Abstract: The present investigation entitled “Role of seed priming on biochemical changes and NPK uptake of rice (Oryza sativa L.)’’ was carried out in kharif season, during 2014 at the student instructions farm, Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (U.P.) India. The experiment was laid down in randomized block design with three replications on rice. The seed priming treatments were comprised of priming with 5 chemicals at 1% concentration viz (KNO3, KH2PO4, Ca(NO3)2, KCl and Na2S2O3) along with untreated control and hydro- priming. Seed priming was done for 24 hours. Observations were recorded at 20, 40, 60 and 80 DAT. The observations were taken on biochemical changes like Chlorophyll content and Catalase activity in leaf while NPK uptake was recorded in plants at maturity. All the Chemicals (KNO3, KH2PO4 Ca(NO3)2, KCl and Na2S2O3) influenced biochemical changes and NPK uptake positively however, the effect of KH2PO4 @ 1% was found most effective and significantly increased chlorophyll content, catalase activity and NPK uptake.
