Field experiments were carried out from 2003 to 2005 at Agricultural College and Research Institute, Killikulam, Tamil Nadu to optimize the establishment techniques of System of Rice Intensification. The treatment consisted of types of nursery and age of seedling in main plot, three different plant geometry in sub-plot and 2 number of seedlings/ hill in sub sub-plot and replicated thrice. The results indicated that during 2003-04, productive tillers/m2 and filled grains/panicle was significantly influenced by age of seedlings and nursery type. Though system of rice intensification nursery with 14-days-old seedlings had registered higher productive tillers/m2 (449) and filled grains/panicle (129). Closer spacing (20 cm x 20 cm) had higher number of productive tillers/m2 (491) but number of filled grains/panicle (116.7) are lower. Number of seedlings/hill failed to exert any significant influence on yield parameters viz., productive tillers/m2 and filled grains/panicle. However, increased growth and yield of rice was achieved with planting single seedling/hill at a spacing of 20 cm x 20 cm. 20 x 20 cm spacing recorded N P K uptake of 121.7, 41.3 and 143.2 kg/ha respectively. Significantly higher grain (8.0 t/ha) and straw yield (9.1 tonne/ha) was recorded with 20 cm x 20 cm spacing followed by 25 x 25 cm. Available N was significantly lower (206.8 kg/ha) in conventional nursery with 14-days-old seedlings.
