Abstract:
Field experiment was conducted at the Experimental Farm, Department of Agronomy, Faculty of Agriculture, Annamalai University, Annamalainagar to study the influence of nutrient management practices on transplanted rice for its nutrient uptake and productivity. The experiment was laid out in randomized block design. The treatment schedule consist of nine treatments <em>viz.</em>, T<sub>1 </sub>- Absolute control, T<sub>2</sub> - Recommended dose of fertilizer (120:38:38 kgs of N, P<sub>2</sub>O<sub>5</sub> and K<sub>2</sub>O ha<sup>-1</sup>, T<sub>3</sub> - 75% RDN through fertilizer + FYM @ 12.5 t ha<sup>-1</sup>, T<sub>4</sub> - 75% RDN through fertilizer + 25% N through <em>Sesbania rostrata</em>, T<sub>5</sub> - 75% RDN through fertilizer + 25% N through <em>Azadirachta indica</em>, T<sub>6</sub> - 75% RDN through fertilizer + <em>Azospirillum brasilense</em> soil application @ 2 kg ha<sup>-1</sup>, T<sub>7</sub> - 75% RDN through fertilizer + FYM @ 12.5 t ha<sup>-1</sup> + <em>Azospirillum brasilense</em> soil application @ 2 kg ha<sup>-1</sup>, T<sub>8</sub> - 75% RDN through fertilizer + 25% N through <em>Sesbania rostrata</em> + <em>Azospirillum brasilense</em> soil application @ 2 kg ha<sup>-1</sup>, T<sub>9</sub> - 75% RDN through fertilizer + 25% N through <em>Azadirachta indica</em> + <em>Azospirillum brasilense</em> soil application @ 2 kg ha<sup>-1</sup>. Dry matter production, NPK uptake and yield components <em>viz. </em>number of productive tillers m<sup>-2</sup>, grain yield and stalk yield were recorded and economics were also calculated. Among the treatments, the treatment T<sub>8</sub> - 75% RDN through fertilizer + 25% N through <em>Sesbania rostrata</em> + <em>Azospirillum brasilense</em> soil application @ 2 kg ha<sup>-1</sup> imposed to rice recorded higher values in dry matter production, yield attributes, yield, economics and NPK uptake without affecting the soil fertility
