Title of the thesis:Effect of legumes on subsequent weed of cultivated cereals
Summary:The aim of this thesis was to evaluate weed plot of winter wheat following the pre red clover and alfalfa sown. The attempt took place in the cadastral municipality Žabčice in the South Moravian Region in 2011 and 2012. The evaluation experiment was used numerical method, the number of weeds were collected at 1 m2, with each option tillage and crop rotation in 24 repetitions. To assess the effect of environmental factors on the monitored individual weed species that occurred in the monitored plots were used for multivariate analysis of ecological data. The statistical evaluation of weed species and number of individuals were using a computer program STATISTICA.CZ. The results of the experiments it was found that higher weed even more species diversity was winter wheat after the previous crop red clover. Statistical evidence of higher incidence of weeds in crops of winter wheat after the previous crop red clover was in these weed species: Cirsium arvense, Consolida orientalis, Convolvulus arvensis, Descurainia sophia, Galium aparine, Lactuca serriola, Lamium purpureum, Polygonum aviculare and Trifolium pratensis. Statistical evidence of higher incidence of weeds in crops of winter wheat after the previous crop alfalfa was sown in these weed species: Medicago sativa, Stellaria media, Thlaspi arvense, Tripleurospermum inodorum, Veronica spills, Capsella bursa-pastoris, Fallopia convolvulus. Further, in an attempt to evaluated the effect of different tillage occurrence of weed species. The results show that minimizing tillage promotes higher rates of species: Medicago sativa, Veronica spills, Capsella bursa-pastoris, Papaver rhoeas. Traditional tillage affects a higher incidence of species: Chenopodium album, Thlaspi arvense, Viola arvensis, Stellaria media, Fallopia convolvulus, Lamium amplexicaule.
Key words:weeds, winter wheat, soil tillage, pre-crop
