Abstract: The experiment was performed at the Department of Genetics and Plant Breeding, Field Experimentation Centre, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) during rabi 2019 to standardize the suitable mustard-specific treatment for priming (variety Sangam). Eleven different pre-sowing seed priming alongwith control (unprimed) was examined by sampling for 12 hours. viz., T₀-Unprimed (Control), T₁-Distilled water (DH₂O), T₂–Potassium Nitrate (KNO₃) 0.5%, T₃–Potassium dihydrogen phosphate (KH₂PO₄) 0.5%, T₄- Polyethylene Glycol (PEG6000) 5%, T₅–Coconut water2%,T₆- Panchgavya (2%), T₇- Manganese sulfate (MnSO₄)0.1%,T₈- Zinc sulfate (ZnSo4)0.1%, T₉- Naphthaleneacetic acid (NAA) 50 ppm, T₁₀- Indole-3-butyric acid (IBA) 50 ppm, T₁₁- Wood apple leaf extract (5%) and T₁₂- Mint leaf extract (5%). It was found that all pre-sowing seed treatments showed significant differences with control and the highest percentage of field emergence, plant height, and attributes of yield and yield for PEG₆₀₀₀ were observed. Pre-sowing seed treatment with PEG6000 and MnSO₄ showed maximum field emergence of mustard seeds and was found to be lowest in control seeds. Pre-sowing treatment (seed priming) that leads to a physiological condition allowing the seed to germinate more effectively and no costly equipment and chemical requirements could be used as a simple method for overcoming weak germination and seedling establishments and helps to preserve agriculture which is economical, non-toxic, eco-friendly.
