Abstract

Now a day winter cover crops planting has been attended to reduce herbicide application. An experiment was carried out at the Research Farm of Agriculture Faculty, Bu- Ali Sina, University, in 2009. The experiment was a randomized complete block design with three replications. The trial included of five treatments consists of no cover crop, RYE, winter OILSEED RAPE, BARLEY and TRITICALE. The results showed that winter cereals were produced more biomass than winter OILSEED RAPE. living mulch of RYE, BARLEY, OILSEED RAPE and TRITICALE reduced winter weeds biomass 89, 86, 82 and 70 percent respectively, in compare to control. Cover crop treatments showed significant different weeds control of potato at 3 time (15, 45 and 75 DAPG) compare to control treatment. Residues mixed to soil of OILSEED RAPE and RYE had the most inhibition affects on summer weeds. These treatments, average weeds biomass decreased 61 and 57 percent respectively, in compare to control. OILSEED RAPE and RYE in compare to control reduced weeds density in potato 36 and 35 percent, respectively. Significant negation correlations of weeds plant population, weeds dry matter with average tuber weight and potato YIELD. The treatments, OILSEED RAPE and RYE in compare to control increased tuber YIELD of potato 54 and 50 percent, respectively. These treatments, the average tuber weight increased 74 and 38 percent in compare with control, respectively.
