Abstract :

In order to evaluate how chemical control of weeds growing Yi and after the mechanical stage in the city Khodabande potato experiment in a randomized complete block design with four replications and treatments were: 1. Snkur (recommended dose), 2. Titus (dose recommended), 3. Epirus (recommended dose), 4 Snkur + Titus (25% of the recommended dose), 5 Snkur + Titus (50% of the recommended dose), 6 Snkur + Titus (75% of the recommended dose ), 7. Snkur + Epirus (25% of the recommended dose), 8 Snkvr + Epirus (50% of the recommended dose), 9 Snkur + Epirus (75% of the recommended dose), 10. Titus (25% of the recommended dose ), 11. Titus (50% of the recommended dose), 12. Titus (75% of the recommended dose), 13 Epirus (25% of the recommended dose), 14 Epirus (50% of the recommended dose), 15 Epirus ( 75% of the recommended dose), 16 weed control, weed control factors were studied 17 weed species, potato plant height, number of leaves on the plant, total dry weight of air split, underground dry weight step 30 days after the second spraying poison (after the mechanical plant), and harvest: tuber yield, total biomass plant, tuber number per plant, tuber weight were measured. Based on the results, treatment Titus (recommended dose) in terms of bindweed and amaranth in the highest group were statistically numerically, although it has a dry weight of less than weed density was reduced doses according to the comparison showed that the average yield of herbicide Epirus recommended dose (57/27 tons per hectare) no significant difference in weed control though numerically less than it was, among herbicide treatments reduced dose of Snkur + Epirus (75% of the recommended dose), Snkur + Epirus (50% dose recommended) and Snkur + Titus (50% of the recommended dose) produced, respectively, 52/24, 35/24 and 10/24 tons per hectare in the same statistical that would have been acceptable performance and herbicide Titus 75% of the recommended dose produced a numerically 60/15 tons per hectare is the lowest yield.
