One of the main challenges in today's society is the issue of food security supplies. Which is also a direct function of available water resources. On the other hand, the imbalance between supply and demand of water consumption has doubled the need for optimal and sustainable use of renewable and non-renewable resources. In order to, increasing the water use efficiency and productivity of wheat is considered as a practical and executive solution. In this regard, four bread wheat cultivars (Haydari, Pishgam, Mihan and Orum) were examined under different irrigation systems (sprinkler, tape and subsurface) while examining their morphological, quantitative and qualitative characteristics and traits, In Shahrekord Chahartakhteh research station using split plot experiment in the form of a randomized complete blocks statistical design, in which irrigation systems, main factor in larger plots (main plot) and wheat cultivars, sub-factor in smaller plots (sub-plots) in three replications, was implemented. In this project, the volume of water given (According to FAO Publication No. 56 and the soil profile of the root zone) were measured to tape and subsurface irrigation systems by Volumetric meter and sprinkler irrigation system, water height on ground surface and calibration sprinklers. Yield of produce produced in different irrigation systems along with morph physiological characteristics of different wheat cultivars (planting date, germination, tillering, plant height, number of spikes per plant, number of seeds per spike, number of spikelet per spike, peduncle length, length of radicle and Biological yield) were calculated. Also, after harvesting, the quality characteristics of the produced wheat (initial germination percentage, final germination percentage, daily germination rate, seed and seedling vigor) were calculated. The results of two-year average showed that the effect of irrigation systems on the number of germinated seeds in 4 days, number of normal seedlings, peduncle length, 1000-seed weight, biological yield, grain yield and water use efficiency index at 1% level and number of plants per square meter, number of spikes per plant, per level 5% had a significant difference. The effect of cultivars on root plantlet, stem plantlet length, radicle length, 1000-seed weight, grain yield, biological yield and water use efficiency at 1% level had a significant difference. 1000-seed weight, grain yield and biological yield, water productivity index in Type irrigation system had higher yield than other irrigation systems, they had more yield and values and statistically different with a significant difference of 5%. The maximum yield was related to Haydari cultivar under tape irrigation system with 8616 kg / ha yield, and Orum cultivar under sprinkler irrigation system had the lowest yield (4995 kg / ha). Water productivity index were among tape, subsurface and sprinkler irrigation systems with values of 1.57, 1.24 and 0.93 kg/m3, respectively, and among Haydari, Pishgam, Mihan and Orum cultivars, respectively 1.33, 1.29, 1.28 and 1.09 kg per cubic meter. The minimum grain yield was in sprinkler irrigation (5766 kg / ha) and the highest was in surface tape irrigation (7830 kg / ha). The minimum water consumption was in tape irrigation (4995 m3/ha) and the highest was in sprinkler irrigation (6221 m3/ha). The maximum yield was related to Heydari cultivar in tape irrigation system with 8616 (kg / ha) yield, and the lowest grain yield was related to Orum cultivar under sprinkler irrigation system (4995 kg / ha). Therefore, based on the results among irrigation methods, tape irrigation systems and among the wheat cultivars tested, Heydari cultivar is suggested as the superior cultivar to continue all work and related matters.
