Abstract:
Field experiments were conducted at Agricultural Research Station, Thirupathisaram during <em>rabi </em>season of<em> </em>2011-12 to study the effect of integrated nutrient management (INM) on rice under rice-rice-pulse cropping system. The treatments structure comprised <em>viz.,</em> T<sub>1</sub>- Control (No manures/fertilizers), T<sub>2</sub>- Organic manuring (<em>Sesbania aculeata</em> @ 6.25 t ha<sup>-1</sup>), T<sub>3</sub>- Inorganic Fertilization (NPK @ 150:50:50 kg ha<sup>-1</sup> for medium duration rice) and T<sub>4</sub>-Integrated Nutrient Management (<em>Sesbania aculeata</em> @ 6.25 t ha<sup>-1</sup> + NPK @ 150:50:50 kg ha<sup>-1</sup>). Biometrics such as plant height, number of tillers hill<sup>-1</sup>, number of panicles m-<sup>2</sup>, number of grains panicle<sup>-1</sup>, panicle length, grain yield and straw yield were recorded.<em> </em>Integrated Nutrient management significantly influenced the growth and yield. The results revealed that treatment receiving application of <em>Sesbania aculeata</em> @ 6.25 t ha<sup>-1</sup> + 150:50:50 kg NPK ha<sup>-1</sup> for medium duration rice TPS 3 recorded relatively higher growth, yield and economics than other treatments.
