What is SRI farming?
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 irrigation system is good for the rice crop?
drip irrigation
Rice plants actually prefer drip irrigation But, like most other grains, its optimal environment is actually aerobic.

Which is the best method of growing rice?
Answer: Transplantation is the most commonly used method wherein seeds are first sown in nursery and the seedlings are transplanted to the main field once they show 3-4 leaves. Although this is the best yielding method, it requires heavy labor. Drilling method is exclusive to India.
What are the principles of System of Rice Intensification SRI?
carefully and quickly › protecting the seedlings’ roots and minimizing the transplanting shock. singly › one plant per hill instead of 3-4 together to avoid root competition. widely spaced › to encourage greater root and canopy growth. in a square grid pattern › 25×25 cm or wider in good quality soil.
What is the best method of irrigation for rice?
Sprinkler or drip irrigation are preferred above surface irrigation on steeper or unevenly sloping lands as they require little or no land levelling. An exception is rice grown on terraces on sloping lands. Climate: Strong wind can disturb the spraying of water from sprinklers.
What is the system of Rice Intensification ( SRI )?
The System of Rice Intensification, known as SRI — le Système de Riziculture Intensive in French and la Sistema Intensivo de Cultivo Arrocero (SICA) in Spanish — is an agro-ecological methodology for increasing the productivity of irrigated rice by changing the management of plants, soil, water and nutrients.
Why do we need training in Rice Intensification?
The training on SRI is therefore eminent to augment the staff’s capacity in this direction and to subsequently deliver their services to the target beneficiaries.
What’s the difference between Sri and conventional rice cultivation?
A comparison of SRI and conventional method of rice cultivation is as follows Needs 50% more man-days for transplanting and weeding. Mobilises labour to work for profit. It offers an alternative to the resource poor, who put in their family labour. Once the right skills are learnt and implemented, the labour costs will be lesser.
What are the benefits of Sri in rice?
Benefits of SRI. The benefits of SRI have been demonstrated in over 50 countries ( see map ). They include: 20%-100% or more increased yields, up to a 90% reduction in required seed, and up to 50% water savings. SRI principles and practices have been adapted for rainfed rice as well as for other crops (such as wheat, sugarcane and tef,…
