Effect of different pre-sowing seed treatments on growth and seed quality parameters of maize (Zea mays L.)

The experiment was conducted in Post Graduate Laboratory, Department of Genetics and Plant Breeding, Sam Higg in bottom University of Agriculture, Technology and Sciences, Pryagraj (U.P.) during kharif season 2018, in order to standardize the best method of priming specific to Maize (var. HQPM-5). Four methods of priming viz., hydropriming, magnetopriming, halopriming, and organic priming with control (Unprimed) were evaluated by screening different duration (30, 60, 90, 120 minutes and 12 hours) and different concentrations (50 mt, 100 mt, 2% and 5%) viz., T0-Unprimed (Control), hydropriming - T1-Distilled water (12 hours), magnetopriming- T2-Magnetic field (50 mt) @ 30 minutes, T3-Magnetic field (50 mt) @ 60 minutes, T4-Magnetic field (50 mt) @ 90 minutes, T5-Magnetic field (50 mt) @ 120 minutes, T6-Magnetic field (100 mt) @ 60 minutes, T7-Magnetic field (200 mt) @ 60 minutes, halopriming- T8– Potassium Chloride (KCl) 2%, organic priming- T9- Tulsi leaf extract (5%), T10- Neem leaf extract (5%). It was found that all the priming treatment showed significance difference with the control and the highest germination percent, seedling length, seedling fresh weight, seedling dry weight, vigour indices were observed formagneto priming - Magnetic field (50 mt) @ 60 minutes. Highest germination was observed in Magnetic field and KCl. Seed priming, 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 and helps in sustaining agriculture and cost effective and economic, non-toxic, ecofriendly sources. | Effect of different pre-sowing seed treatments on growth and seed quality parameters of maize (Zea mays L.)
