The experiment was conducted in field experiment centre; Department of Genetic and Plant Breeding SHUATS Allahabad UP during kharif season 2016, in order standardize the best method of priming specific to pigeonpea Bahar variety. Seed priming using various method like that viz., hydropriming, helopriming and osmoprimong, biopriming were evaluated by screening a range of duration and concentration viz.,T0 Control, hydropriming, osmopriming- PEG (20%), helopriming (KCl 1%), (CaCl2 1%), bioprming (Neem leaf Extract 5%) and (Eucalyptus extract 5%) for 14 hours. It was found that all the priming treatments showed significance difference with the control and the highest field emergence percent and plant nodulation characters were observed for PEG6000 priming highest nodulation was observed in PEG 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, eco-friendly sources.
