The present investigation was carried out at S.V Agricultural College, Tirupati to know the effect of seed priming on biochemical parameters of dry direct sown rice (Oryza Sativa L.). A laboratory experiment was conducted in completely randomized design and replicated thrice with six popular aerobic rice genotypes i.e. MTU 1010, MTU 7029, JGL 20171, NLR33671, MTU 1075 and MTU 1112. Rice seeds were subjected to different concentrations of gibberillic acid with, 200, 500 and 1000 PPM and combination of both gibberillic acid and KNO3 treatments i.e. GA3 (200PPM, 500PPM, 1000PPM + KNO3 @3%), KNO3 @3% and control (Hydropriming/Water soaking), in order to know the effect of seed priming (Gibberllic acid and KNO3) on various biochemical parameters like Reducing sugars (mg/g), Starch (mg/g) and Alpha amylase (%) activity were recorded at 2, 4 and 6 DAT. The results revealed that in all the biochemical parameters among Varieties MTU 1010, JGL 20171, NLR 33671 had recorded higher amount of reducing sugars, starch and Alpha amylase activity compared to MTU 7029, MTU 1075 and MTU 1112. Among treatments 1000 PPM GA3, GA3 (200 PPM, 500PPM, 1000PPM+KNO3@3%) are found to be best.
