Effect of cultivation technology on the production characteristics of pea (Pisum sativum)
VACEK, Ondřej
Pea is the most widespread legume in the Czech Republic, with use in both food and feed production. In recent years, the cultivation of crops with larger row spacing has been widely expanded. For this reason, this bachelor thesis focuses on the characteristics of sowing peas, the effect of row spacing and the possibility of reducing the amount of sowing. In the practical part, the thesis focuses on conducting a semi-operational experiment of a pea multiplication crop and evaluating its yield factors and the content of the obtained production. The results obtained show the influence of row spacing and sowing rate on pea yield, number of pods per plant and HTS value, the factor of number of seeds per pod was not affected. Since the experiment was carried out only in one year, it will be necessary to repeat the experiment to refine the results, given the close relationship of the parameters evaluated to the soil and ecological conditions of the particular year. In experiments by other authors, differences in results may also be due to cultivar variability.

Effect of different width of rows on biomass yield and dry matter content at growing sorghum
KUBEŠ, Pavel
The aim of this thesis was to determine the effect of row spacing on sorghum yields and dry matter. The trial was established on 29 May 2015 on land belonging to the Agricultural Cooperative Milevsko, which is situated in the corn-growing area. The trial compared four varieties of sorghum, namely Aristos, Goliath, KWS Freya and KWS Sole. The varieties were sown in different row spacings, namely 75 cm, 60 cm, 45 cm a 30 cm. The samples taken on three dates were analysed for dry matter content. Each variety showed a gradual increase in the dry matter content. During the harvest on 5 October 2015 the varieties KWS Freya and KWS Sole reached an optimal value of the dry matter when planted in all spacings. All varieties produced the highest average yield of green matter when planted in rows spaced 60 cm apart. The variety Aristos produced the highest average yield of green matter. The KWS Sole variety reached the lowest average yield of green matter when planted in rows 76 cm apart. All varieties with 60 cm row spacings, except for KWS Sole, produced the highest average yield of dry matter. The highest average yield of dry matter was reached by Aristos and the lowest by KWS Sole. The results of the one-year trial did not prove a direct connection of the effect of row spacing on dry matter. The effect of row spacing on green and dry matter yield was proved. The optimum row spacing seems to be 60 cm.
