Field experiments were conducted in clay loam soil of Tamil Nadu Agricultural University, Coimbatore during rabi, 2009-10 and 2010-11 to identify the suitable crop establishment methods, weed and nutrient management practices in direct seeded rice. The field experiments were laid out in split plot design replicated thrice. Crop establishment methods and weed management practices (M1: Direct planting system (DPS), M2: DPS + EPOE of almix @ 4 g a.i. ha-1, M3: DPS without thinning and hand weeding in the intersect + EPOE of almix @ 4 g a.i ha-1, M4: drum seeding) were assigned to main plots and nutrient management practices (S1: Absolute control, S2: Recommended fertilizer dose of 150:50:50 kg NPK ha-1 + 12.5 t FYM ha-1, S3: S2 + Pseudomonas fluorescens (Seed treatment @ 10 g kg-1 and soil application @ 2.5 kg ha-1 and 0.2 per cent foliar spray), S4: S2 + Azophosmet (Seed treatment @ 2 g kg-1 and soil application @ 2 kg ha-1) + 0.1 per cent Pink pigmented facultative methylotroph (PPFM) foliar spray) were allocated to sub plots. The results showed that the highest growth, yield attributes, grain yield and harvest index were obtained by direct planting system (DPS) + EPOE of almix at 4 g a.i. ha-1. The drum seeding produced the highest straw yield. The combined application of recommended dose of fertilizer (150:50:50 kg NPK ha-1) along with 12.5 t ha-1 FYM and biofertilizers viz., Azophosmet as soil and seed treatment and 0.1 per cent pink pigmented facultative methylotroph (PPFM) as foliar spray at active tillering, panicle initiation and 50 per cent flowering stage registered higher growth, yield attributes, grain and straw yield and harvest index.

Keywords: Direct seeded rice, Growth attributes, Harvest index, Yield attributes, Yield.
