Abstract: 
In order to evaluate the effect of wheat stubble disposal practices during fallow period on wheat yield, protein content, and soil properties, a field study was conducted on a clay loam soil at the Ghamlo station in Kurdistan Province. The experiment was arranged as a Randomized Complete Block Design with four replications. There were five treatments of stubble disposal practices, including control or stubble standing (A1), stubble removing (A2), stubble incorporated into soil (A3), stubble chopped and incorporated into soil(A4), and stubble burning (A5). Besides, two levels of nitrogen fertilizer, including 30 and 60 kg N/ha as Urea were applied in 3 wheat-fallow rotation periods. The results showed that stubble management had significant effect on grain yield, stubble yield and TKW. TreatmentA4 with 1543 kg/ha of grain yield, 3273 kg/ha of stubble yield and 40.7g of TKW was the best treatment. Nitrogen effects were significant on grain and stubble yield but were not significant on TKW. Therefore, N30 treatment was better than N60. Also wheat stubble management practices had positive effects on soil nitrogen and sulfate, grain protein and soil infiltration rate. Treatments A3 and A4 with soil nitrogen contents of 18.44 and 17.19 mg/kg, sulfate contents of 24.42 and 24.45 meq./liter, grain protein contents of 11.77 and 12.06 percent, and cumulative infiltration of 16.05 and 18.74 cm, respectively, were the best treatments in the experiment. Interaction effects of wheat stubble management practices and nitrogen levels were significant on grain yield, straw yield and TKW, such that A4B2, with grain yield of 1678 kg/ha and stubble yield of 3525 kg/ha was the best treatment, and A4B 1, with TKW of 41.07 g, was the best treatment with regard to grain size.
