Soaking of maize seeds in 5 and 7.5 mM Mg(NO3)2 Improved the germination and growth of radicle and plumule at 96 hrs. of germination. The soluble, insoluble and total nitrogen in plumule also increased. The insoluble and total nitrogen in the radicle however, decreased with increasing hrs. of germination. Plumule and radicle showed maximum activity of nitrate reductase with 7.5 and 10 mM Mg(NO3)2 treatments respectively.
