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 Koc 2015 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.
