Differential response of root morphology of rice (Oryza sativa L.) genotypes under different phosphorus conditions

The present study was conducted to evaluate the effect of phosphorus deficiency stress on root traits of diverse rice genotypes. Roots of rice genotypes grown in root rhizotron having soil P (P2O5 ≤ 7.59kg/ha), with and without P supplementation were compared for difference in total root length, lateral branching, surface area and volume.
