Field experiments were conducted at Annamalai University Experimental Farm, Department of Agronomy, Annamalai University, Annamalai Nagar during Thaladi and Navarai seasons, to optimize the agronomic strategies for plant growth dynamics of wet spot seeded rice in the coastal agroecosystem of Northern Tamil Nadu. The treatments comprised of four agroforestry tree green leaf manure integrated with N management viz., T1: control (RDN), T2 - 50 per cent N via., Pongamia pinnata and 50 per cent N via., inorganic fertilizer, T3: 50 per cent N via., Albizia lebbeck and 50 per cent N via., inorganic fertilizer and T4: 50 per cent N via., Azadirachta indica and 50 per cent N via., inorganic fertilizer. Discernible variations in growth parameters of rice due to integrated N management were found in both the seasons over control. Integrated application of 50 per cent N via., Albizia lebbeck and remaining 50 per cent N via., inorganic fertilizer recorded significantly highest average plant height (98.78 cm), tiller number (391.19 m-2), root length (24.10 cm), root volume (20.57 cc), LAI (4.8), CGR (11.58 mg m-2 day -1) and DMP (9921 kg ha-1).
