Seed priming is an effective and shortgun approach to improve the emergence and stand establishment of field crops. Impact of priming on the germination and seedling vigour of mung bean (CM-97) were tested under laboratory conditions. The seeds were soaked in water (hydropriming), solutions of KH2PO4, Manitol, Polyethylene glycol (PEG6000), Na2MO4.2H2O (osmocoditioning) and salicylic acid (SA) (hormonal priming).having two levels for each chemical (treatment). After giving all the priming treatments by soaking seeds for five hour, seeds were dried and sown in petri dishes in growth chamber at 27 ± 2 o C for seven days. All the treatments significantly improved the germination percentage, root and shoot length, seedling dry weight and seedling vigour index (SVI) while time to fifty percent seeds to germinate (T50) and mean germination time (MGT) decreased, significantly. Osmopriming using P at 0.60% applied in the form of KH2PO4 significantly improved seed vigour and final germination percentage. The use of polyethylene glycol was expensive and gave similar results as for control (dry seeded). It is concluded that seed priming (osmo-priming and hormonal-priming) can be used as effective tool for invigouration of mung bean seeds, for vigour enhancement.
