Effect of Bio-Priming on Seed Quality Parameters of Rice (Oryza sativa L.)

This study investigates the impact of bio-priming with Azospirillum, Pseudomonas fluorescens, Phosphorus solubilizing bacteria (PSB), and Potassium solubilizing bacteria (KSB) on seed quality parameters of rice (Oryza sativa L.). Bio-priming is a sustainable agricultural practice that involves the use of beneficial microorganisms to enhance plant growth. Standardization experiment was done using 35 treatments in laboratory using Completely Randomized Design (CRD). The best performed 10 treatments were selected for field study. The field experiment was conducted in Randomized Block Design (RBD). The harvested seeds were further subjected to quality tests in the laboratory using Completely Randomized Design (CRD). Among different treatments, Azospirillum bio-primed at 10% and 12 hours of soaking and pseudomonas fluorescens bio-primed at 20% and 12 hours of soaking showed significant results for germination percentage, seedling vigour index, field emergence, highest seedling length.
