Title : Standardizing the crop establishment methods, NPK fertilizer levels and weed management practices for enhanced growth and yield optimization of paddy-rice

Abstract :

The sustained rice yield plays an important role in the country’s GDP. Nowadays the key factors for enhanced growth and optimized yield of rice are often related to an appropriate crop establishment method (CEM), efficient nutrient fertilizer management (NFL), and sensible weed management practice (WMP). And therefore, the prime objective of this study was to standardize the CEM, NFL and WMP for sustained the optimized growth and yield of hybrid rice. The results disclosed that puddled transplanting rice (TPR) significantly enhanced rhizospheric and phyllospheric growth (plant height, tillers m-2, DMP, CGR, LAI, LAD, root volume and root biomass) and produced a significantly higher yield than un-puddled transplanting rice (UTPR) and dry direct seeding rice (DDSR). Application of 100% NFL registered the better growth with sustained yields though remained statistically identical with 125% NFL and both showed significant superiority over 75% NFL applied to the crop. However, herbicide layering (CW) of bispyribac-sodium 20g a.i. + pyrozosulfuron 20g a.i. was sprayed at 20 DAS/T in rice field had effectively controlled the weed flora associated though produced slightly a lesser yield productivity when compared to weed-free (HW) and both exhibited the maximum phyllospheric and rhizospheric growth with sustained yield over other two WMPs nonetheless failed to prove more remunerative than brown manuring (BM).
