Author(s): S Natarajan and Guru G
Abstract: Field Experiments were conducted at the Tamil Nadu Agricultural University, Coimbatore in Kharif and Rabi seasons of 2011-12 and 2012-13 to find out the influence of different organic sources and inorganic N fertilizers on rice productivity and profitability. The integration of 50% N as organics through Sesbania aculeate with 50% N as inorganic (Urea) increased the yield by 24 percent in kharif and 25percent in rabi rice combination. The available N, P, K and organic carbon contents were increased in the above treatment as compared to 100% N as through inorganic alone. Application of 50% N through Seshania aculeata + 50% N as inorganic fertilizer gave higher net return and benefit cost ratio of Rs. 58261 and 62921 ha-l and 2.94 and 2.87 during 2011-12 and 2012-13 respectively in the kharif and rabi seasons.
