The nursery is prepared between first and
second week of June. For one bigha
basmati a nursery of 30 -35m2 (mud beds:3
strips of 8m x 1.25m) is needed. For the
System of Rice Intensification (SRI), only
0.75- 1m2 (200-300g seed) of nursery is
required. Best is to make bunds all around
the nursery.
After harvesting the Rabi crop the nursery
area should be solarised by spreading
transparent plastic sheets for 3 to 4 days to
reduce soil-borne diseases and weeds.
In each nursery strip 25-30kg (2-3 baskets)
properly decomposed organic manure and
25g zinc sulphate is best applied.
Extraordinary yield with SRI : Facts or fallacy by Doberman speaks all....though practiced in 1980s in China , Medagaskar ..many refute yield advantage with SRI over conventional system...

System rice intensification (SRI) is an agroecological methodology for increasing the productivity of irrigated rice by changing the management of plants, soil, water and nutrients. System rice intensification is based on the cropping principles of significantly reducing plant population, improving soil conditions and irrigation methods for root and plant development and improving plant establishment methods.

Dear Hem C. Joshi,
Please have a look at these useful PDF attachments on system rice intensification (SRI).
Good luck
