The yield and quality of spring barley in depending on nitrogen fertilization
MACHALOVÁ, Tereza
This diploma thesis deals with nitrogen fertilization of spring barely for malting purposes. The aim of this work was to compare two types of fertilization, areal and variable applications, variety Laudis 550. There were different pre-crops, the first option had corn and the second potatoes as a pre-crop. The result took place using field measurements of yield elements, laboratory measurements and economic evaluation. In the final assessment of the data from this experiment, it was found that variable applications of nitrogen fertilizers are a positive agrotechnical procedure in spring barley. Variable applications result in higher yield and malting quality.

The yield formation of spring barley in depending on nitrogen fertilization
PECA, Tomáš
The theses presents results of experiments with spring barley started in years 2017 and 2018. The experiments were put into practice at Mr Jiří Nepovím's (BSc) place in Opatovice near Světlá nad Sázavou. Laudis 550 was used as the experimental variety of spring barley and the objective of the experiment was to observe the increasing amount of nitrogen and its effect on the resulting quantity and quality. The experimental amounts of nitrogen were set to 60 kg.ha-1, 75 kg.ha-1, 90 kg.ha-1, 105 kg.ha-1 and 120 kg.ha-1. With the increasing amount of nitrogen the crop increased of 0,2 - 0,4 t.ha-1. The share of nitrogen substances in grain increased of 0,2-0,5 %.

The spring barley yield and quality in terms of selected agricultural company
KANTOR, Martin
This Master thesis deals with the yield management evaluation and malting quality of chosen varieties of the spring malting barley in terms of half-working experiment in company "Kantor Václav - Agricultural businessman". There was chosen a stand of experiment and the values of yield management were observed, especially the number of plants, their offshoots and spikes per square unit, the quantity of grains in spikes, the weight of a thousand seeds and the yield. In case of the grain quality elements was rated a content of nitrogen substances, the drop above the sieve 2,8, 2,5, 2,2 mm and under the sieve 2,2 mm, then the content of amyloid, germination and its energy as well as the grain moisture. Among the rated varieties were placed: Malz, Sebastian, Laudis 550, Kangoo, Xanadu, Sunshine, Bojos, KWS Irina and Pionier. The results were filed in the tables and charts. The influence of variety on a different yield element was found out in the final comparison of all parameters. According to the aspect of the yield elements as well as the quality, the best values in this year taking experiment were reached by the Kangoo variety.

The spring barley formation yield growing in terms of selected agricultural company
KANTOR, Martin
Bachelor thesis focus on evaluation of the specific barley cultivars and its harvest profit ratings in the agricultural business conditions " Agricultural businessman Kantor Václav". Values of the harvest profit ratings, amount of plants and its offshoots, quantity of barley spikes per square unit, number of grain in the spike, thousand grain weight of chosen barley cultivars were monitored on the selected location. Between the chosen barley cultivars were Malz, Sebastian, Laudis, Kangoo, Xanadu, Sunshine a Bojos. The results were recorded in tables and charts. In the final comparison of all parameters were found to influence different varieties to yield element. In this one-year pilot experiment achieved the highest yield varieties Sebastian and Xanadu , which would bet he most suitable varieties in this business. Both varieties showed an exellent ability tillering, thereby creating more productive cob. It was confirmed that the spring barley yield consists predominantly number of ears.
