TI  - Tillage, Crop Residue and Nitrogen Management Effects on Nitrogen Uptake, Nitrogen Use Efficiency and Yield of Rice
AB  - Field experiment was conducted in three factorial strip split plot design to evaluate the effect of twoestablishment methods (EM) i.e. transplanted in puddled soil (Pu-TPR) and direct seeded in zerotillage (ZT-DSR), two residue levels i.e. residue kept at 3 t ha -1(RK) and no residue (RR) with twonitrogen doses i.e. recommended dose (100 kg N ha -1) (RD) and farmers' dose (50 kg N ha-1) (FD)with six replications with individual plot size of 5.4 m × 6.3 m on rice variety Ramdhan during theyear 2016. Nitrogen uptake, nitrogen use efficiencies and yield of rice were recorded. Straw nitrogenuptake was significantly higher in ZT-DSR than Pu-TPR. Similarly, grain straw and total nitrogenuptake were significantly higher in residue applied and recommended dose of nitrogen than noresidue applied and farmers-nitrogen dose treatments respectively. Nitrogen efficiency ratio andphysiological efficiency index were significantly higher in Pu-TPR and no-residue appliedtreatments while partial factor productivity was higher in residue applied treatment. All nitrogen useefficiencies like partial factor productivity, nitrogen efficiency ratio and physiological efficiencyindex were significantly influenced by nitrogen dose and seen higher in recommended dose ofnitrogen. Establishment methods had no significant effect on grain yield but straw yield wassignificantly higher in ZT-DSR but harvest index was seen higher in Pu-TPR. Grain yield and strawyield were significantly higher in residue applied treatment and recommended nitrogen but harvestindex was higher in farmers-nitrogen dose.
