A field experiment was carried out in Al-Fadhiliya city, Dhi Qar province during the winter agricultural season 2019-2020 to find out the effect of stimulation (soaking) wheat seeds with gibberellin and use of mineral and nano fertilization on some growth and yield characteristics of the Ibaa variety 99. Using RCBD Design with split plot arrangement with three replications. The first factor (main plot) included fertilization levels (F) mineral fertilizer recommendation for N, P ( F1 ), Nano fertilizer recommendation for N, P ( F2 ) and 0.5 mineral fertilizer recommendation + 0.5 Nano fertilizer recommendation ( F3 ).The second factor (sub plot) included the seed stimulation levels (drenching) with gibberellin (G) for 12 hour: 0.0 mg.G.L -1 (water only) ( G1 ), 50 mg G.L -1 (G2), 100 mg G.L -1 (G3). The results showed superior the level of fertilization (F3) in traits (plant height 110.33 cm, flag leaf area 54.45 cm 2 , number of tillers 389.00 tiller.m -2 , number of grains per spike 67.11 grain.spike -1 , grain yield 7.589 t.ha -1 ). While, the level of fertilization (F2) exceeding in adjective (weight 1000 grain 49.18 g). However, the level of stimulation (G2) superior in traits (plant height 106.00 cm, flag leaf area 54.267 cm - 2 , number of tillers 381.44 tillers.m -2 and the total grain yield 7.344 t.ha -1 ). Whereas, the level of stimulation (G3) exceeding in adjectives( number of grain per spike 71.22 grain.spike -1 and weight 1000 grain g). Interaction treatment (F3G2) gave the highest average of total grain yield by 8.133 t.ha -1 .
