The Experiment was conducted in the field of Department of Genetics and Plant Breeding, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) during Rabi season 2020-2021, in order to standardize the suitable pre- sowing seed treatment for Mustard. Different pre- sowing seed treatments with control (Unhardened) were evaluated viz., T0– Control,T1- Mg(No3)2 @ 0.1%,T2- Mg(No3)2 @ 0.3%,T3- Mg(No3)2 @ 0.5%,T4- Ca(No3)2 @ 0.1%,T5- KNO3 @ 0.5%,T6- Mg(So4)2 @ 0.1%,T7- Mg(So4)2 @ 0.3%,T8- Mg(So4)2 @ 0.5%,T9- GA3 @ 25ppm,T10- GA3 @ 50ppm,T11- GA3 @ 75ppm,T12- PEG6000 @ 25ppm. It was found that the all pre-sowing seed treatments showed significance difference with control. Seed treatment with KNO3 @ 0.5% found to be highest in field emergence and yield attributes of Mustard and it was followed by GA3 @ 25ppm and Mg(No3)2 @ 0.1%. Pre- sowing seed treatment with KNO3 @ 0.5% and GA3 @ 25 ppm showed maximum increase yield of mustard seeds and found to be lowest in control seeds. Pre-sowing seed treatments of the mustard seeds in which KNO3 @ 0.5% gave best result to enhanced germinability, seed vigour, seed yield and yielding attributes. These conclusions are based on the results of six months investigation and therefore further investigation is needed to arrive at valid recommendations.
