|Title of the thesis:||Effect of soil cultivation on weeds in winter wheat|
|Summary:||The object of the study was to evaluate the effect of soil tillage on weeds in cropstand of winter wheat (Triticum aestivum). The study was performed in a maize growing area. Winter wheat was raised by fore-crop alfalfa as well as by fore-crop silage maize. The soil was cultivated by three methods -- conventional tillage, minimum (reduced) tillage and no tillage. Monitoring of the trial was in progress in 2005 and 2006, findings in the number of all weeds and number of weed species were evaluate by LSD analyse and effect of some factors on weed species was evaluate by CCA - Canonical Correspondence Analysis. It was find out, that statistically conclusive effect on an amount of all weed species in winter wheat has only conventional tillage. The number of all weed individuum per square meter were under these circumstances the lowest. The highest number of all weeds was shown under no tillage. Number of weed species was statistically conclusive the lowest under reduced tillage, the highest again under no tillage. As result of CAA, conventional tillage seemed to be prefer by weed species like oriental knight's-spur (Consolida orientalis), black-bindweed (Fallopia convolvulus), fat-hen (Chenopodium album) or scentless mayweed (Tripleurospermum inodorum), under reduced tillage it was shepherd's-purse (Capsella bursa-pastoris), common chickweed (Stellaria media) or field pansy (Viola arvensis) and species, that seemed to prefer no tillage were for instance gallant soldier (Galinsoga parviflora), cleavers (Galium aparine), prickly lettuce (Lactuca serriola), smoth sow-thistle (Sonchus oleraceus) and others. The amount of weeds were statistically high conclusive higher in winter wheat, that followed by alfalfa. In case of reduced or no tillage is number of all weeds in winter wheat higher. The similar action causes also winter wheat raised by alfalfa. I would recommend to performed longer-term inquiry.|
