The present research was conducted in order to investigate the effect of organic nanofertilizer and fulvic acid on yield, amino acids composition and protein percentage of wheat grain under water deficit conditions, as a split plot factorial based on randomized complete block design with three replications during growth seasons of 2023- 2024 in the farm of the Research and Education Center for Agriculture and Natural Resources in Ardabil province (Moghan). The treatments was include irrigation as the main factor in three levels (without irrigation (rainfed), supplemental irrigation at the stage of clustering and full irrigation) and secondary factors including of seeds priming with organic nanofertilizer (without application and application of seeds priming with a concentration of one per thousand) and spraying fulvic acid with concentrations (0, 5 and 10 grams per liter) at the time of tillering, flowering and seed filling and two cultivars of wheat {irrigated cultivar (Taktaz) and rainfed cultivar (Aftab)}. The variance analysis of the data showed that the main effect of the experimental treatments was significant in all traits. The triple interaction of irrigation × cultivar × organic nanofertilizer priming on the content of essential amino acids studied (valine, isoleucine, leucine, threonine, methionine, lysine and phenylalanine) was significant. The highest content of essential amino acids in the treatment combination without irrigation × seeds priming with organic nanofertilizer × Aftab cultivar was 6192.55 mg/100 grams and the lowest in the treatment combination full irrigation × without application of seeds priming with organic nanofertilizer × Taktaz cultivar was 3638.85 mg/100 grams. The treatment without irrigation had the highest (16.64%) and the full irrigation treatment had the lowest (13.56%) percentage of seed protein. The interaction of irrigation × organic nanofertilizer priming × fulvic acid foliar spraying in both cultivars caused a significant increase in grain yield compared to the control treatment. So that the highest content of seed yield was obtained in treatment combination full irrigation × seeds priming with organic nanofertilizer × foliar spraying of fulvic acid with a concentration of 10 grams per liter × Taktaz cultivar at the rate of 6082.25 kg/hectare. Therefore, it is recommended to use organic nanofertilizer priming and foliar spraying of 10 grams per liter of Fulvic acid in order to increase the content of amino acids, grain protein percentage and yield of wheat crop in different irrigation conditions in these regions and similar climates.
