Drought stress affects various physiological and metabolic processes in rice (Oryza sativa L.) plant. Non-availability of high-yielding varieties suitable for cultivation under drought condition lead to sharp decline in rice yield. The current study was aimed to carry out to assess the impact of PPFM and plant growth promoters on mitigating drought stress effects in semi dry rice. Field experiment was carried out in semi dry rice variety ADT 45 along with foliar spray different plant growth promoters like PPFM (500 ml ha-1), brassinolide (1 ppm) and salicylic acid (100 ppm) under semi dry condition. The study indicated that the PPFM and plant growth promoters could effectively improve drought tolerance capacity of rice under semi dry condition. PPFM and different plant growth promoters was found to be superior in improving SPAD value and proline content. The antioxidant enzyme, catalase activity was enhanced by PPFM (500 ml /ha) and brassinolide (1 ppm) treatments which had the ability to protect the plant under abiotic stress by nullifying oxidative damage. Foliar spray of PPFM (500 ml ha-1) was found effective in improving the NR activity followed by brassinolide (1ppm).
