Steps in SRI method of rice cultivation
In the year 1983, Father Henry De Lauleni developed a method to achieve more rice production from per unit area. This method is known as the Madagascar technique. And it is very popular as SRI method or the System of Rice Intensification.

(01). Importance of SRI method of rice
- First, High production of paddy with minimum use of land. Second, High production of paddy with minimum use of water.
- Proper development of roots, more number tillers, and better photosynthesis is due to the greater planting distance.
- Solid grains and higher production is also a result of the greater planting distance.
The average production in irrigated condition is 6 to 7 tonnes per hectare.
(02). Raising of plant nursery
- Preparation of soil: Plough the field for 2 to 3 times to make the soil more fine and crumby.
- Size of nursery beds: 1. The length of the nursery bed is 10 m. 2. The width of the nursery bed is 1 m. 3. The height of the nursery bed is 15 cm.
- Number of seedbeds: 4 seedbeds of 40 square centimetre are sufficient for one acre of field.
- Application of compost: 1. Apply 50 kg of FYM in per seedbed at the time of seedbed preparation. 2. Cover the seeds with fine soil and FYM after the sowing of seeds.
- Sowing of seed: Use 500 g of paddy seeds for per seedbed. Hence, amount of seed is 2 kg.

Select 10 to 12 days old plants for transplanting. It is ideal stage for transplanting.
10 to 12 days old seedlings 30 to 40 days old seedlings
Difference: 1. Tillers 2. Roots 3. Absorption of moisture and nutrients. 4. Production.
(04). Method of transplanting
- Uproot the plants.
- Immediately transplant the plants.
Step 02: Transplanting
- Sow only one plant at a defined point.
- Depth of transplanting is 2 cm.
Step 03: Planting distance
- Plant to plant distance is 25 cm.
- Row to row distance is 25 cm.
- Distance can be altered depending on the soil fertility and the type of soil.

(05). Water management
- Don’t keep the field in water logging condition for a long time.
- Moisture is necessary during the vegetative state.
- Moisture is necessary to keep the roots moist.
- This practice will develop cracks in the paddy field.
- Plant will receive more oxygen those these cracks.
- Plants experience a greater root development and expansion.
- Roots become more capable of distributing minerals and nutrients across the plant.
- Hence, plant receives more amount of soil nutrients.
- Fill the paddy field with 3 to 4 inches of water during flowering.
- Drain out the water 10 to 15 days prior to harvesting.
(06). Weed management
- Hand weeding: Do hand weeding at least 2 to 3 times during the vegetative state.
- Mechanical weeding: 1. Do first weeding after 15 days of transplanting. 2. Do second weeding after 25 days of transplanting. 3. Do third weeding after 35 days of transplanting.

(07). Manures and fertilizers
Manures: Use green manure. Grow green manure plants in the same field at least 1 month before rice cultivation.
FYM: 5 to 10 tonnes per hectare.
Fertilizers: Paddy requires carbon, oxygen, hydrogen, nitrogen, phosphorus, potash, sulfur, magnesium, zinc, iron, bronze element, molybdenum, boron, manganese, nickel, cobalt, and chlorine for its development.
Nitrogen, phosphorus, and potash are major nutrients. Soil testing is necessary before the application of fertilizers. The critical stage of plants should get the ample amount of fertilizers. Sowing, transplanting, and tillering are the critical stages.
(08). Important points
- Root should be straight.
- Flooding is not an ideal condition.
