Seed priming - one small step for farmer, one giant leap for food security: II mechanism and manifestation

Seed germination, emergence and crop growth are often constrained by multiple environmental stress under field condition limiting productivity. priming, a age old inexpensive technique, consisting of soaking seeds in priming agent prior to sowing, has been applied different crops conditions with varying degrees success. To understand the significance this potentially transformative agronomic strategy, we have reviewed here detailed mechanism seed at physiological molecular level along secondary metabolite production. significant positive impact on health, yield, mitigation biotic abiotic stresses irrespective its methods such as hydropriming, on-farm halo-priming, osmopriming, osmo- hardening, hormonal matrix nutripriming or bio-priming. This technology could be effectively adopted strategy increase food security commercial agriculture.
