What is the system of rice intensification innovation?
INTRODUCTION. The System of Rice Intensification (SRI) is an innovation in rice production systems that is still evolving and ramifying, but already it is raising factor productivity and incomes for more than 1 million small farmers producing rice around the world on over 1 million hectares.
What are the principles of system of rice intensification?
SRI Principles Early, quick and healthy plant establishment. Reduced plant density. Improved soil conditions through enrichment with organic matter. Reduced and controlled water application.
How SRI is different from conventional method?
While SRI entails higher cost on fertilizer and fixed inputs conventional method incurs higher cost on human labour. Irrigation seed cost is slightly higher for SRI than conventional method. SRI method of paddy production has led to an increase in the income of farmers through the adoption of new modern techniques.
What is Sri technology?
Top. System of Rice Intensification. System of Rice Intensification (SRI) is a methodology for increasing the productivity of irrigated rice by changing the management of plants, soil, water and nutrients particularly by eliciting greater root growth.
What is SRI method of rice cultivation?
The System of Rice Intensification involves cultivating rice with as much organic manure as possible, starting with young seedlings planted singly at wider spacing in a square pattern; and with intermittent irrigation that keeps the soil moist but not inundated, and frequent inter cultivation with weeder that actively …
What is Sri in rice production?
The System of Rice Intensification (SRI) is a farming methodology aimed at increasing the yield of rice produced in farming. It is a low-water, labor-intensive method that uses younger seedlings singly spaced and typically hand weeded with special tools.
What is SRI and what are its characteristics?
Why the SRI technique is important for the long term health of the rice farm?
Environmental Benefits of SRI There is good evidence that SRI reduces the water footprint of rice production by consuming 30 to 50 percent less irrigation water, and 20 to 25 percent less total water for irrigated production, which includes rainfall. To use a current slogan, SRI helps farmers get more crop per drop.
Why is the SRI technique important?
The System of Rice Intensification, known as SRI, can reduce water requirements, increase land productivity, and promote less reliance on artificial fertilizers, pesticides, herbicides, and other agrochemicals, all while buffering against the effects of climate change and reducing greenhouse gases (GHG).
What is SRI in rice production?
What method of rice cultivation is popular in South India?
Answer: The drilling method is popular in South India for rice cultivation.
What are the benefits of SRI?
SRI helps improve food security and requires less water and fewer seeds. It favours organic fertilisation, results in plants that are stronger, more resilient to extreme weather and more resistant to pests and disease. As a knowledge-based system, it also costs nothing to adopt.
