Abstract
In order to the study of grain yeld and morphlogical traits in dryland wheat cultivars, an experiment was carried out in factriol arrangement using randomized complete block desing with three replications at Agricultral Research Station of Ilam Unuversity during2013-2014 croping season. Experiment factors consisted of two dry land wheat cultivars (bread (Keras Sablan) and durum wheat (Saji)) and phosphorious deficiency, phosphate solubilizing bacteria and Mycorrhiza fungi treatment including (without application of phosphorious, 100% consumption of phosphorious fertilizer, phosphate solubilizing bacteria, Mycorrhiza fungi, phosphate solubilizing bacteria + Mycorrhiza fungi, 50% of phosphorious fertilizer + phosphate solubilizing bacteria + Mycorrhiza fungi, 50% of phosphorious fertilizer + phosphate solubilizing bacteria, 50% of phosphorious fertilizer + Mycorrhiza fungi). Results indicated that interacton effect between cultivar × bio-fertilizer had significant effect on spike.m-2, spikelet.spike-1, grains.spike-1, 1000-grain weight, grain yield, biological yield, harvest index, spike length, spike weight and plant height. Using of bio-fertilizer had positiveand significant effect total studed traits in two dryland wheat onder dry land condition so that Saji cultivar and Using of bio-fertilizer had the heighest grain yield with 62% to check treatment (without using of phosphrious chemical fertilizer and f bio-fertilizer) and also Increasing of 36% observed to 100% of using of phosphrious chemical fertilizer. Therewas significant different between cultivars to respose of Using of phosphate solubilizing bacteria and mycorrhizal fungi, so that Sji cultivars had the best reponse to mycorrhizal fungi. Therefore with regard to cultivation of wheat is facing to terminal stresese (drought and heat), indicated that Saji cultivar and Using of mycorrhizal fungi can be the best result under dry land conditions.
