Radish (Raphanus sativus L.) which belongs to Brassicaceae family is a vegetable crop consumed for its roots. Soil characteristics have great effect on formation of roots having high quality. Radish is one of the most susceptible vegetables to salinity, if it is grown in heavy soils shape disorders and cracks of roots are occured. Sulphur is an element which has positive effects on plant growth and health. It is used for decreasing high soil pH, salinity and enhances soil structure. The aim of the study was to investigate the effects of diffferent doses (0, 10, 15, 20, 25 kg/da) of sulphur ("Sicostar" containing 90% sulphur and %10 bentonite) treatments on yield and root quality of "Balcalı" cultivar having round roots and "Ç.Ü. Seleksiyon No:2" genotype having long roots which were developed by Department of Horticulture, Faculty of Africulture, University of Cukurova using selection breeding. According to the research results, different doses of micronized sulphur with bentonite treatments increased total root yield, root weight, root length and root diameter however; except total plant weight, it is found that there was no statistical significance among applied doses on other measured parameters.
