Abstract

The experiment was performed in order to comparison of ecological and chemical management methods on the emergence, growth and development of the potato weeds in 2015 on the two locations of agricultural research stations Alarogh and Samian in Ardabil province in a randomized complete block design with three replications. The treatments was included. 1. ) between rows of potatoes sprayed with Trifluralin herbicide. 2. ) between the rows of potatoes sprayed with Metribuzin herbicide. 3. ) cultivation practice. 4. ) usage of plant mulch contain the wheat stubble. 5. ) usage of plant mulch contain the Canola stubble. 6. ) usage of black polyethylene sheets mulch. 7. ) usage of transparent polyethylene sheets mulch. 8. ) weed infested (interference) treatment. 9. ) weed free (control) treatment. Based on the results obtained in this study, mulch, herbicide and cultivator were significant effects on the potato weeds density in both locations so that the least density of weed obtained in wheat stubble mulch and then usage of Metribuzin herbicide treatments, respectively. Most weed density was counted in the weed interference treatment equal to 99. 1 plants per square meter. The usage of wheat mulch compared to the non-application, reduced to 84 percent of weed density compared to weed interference treatment in potato crop. The application of Canola stubble residues compared to weed interference treatment reduced the weed density as 79 percent. The broad leaf species of Common Amaranth, Bindweed and Common lambsquarters density, as important potato weeds in all herbicide treatments, mulch and cultivation, decreased compared to weed interference treatment. The most of Common Amaranth density was observed in black plastic mulch, Trifluralin and transparent plastic mulch treatments respectively. The Common lambsquarters was the highest density in Metribuzin herbicide and plastic mulch treatments in this study. So the Green foxtail had the highest density in usage of cultivation and the least of density was observed in black polyethylene sheets mulch, Canola mulch and wheat mulch treatments respectively. The highest tuber yield was related to Metribuzin, cultivator and Trifluralin treatments and the least tuber yield by approximately 83 percent was related to weed infested all season treatment then plastic mulch treatment with 47 percent. The weed management of plant stubbles, black polyethylene mulch and cultivation practice treatments could care yield of potato in damage. So that use of mulch, especially plant stubbles, compared with herbicide usage, in addition to lower cost, would be adequate weed control.
