Abstract

Organic material is one of the main soil components and has a big role in the improvement of soil cultivation. To determine the effect of WHEAT residue on seed yield and its components, this experiment was carried out as split-split plots under a complete blocks design with three factors and four replications at Research Field, Department of Agronomy and Plant Breeding, College of Agriculture, Shahid Chamran University in Ahvaz. This experiment was done with the same treatments as the last year, but with a few changes. In this study, treatments were: I-Planting methods of WHEAT by ordinary method after mixing PLANT RESIDUEs with soil, including: a1-WHEAT straw+canola. a2- WHEAT residue+barley, a3-WHEAT straw, a4-WHEAT residue, a5-WHEAT straw+barley, a6- burning WHEAT residue, a7-WHEAT residue+canola, an8-removing the whole residues of previous crop. II- The second factor was chemical FERTILIZERs in sub-plots including: b1- Chemical FERTILIZERs for high yielding (120 kg/ha P205, 125 kglha K20 and 137 kg/ha N), b2-chemical FERTILIZERs for medium yielding (72 kglha P205, 100 kglha K20 and 107 kg/ha N), b3-minimum chemical FERTILIZER applications based on current WHEAT seed production (40 kg/ha P205, 70 kglha K20 and 28 kglha N). The third factor that placed in sub-sub plots were varieties, including: cl-Chamran and c2-Atrac. In this experiment, barley and canola were planted as green manure. Also WHEAT straw and residue were mixture of whole straw produced in previous WHEAT plantation and mixing one-third of it with soil (removing the other two-thirds) respectively. The result showed that the highest seed yield was obtained for a7bl, a17b2,a6bl, a6b2 and a4b2 treatments. Also, the highest (0.824%) and the lowest (0.681) organic material were produced in a1 (WHEAT straw+canola) and a6 (burning WHEAT residues) treatments, respectively. Combination of PLANT RESIDUEs before planting with medium and high FERTILIZER levels increased the grain yield production and soil ORGANIC MATTER, but a4 (removing a part straw and mixing the PLANT RESIDUE) resulted in increasing of soil fertility and is recommended as a treatment of straw management to get higher grain yield.
