“…Moreover, it is cost-effective, environmentfriendly and easy to apply. Large groups of priming agents are known that perform effectively under a wide range of climatic conditions in favor of morphological, physiological, biochemical, and molecular alteration in various crops i.e., hydropriming, Ca(NO3), NH4(SO4 )2, NaCl, KCl, KH2 PO4, CaCl2, ZnSO4: Salicylic acid, MgSO4, GA3, KNO3 Mg (NO3)2 (10)(11)(12). Optimizing the priming chemicals concentration in relation to knowing the sequential event of the metabolic process of maize plant at the molecular level under drought conditions is most needed.…”
