Management of cover crops of cold cereal, on total fresh weight, total dry weight weed, yield and yield components peppermint

To study the effect of cover crop and how manage cover crop an experiment was conductedin Agricultural Research Center of University of Mohaghegh Ardabili , theexperiment was factorial based on complete randomized block design withthree replications. winter cover crops and spring cover crops as the main factorwith six levels( winter wheat, spring wheat, winter barley , spring barley,winter rye, winter rye+ winter barley) and how manage cover crop with three levels(living mulch, heading mulch, mulch with herbicide) as a second factor. Forcomparison, two controls (without cover crop with weeding weeds andwithout cover crop without weeding weeds) was aside experiments. The resultsshowed that main effect of type cover crop on the number of branches, leaffresh weight, leaf dry weight of peppermint and also the total dry weight ofweeds and at the first stage of sampling, Had a significant impact. The maineffect of management was significant for all traits measured. However, theinteraction of cover crop in how management cover crop were not significant.Winter wheat highest number of branches, leaf fresh weight, leaf dry weight ofpeppermint, relative to other levels of cover crops. In the first stage sampling isobtained by winter rye, the lowest total weed weight relative to other levels.Spring barley, winter rye the lowest total weed dry matter to create than othercover crop. All three methods to manage of cover crops the most affected by weeds dryweight compared to control. (no weeding and no cover crop weed)
