The experiment was conducted in post graduate Seed Testing Laboratory, Department of Genetics and Plant Breeding, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) during Kharif season 2019-2020, in order to standardize the suitable pre-sowing seed treatment of Cowpea (var). Pre-sowing seed treatments with control (Unprimed) were evaluated by screening 12 hour viz., T0 – Control, T1 – DH2O, T2 – PEG6000 @(2%), T3 – Mannitol @ (2%), T4 – GA3 @ (100 ppm), T5 – SA @ (100 ppm), T6 – IBA @ (100 ppm), T7 – KCl @ (2%), T8 – KNO3 @ (2%), T9 – CaCl2 @ (2%), T10 – Curry leaf extract @ (5%), T11 – Moringa leaf extract @ (5%), T12 – Neem leaf extract @(5%). It was found that all the pre-sowing seed treatments showed significance difference with the control and in laboratory condition highest germination per cent, seedling length, seedling fresh weight, seedling dry weight, vigour indices were observed for T2- PEG6000 (2%). In field highest field emergence percentage observed in T5- SA (100 ppm) and Plant height highest observed in T4 – GA3 @(100 ppm), number of pods per plant, seed yield per plant, seed yield per plot, biological yield, harvest index was observed for T2- PEG6000 @ (2%). Observed highest germination and yielding parameters in PEG6000 @ (2%). Pre-sowing seed treatment with PEG6000 enhance germinability and seedling character, its simplicity and no requirement for expensive equipment and chemical could be used as a simple method for overcoming related to a poor germination and seedling establishment.
