A field study was conducted at university of agriculture Peshawar-Pakistan with the purpose of to investigate the influence on different seed priming techniques on different maize hybrid genotypes. The experiment was carried out in randomized complete block design (RCBD) replicated four times. Two factors experiment was performed i.e. sources of priming (Control, hydro, solid matrix priming, osmo-priming with PEG-6000) and maize hybrids (Gorilla, Pioneer 3025, CS-220). All priming techniques was done for 24 hours. Results of the experiment shows taller plants (227 cm), leaf area plant-1 (3179 cm-2), maximum ear length (19.2 cm), grains ear-1 (556.2 grains), thousand grain weight (331 g), biological yield (150778  kg ha-1), grain yield (5098 kg ha-1) and harvest index (33.9%) was recorded with osmo-priming (PEG-6000). In folder of maize hybrids more leaf area plant-1 (3131 cm-2) maximum ear length (19 cm), grains ear-1 (532.2 grains), thousand grain weight (327.8 g), biological yield (15065 kg ha-1) and grain yield (4564  kg ha-1) was recorded with CS-220. From the experimental results, it is concluded that CS-220 with osmo-priming (PEG-6000) is recommended for cultivation under the agro-ecological conditions of Peshawar Pakistan.
