Root and Physio-Biochemical Parameters as Influenced by Phosphorus and Phosphorus Solubilising Inoculants in Rice

The present study was aimed to show the effect of phosphorus solubilising inoculants on CO 47 rice variety under the interactive effect of five different seed treatments and different Plevels. Among the treatments P₃S₃ (100% P + JumpStart 10E4) recorded higher root length and lower root-shootratio inallstages of the crop. Higher availability of P in soil under P₃S₃ treatment supported to attain maximum chlorophyll content (2.97 mg/g), photosynthetic rate (39.96 ìmol CO₂ m⁻² s⁻¹), PS II quantum yield (Fv/Fm ratio) (0.71) at 50% flowering stage compared to other treatments. Efficient root morphology and physio-biochemical parameters under P₃S₃ treatment attributed for higher yield (8250.2 kg ha⁻¹).
