Research was carried out to determine the effects of different nano-sulfur applications on yield and some plant properties of bread wheat during 2016-2017 winter growing season in Isparta/Turkey. Bread wheat cultivar of ʻKoç 2015ʼ was used as a plant material. The nano-sulfur (particle size 20 nm) was supplied by New Systems Petrol Products Import and Export Manufacturing Company. Five different applications control (CA), application to soil (SA), seed coating (SC), seed coating+application of booting stage (SC+BA) and seed coating+application of heading stage (SC+HA) were examined. The experiment was conducted to completely randomized block design with three replications. Results showed that the effect of nano-S applications were significant in all of examined traits (emergence rate, mean emergence time, plant height, spike length, kernel number per spike, grain yield, protein rate and sedimentation value). Nano-sulfur applications in bread wheat have had positive effects on all the examined traits. Mean values of examined traits varied for emergence ratio 75.0-100.0%, mean emergence times 2.35-2.83 days, plant height 68.7-73.7 cm, spike length 8.37-9.92 cm, kernel number per spike 35.55-39.50, grain yield 3431-3911 kg ha-1, protein ratio 13.29-14.57% and sedimentation values 38.20-48.70 ml, respectively. In particular, nano-sulfur application in seed coating+booting period resulted in 14% grain yield increase compared to control.
