Application of pig slurry in nutrition and fertilization of potatoes
ŽELEZNÝ, Josef
The aim of the experiment was to evaluate the effect of pig slurry applications in the growing crop of potatoes for industrial processing during the growing season. In 2015, he was at an altitude of 560 m based experiment, where the effect was evaluated by pig slurry at a variety Eurostarch experiment was divided into three variants, each variant had four repetitions, was a variant without application of slurry, 1 times applied manure and 2 times applied manure. For each experiment evaluated the proportion of emerged plants, tuber yield, starch content, average weight 1 tubers and the number of tubers in a bunch. In the reporting year and the effect of the application of manure. From the experimental results it is evident that the manure contributing to higher tuber yield, starch content and increased weight of tubers as the variant with one and two applications of slurry.

Nitrate direction and its influence on agricultural farming
AUBRECHTOVÁ, Vendula
The diploma paper deals with the impact of the Nitrate Direction upon agricultural management in the regions of interest {--} Suchdol nad Lužnicí, Bor u Suchdola nad Lužnicí,and Hrdlořezy u Suchdola nad Lužnicí. Two variants are proposed here of a plant production structure for the application of available amount (14 200 t) of the barnyard manure {--} pig slurry {--} on the agricultural land`s area of 1007,62 ha of which 807,98 ha is the arable land and 199,64 ha is the permanent grass plots. The agricultural land{\crq}s area in the nitrogen vulnerable zone amounts to 354,72 ha of which 327,33 ha is the arable land and 27,39 ha is the permanent grass plots. One of the main limiting criteria of the Nitrate Direction is that the total amount of nitrogen as applied yearly to agricultural land in organic fertilizers, organic mineral fertilizers, and barnyard manures must not exceed a dose of 170 kg N/ha within the entire enterprise on the condition that at least one plot is classified into the nitrogen vulnerable zone. It results from both the proposed variants in this diploma paper that the specified limit of 170 kg N/ha was not exceeded. The management structure selected in both the 1st and the 2nd proposed variant is based on the principles of regular agricultural practices and the adherence to proper environmental conditions in the region of interest.
