ADVANTAGES AND RICE ORGANIC FARMING METHODS SRI ( System of Rice Intensification )
Innovation SRI method
SRI rice cultivation technique which is able to increase the productivity of rice in a way
changing the management of plants , soil , water and nutrients , have proven successful in increasing the productivity of rice by 50 % , even in some places reaching more than 100 % .
This method was first discovered by coincidence in Madagascar between 1983 -84 by Fr . Henri de Laulanie , SJ , a Jesuit priest from France more than 30 years living with the farmers there . By the inventor , the next metododologi in French called Ie systme de Riziculture Intensive abbreviated SRI . In English, popularly known as the System of Rice Intensification SRI abbreviated .
Association was formed in 1990 Tefy Saina ( ATS ) , a Malagasy NGO to introduce SRI . Four years later , Cornell International Institution for Food , Agriculture and Development ( CIIFAD ) , began cooperating with Saina to introduce SRI Tefy around Ranomafana National Park in Madagascar East , supported by the U.S. Agency for International Development . SRI has been tested in China , India , Indonesia , the Philippines , Sri Lanka , and Bangladesh with positive results . SRI became world famous through the efforts of Norman Uphoff ( Director CIIFAD ) . In 1987 , Uphoff hold a percentage of SRI in Indonesia, which was the first held outside of Madagascar SRI SRI method is very satisfactory results . In Madagascar , in some infertile land that normally the production of 2 tons / ha , farmers using SRI obtain yields of more than 8 tonnes / ha , some farmers have gained 10-15 tonnes / ha , and some have reached 20 tons / ha . SRI method yields at least two times higher than the usual method used by farmers . It just takes an open mind to accept new methods and willingness to experiment . In SRI plants are treated as a living organism as it should be , instead of being treated like machines that can be manipulated . All elements of the potential in rice plant developed by providing suitable conditions to grow .
The principles of organic SRI method of rice cultivation
1 . Young seedlings aged less than 12 days after sowing ( HSS ) when seeds are still
leaved 2 strands
2 . Seedlings planted one tree perlubang with a distance of 30 x 30 , 35 x 35 , or more rarely
3 . Transplanting should be as soon as possible ( less than 30 minutes ) and had to be careful so that the roots
do not break up and planted shallow
4 . Provision of water up to 2 cm ( Macak - Macak ) and dried until a certain period of rupture ( Irrigation intermittent / interrupted )
5 . Weeding since its inception about 10 days and repeated 2-3 times at intervals of 10 days
6 . Wherever possible use of organic fertilizer ( compost or green manure )
The advantages of SRI
Water -efficient plants , During growth from planting to harvesting of giving airmax 2 cm , the most well - Macak Macak about 5 mm and no drying period until the soil cracks ( Irrigation disconnected )
Cost-effective , it only took 5 kg seeds / ha . Revocation seed does not cost , it does not require the cost of moving seedlings , planting less power etc. .
3 . Save time , young seedlings planted 5-12 HSS , and the harvest will be early
4 . Production increased , in some places reached 11 tons / ha
5 . Environmentally friendly , uses no chemicals and replaced with the use of organic fertilizers ( compost , cages and Micro - Local oragisme ) , as well as the use of pesticides .
Organic Rice Cultivation Techniques of SRI
1 . preparation of seed
Seed before sowing tested in a salt water solution . Enough salt water solution to
test solution when the seed is put the egg , then the egg will float .
Good seed to be used as seed is the seed that is immersed in the solution .
Then the seeds were tested soaked in plain water for 24 hours and then drained
and brooded 2 days , then planted in soil medium and organic fertilizers ( 1:1 ) in
in a rectangular container measuring 20 x 20 cm ( pipiti ) . During the 7 days . After 7-10 days of age
rice seeds are ready planted
2 . Tilth
For land treatment SRI method of rice planting was not different from the way of processing
land for rice planting is done in conventional ways to obtain the structure of the soil
better for plants , is spared the weeds . Processing is done two weeks
before planting using hand tractors , until it forms a mud structure .
Leveled ground surface to facilitate control and water control .
3 . fertilization treatment
Fertilizer at SRI directed to the improvement of soil health and replenishment
nutrients decreased after harvesting . Organic fertilizer needs first
after using the conventional system is 10 tonnes per hectare and can be given
until 2 seasons garden . Having looked soil organic fertilizer can improve the
reduced as needed. Organic fertilizer is done in stages
The second tillage that can blend with soil fertilizer .
4 . maintenance
SRI method of cultivation system does not require continuous puddle , quite
with wet soil conditions . Flooding is done only to simplify
maintenance . In practice, the management of water in the system can be made of organic rice
as follows : in the age of 1-10 HST flooded rice plants with an average height of water
1cm , then at the age of 10 days weeded . After weeding
plants are not flooded . For treatment still needs weeding
next , then two days before the weeding plants digenang . At the time of the plant
flowering , plant digenang and after the milk cooked rice crop is not flooded back
until harvest .
To prevent pests and diseases at SRI chemicals are not used , but
pencengahan done and in case of pest / disease used pesticides
or used vegetable and physical and mechanical control
Yields on the SRI method in the first season was not much different from the previous results
( conventional method ) and continued to rise in the next season in line with the increase in organic matter and soil health . Produced from organic rice cropping system in the first season have the same price with conventional rice cropping system , the price is based on the assumption that the rice is not classified as organic , because the land is still there chemical fertilizer is left of the previous growing season . And for the next season by using SRI methods respectively , then until season 3 to be obtained organic rice and will be thinking about the higher price of rice paddy from the conventional system .
SRI System Benefits
In general, the benefits of SRI cultivation method is as follows
1 . Save water ( not digenang ) , Water needs only 20-30 % of the water requirements for how
conventional
2 . restoring soil health and fertility , and to realize the ecological balance of the land
3 . Forming independent farmers are able to research and become experts in their own land . Not depend on chemical fertilizers and pesticides manufactured increasingly expensive and sometimes scarce
4 . create jobs in rural areas , reduce unemployment and increase
family income of farmers
5 . resulted in the production of high- yield rice healthy , and does not contain residues
chemical
6 . pass on healthy soil for future generations
CONCLUSION
SRI method beneficial for farmers , due to increased production to 10 tonnes / ha , because otherwise it does not use chemical fertilizers and pesticides , the soil becomes loose , increased soil microorganisms so environmentally friendly .
To accelerate the deployment of SRI methods need support with central and local government policy
