A field experiment was carried out to investigate the effect of System of Rice Intensification (SRI) practices on the growth, yield and nutrient uptake of short duration rice variety ADT 43 at the tail end of Cauvery delta zone during kharif, 2005. Twelve treatment combinations (YOSC, NOSC, YMSC, YOSH, NMSC, NOSH, YMSH, YORH, NMSH, YMRH, NORH and NMRH) were replicated thrice in a Randomised Block Design. The results revealed that when all the four components of SRI viz., young seedling (14 days old), one seedling hill -1 , square planting with wider spacing (22.5cm x 22.5cm) and conoweeding (YOSC) were practiced, it profoundly enhanced the growth and nutrient uptake which in turn improved the yield attributes and yield. The enhancement in the performance of rice was linearly proportional to the number of SRI components being practiced. As the SRI components increases, the performance of rice enhances.
