Abstract

Background and objectives: Arid climate condition of the country, no proper crop rotation, collection, and burning of crop residue, over dose application of chemical fertilizer and not application of organic fertilizer caused to decreasing in soil organic matter that the yield and the soil fertility decreased. Crop residue is one of the most important conservation tillage factors for improving soil properties. Crop residue is the source of biofuel and industrial production. Residue removal has negative effect on crop production and environment. Result of experiment showed that residue removal affect soil organic carbon and this effect was more obvious when high amount of residue removed.Material and Methods: In order to investigation the effect of different RESIDUE TYPE and management and nitrogen on growth characteristics and yield of durum wheat (Triticum durum), an experiment was conducted at Agricultural Faculty of Shahid Chamran University of Ahvaz in 2012-2013. The experimental design was completely randomized block design, with three replications. The first factor was RESIDUE TYPEs (wheat and canola), second factor was residue management (residue burning, residue moving and 30% residue incorporated to the soil) and the third factor was different nitrogen resources (100% urea, 50% urea + ALKAZOTPLUS and sulfur seed coated urea). The measured traits were grain yield and protein and nitrogen, phosphorus and potassium of soil and plants. The Behrang cultivar was used with 350 plant m-2 density in 2×3 m plots. The harvest operation was on April, 2015 after ripening. Results: The results showed that the highest grain yield (6.92 t ha-1) was achieved at 150 Kg ha-1 urea and canola burning residues. Also the highest grain protein (15.25%) and nitrogen (2.61%) were observed at canola residue incorporated to the soil and sulfur seed coated urea. The highest grain phosphorus and potash content obtained at biological and chemical combination fertilizers + wheat residue removing and wheat residue incorporated to the soil + sulfur seed coated urea, respectively. Also the results revealed that the residue incorporated to the soil had positive effects and caused to more availability of the soil nutrients. The highest soil nitrogen and phosphorus were obtained at canola residue incorporated to the soil+ 150 Kg ha-1 urea fertilizer. Also the combination of biological and chemical fertilizer + canola residue incorporated to the soil had the highest soil potash contents.Conclusion: In general, the crop residue incorporated to the soil had positive effects on measured traits and concluded to increased soil nutrient availability. The highest soil nitrogen and phosphorus were obtained at canola residue incorporated to the soil+ 150 Kg ha-1 urea fertilizer. The canola residue incorporated to the soil+ combination of chemical and biological fertilizer treatments had the highest soil potassium contents. Although residue burning caused to uptake the soil nutrients in short term, but in long time, the disadvantages of this is more than advantages that it concluded to destruction the soil structure and decreasing in grain yields.
