This diploma thesis deals with the comparison of the influence of three different pre-crops on the spring wheat growing in real conditions of a chosen agricultural business. In 2018, a pilot plant test was established on the property in KÚ Dolní Svince, č.p. 0802/23 with the total area of 13,19 ha. For the establishment of the pilot plant test, an area of 5 ha had been used, which, due to its position, occupied the area of all thre pre-crops (corn for silage, winter barley, winter triticale). During the vegetation period, the occurence of weeds had been monitored and the crop yield elements for all stages of all spring wheat had been evaluated. After the harvest, the real crop yield of the wheat had been evaluated and a final economical evaluation had been made. The average crop yield concerning the first option, (pre-crop corn for silage) reached the yield value of 5,65 t.ha-1 , which was a 0,42 t.ha-1 more than the second option (pre-crop winter barley), in which case the value of harvest was 5,23 t.ha-1. Concerning the third monitored option (pre-crop winter triticale), the harvest value was almost similar to the second option - 5,36 t.ha-1. The most suitable pre-crop for the highest harvest of spring wheat is corn for silage, which has reached the highest profit when compared to the other options. In spite of a less advantageous pre-crop, the third option reached the highest-quality of nitrogen and nitrogen compouns.
