Effect of different tillage methods on the amounts of treflan upon parts production and production application seedling canola cultivar Hayola 401 in the climatic conditions of DEZFUL

摘要

Background: Weeds are unwanted plants that grow outside main location. In anotherdefinition, weeds are introduced plants that application is not yet known. Anotherdefinition of weed plant is planted to grow up unexpectedly in the fields and gardens.Since agriculture is the main uninvited guests who greatly reduces the quantity andquality of the economic value of the crop and also interfere with agricultural operationsraises production costs.Objective: In order to analyze the effect of different tillagemethods on the amounts of treflan herbicide controlling weed in experimental seedingcanola farms a test in the form of the factorial experiment was done as Randomizedcomplete Block design in 4 frequencies and 9 treatments in DEZFUL Agriculture andindustry Martyr Beheshti in farming year 2007-2008Results: Results of the test showedthat ratings of herbicide treflan on weed of Berseem- clover has been meaningful at alevel of 5 percent and hasn't been meaningful on several Bullwort weed, wild carrot,total weeds, dried weight of weeds, canola height, overall numbers of canola branches,harvest index, length of sheath, sheath seed number, weight of thousand grains, yield.different tillage methods on several Berseem clover and several weed of Bullwort, driedweight of weeds, yield and has been meaningful at a level of 1 percent and has beenmeaningful at a level of 5 percent of total weeds and hasn't been meaningful on severalweed wild carrot, weight of thousand grains, sheath numbers in canola plant, Length ofsheath, overall numbers of canola branches and harvest index. Conclusion: IN mutualeffect of treflan herbicides and tillage methods on several of Berseem clover andseveral Bullwort weed, total weeds, dried weight of weeds, yield has beer meaningful at1 percent level and hasn't been meaningful on several wild carrot, weight of thousandgrains, sheath numbers in canola plant, sheath length in canola plant, total numbers ofcanola branches, harvest index, the numbers of seeds in sheath, canola height.
