Abstract: A field experiment was carried out during the winter (Rabi) season (2013-14) at Agricultural Research Farm, Banaras Hindu University, Varanasi to study the ameliorating effect of seed priming by salicylic acid on biochemical traits in maize genotypes i.e., HUZM-185 and HUZM-80-1 under normal and delayed sowing. The experiment was laid out in split plot design comprising eight treatment combinations in three replications. Seeds were primed with salicylic acid (SA) @ 20 µg mL^-1 and 40 µg mL^-1 along with hydro priming (distilled water) for overnight and non-primed seeds as control before both sowings i.e., normal and delayed sowing. Observations were recorded at 20, 40 and 60 days after sowing for total chlorophyll, total soluble sugar, protein and proline contents in leaves. It was found that for the studied biochemical traits, genotype HUZM-185 primed with 20 µg mL^-1 salicylic acid significantly increased in delayed sowing as compared to normal sowing. This finding suggests that maize genotypes were found to differ in their ability to respond to delayed sowing under influence of seed priming with salicylic acid.
