Field experiments were conducted during Navarai Season at Experimental farm, Annamalai University to study the system of Rice intensification (SRI) and their effect on yield components and economics of rice crop. The treatment has the influence of combined effect of age of the seedlings, spacing, weed management by conoweeder, chemical weeding, manual weeding, nutrient management with organic and inorganic fertilizer and alternate wetting and drying on the growth character, (plant height, tillers hill-1, tiller m-2, leaf area index, dry matter production) of SRI were studied. Among the treatments, SRI (use of 8-12 days old seedling, 25  25 cm of spacing, saturation of water, four times conoweeding only inorganic) significantly increased the growth characters. This was followed by SRI (use of 8-12 days old seedlings, 25  25 cm of spacing, four times conoweeding, saturation water, use of 75% inorganic + 25% organic).
