Abstract:
Cowpea is an important leguminous crop is believed to be originated in Central Africa. It is self-pollinated annual herb with a wide range of growth habit and response to photoperiod. The fortification of seeds for better Growth and Yield has become important and emphasized. The study was conducted to determine - Effect of different invigoration treatments on growth and yield parameters in Cowpea (Vigna unguiculata L.) The experiment was conducted in post graduate Seed Testing Laboratory and field, 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 Cowpe (Vigna unguiculata) Experiment conducted different invigoration treatments with control (Unhardened) were evaluated by screening 8 hour viz., T0 –Control, T1 – PEG6000 @ 3%, T2 – PEG6000 @ 5%, T3 – CaCl2 @ 3%, T4 – CaCl2 @ 5%, T5 –GA3 @ 50 ppm, T6 – GA3 @ 100 ppm, T7 – KH2PO4 @ 0.5%, T8 – KH2PO4 @ 1%, T9 –Vermiwash @ 5%, T10 – Vermiwash @ 10%, T11 – (NH4) Moo4@ 0.3%, T12 – (NH4) Moo4@ 0.5%.
