In the present investigation, two seed lot (one year old and freshly harvested) of chickpea variety PG 114 were treated with the strength of 100 and 200 mT (mili tesla) of magnetic field (MF) for one hour and for hydro-priming seeds were hydrated in tap water for 8 hours then dehydrated in shade upto original moisture content. Germination indices, seedling growth and enzymatic activities of treated chickpea seeds were evaluated along with untreated (control) seeds of both the old and freshly harvested seed lots. Germination indices and seedling growth were recorded significantly higher in seed treated with magnetic field of 100 mT while lowest increment was found in untreated seeds. Values of α amylase enzyme activity recorded in terms of mg of starch hydrolyzed per gram of seed were also significantly higher in magnetically seeds treated with 100 mT field for one hour. Seed invigoration treatments significantly improved membrane integrity over untreated seeds recorded in terms of electrical conductivity (EC) of seed leachates.
