Online published on 9 March, 2021. Abstract Alab trial was conducted to assess the effect of seed invigoration treatment with Mg (NO3) salts over short term moisture induced by PEG-6000 on percent inhibition of germination, length, fresh and dry weight of shoot and root and increase and decrease of same over the range of moisture stress as compare to control. Elevated levels of PEG-6000 were applied to create a range of moisture stress viz. 1.5, 2.5, 3.5 and 4.5% alone and along with invigorated seed. Percent inhibition of germination increased along with increasing the level of moisture stress while the length of shoot and root (cm), fresh and dry weight of shoot and root and declined as the concentrations of PEG-6000 increased from 1.5% to 4.5% as compared to control. The ameliorative effect was observed very clearly while comparing the performance of control set with highest level of moisture stress (4.5% PEG-6000 alone) and control with highest level of moisture stress (4.5% PEG-6000 + nitrate invigorated seed) on various parameters i.e. length, fresh and dry weight of shoot and root of maize seed. These results indicate that the performance of maize seeds were improved while growing with seed invigoration treatment with Mg(NO3)2 under the various range of moisture stress.
