can't be true. I've heard the best people doing SRI are getting 12-16t/ha. But they have been doing it for over 10 years. The soil gets better each year because SRI is good for the biology in the soil and increases the carbon and nutrients. 12-16t/ha is still amazing when you consider in the United States using all the fancy chemicals and fertilizers they only average 6.5t/ha on their mega farms. Mas holek you can easily expect to increase your yield by 50% the first year compared to traditional methods, from 4t/ha to 6t/ha. or if your land is producing poorly possibly a lot more. like going from 1.5t/ha to 4.5t/ha a 150% increase if you have good compost, manure, and water management. You will get better at the SRI management as the years go by just like how the soil will grow better rice using SRI over the years.
i can feel the tumors
