Aim: To study the Influence of nutrient management on growth, lodging and yield of transplanted rice.

Study Design: The study comprised of eight treatments viz.,T₁- 100% NPK, T₂- 100% NP + 125% K, T₃- 75% N + 100% PK, T₄- 75% N + 100% P + 125% K, T₅- 100% NPK + K₂SiO₄ at 50 kg ha^­-1, T₆- 100% NPK + Ca₂SiO₄ at 50 kg ha^­-1, T₇- 100% NPK + Na₂SiO₃ at 50 kg ha^­-1 and T₈- absolute control in randomized block design.

Place and Duration of Study: This research trail was conducted during the late samba (September – February) of 2021-22 at Anbil Dharmalingam Agricultural College and Research Institute. TNAU, Trichy, Tamil Nadu, India.

Methodology: The study consisted of combination of 8 treatments in RBD which was replicated thrice. The rice variety of IW Ponni was used for this study. The observation have been recorded during the different phases of growth at regular intervals.

Results: The results revealed that the application of 100% NPK + K₂SiO₄ at 50 kg ha^­-1 has
recorded significantly taller plant height (131.7 cm), higher dry matter production (11360 kgha^­-1), grain (4535 kg ha^-1) and straw yield (7259 kg ha^-1) over absolute control. Minimum bending
moment and lodging score were reported with 100% NPK + K₂SiO₄ at 50 kg ha^­-1 and it was on
par with 100% NPK + Ca₂SiO₄ at 50 kg ha^­-1.
