Although sustainable agriculture is not limited to production systems that use few or no purchased inputs, systems that are less dependent on external inputs have better prospects for sustainability—as long as they can meet the needs of producers and consumers as well as do conventional systems depending heavily on fossil fuel and other capital-intensive inputs. The system of rice intensification (SRI) developed in Madagascar can raise irrigated rice yields to about double the present world… 
System of Rice Intensification : A Review
The system of Rice intensification acronym as (SRI) was developed in the last two decades is an effort to find sustainable agricultural practices that can lead to higher productivity, optimum use of
Opportunities for water saving with higher yield from the system of rice intensification
The system of rice intensification (SRI) developed in Madagascar, is showing that by changing the management of rice plants, soil, water and nutrients it can increase the yields of irrigated rice by
The System of Rice Intensification (SRI) as a System of Agricultural Innovation
The System of Rice Intensification (SRI). developed in Madagascar some 25 years ago. is gaining increasing credence and momentum as probably 500.000 farmers in more than 20 countries are now using

ABSTRACT A large body of evidence indicates that SRI can enhance rice grain yield with substantially less water input than in conventional indsutrialized rice farms. While SRI conserves a large
Introduction of the System of Rice Intensification in Kenya: experiences from Mwea Irrigation Scheme
There are various avenues for intensifying agricultural production, the most common being increased use of fertilizers, supplemental irrigation of crops, and adoption of high-yielding varieties.
Sustainable intensification in agricultural systems.
TLDR
This review analyses recent evidence of the impacts of SI in both developing and industrialized countries, and demonstrates that both yield and natural capital dividends can occur.
Rice Yield Increase by the System of Rice Intensification is Dependent on Supplementary Water Availability in Rainfed Lowland Fields of Southern Cambodia
Increasing rice yield in rainfed fields is one of the major agricultural challenges in Cambodia. As an answer to this challenge, we focused on the System of Rice Intensification (SRI), which has been
Improving land and water productivity in basin rice cultivation in Kenya through System of Rice Intensification (SRI)
Improving the yield of rice (Oryza sativa L) in existing irrigated areas rather than further expansion is more likely to be the main source of growth for the crop in Kenya, especially due to limited

Agroecological Implications of the System of Rice Intensification (SRI) in Madagascar
A system of plant, soil, water and nutrient management for irrigated rice developed in Madagascar has been yielding 5, 10, even 15 t ha−1 on farmers' fields where previous yields averaged around 2 t
Breaking the yield frontier of rice
Major increases in rice production have occurred during the last 25 years, due to large-scale adoption of high-yielding semidwarf rice varieties. However, the rate of increase of rice production has

Comparison of plant measurements for estimating nitrogen accumulation and grain yield by flooded rice
TLDR
These low correlations of grain yield with plant measurements during the vegetative stage confirm that environmental and other conditions prevailing during later growth stages profoundly influenced grain yield of rice.
