Abstract

The experiment was conducted in post graduate Seed Testing Laboratory Department of Genetics andPlant 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 Okra(VNR-Super Green). Different Pre-sowing seed treatments viz., T0-Control (Untreated), T1- Magnetic Field@ 100mt -15 Minutes, T2- Magnetic Field @200mt- 20 Minutes, T3- Electric Field @250mA-10 minutes, T4-Electricfield@300mA-15 minutes,T5-Nacl@0.2% -12 hours, T6 Nacl @0.3%-14hours, T7- Mgso4@0.3% for 4hours, T8- Mgso4@0.4%-8 hours, T9-zno @0.2%-6 hours, T10 Zno@0.4%-12 hours, T11- Ascorbic acid@0.3%-6hours, T12-Ascorbic acid @0.3%-8 hours. It was found that all the Pre-sowing seed treatments recorded thesignificant difference with that of control. In lab condition highest germination percentage, shoot length,root length, seedling length, fresh weight, dry weight, seed vigour index-I, seed vigour index-II was foundin T3-Electric @250mA-10 minutes. Pre-sowing seed treatment with electric @ 250mA-10 minutes followedby T12@0.3%-8 hours, Nacl@0.2%-12 hours significantly increased the germination percentage, shoot length,root length, seedling length, seed vigour index-I, seed vigour index-II of Okra seeds and found to be lowestin control seeds. Pre-sowing seed treatment leads to a physiological condition that allows the seed togerminate more effectively and no costly equipment and chemical requirements could be used. Hence it isa simple method for overcoming weak germination and seedling establishment and helps to preserveagriculture and economical, non-toxic, eco-friendly sources.
