The influence of nitrogen on yield formatin of spring barley
The purpose of this diploma thesis was to find out the effect of a graduated dose of nitrogen fertilization on the revenue elements (number of plants per area, number offshoots per area, number of ears per area, number of grains inside one ear and weight of thousand seeds) of the spring barley. The field experiment was established in the spring of 2021 on a private family farm which belongs to Mr. Jaroslav Čech and it is located in Běleč near Mladá Vožice. Spring barley of the Bente variety was sown in the experimental field. The experimental doses of nitrogen fertilization were determined as follows: 20 kg. ha -1,50 kg. ha-1, 80 kg. ha-1, 110 kg. ha-1. The evaluated data were processed and recorded into tables and graphs in the results chapter. The highest revenue elements were reached in the variant IV, where was applied 110 kg pure nutrients of nitrogen fertilizer. The revenue elements in individual variants were decreasing with decreasing dose of nitrogen fertilization.
Influence of different tillage technology on the occurrence of weed species in cereals
The bachelor's thesis deals with the action of herbicides in terms of weed control in winter wheat. This is especially the occurrence of annual dicotyledonous weeds, herbaceous and perennial weed species. Of the selected herbicides, the best efficacy was found for the herbicide Mustang Forte in the conventional farming system and lower efficacy for Biathlon 4D when evaluated in a minimized mode of farming. The greatest herbicidal effect was recorded by Biathlon 4D against chamomile weeds.
