To evaluate the response of saffron to animal manure, and biological chemical fertilizer in an arid climate, experiment was performed as split plots based on a randomized complete blocks design with three replications during consecutive crop growth seasons (2015-2018) at Research Farm University Gonabad, Iran. The experimental treatments included application (60 t ha-1) non-application (control) manure main plot use biosulfur (5 kg ha-1), biophosphate (3 L nitroxin (150, 100, 100 ha-1 urea, triple superphosphate, potassium sulfate, respectively), no sub-plot. results showed highly significant quantitative traits which increased leaf, flower, corm indices by mean 15.1-35.7% than control. interaction effect fertilizers for weeds significant. There difference between biophosphorus most mentioned years. simultaneous these average about 60, 105, 135, 110, 165, 55% leaf dry weight, number flowers, fresh flower yield, stigma weed weight saffron, respectively compared or terms related so fertilizers, control, replacement size, bud per by, respectively, 35, 40% average. improved content crocin, picrocrocin, safranal stigma. best were obtained from although observed this treatment treatments. Overall, three-year show very high plant and, therefore, it is possible replace organic cultivation implement agriculture achieve acceptable qualitative yields areas similar location.
