Starch and protein yield in potatoes for starch production
MIČKA, Michal
The aim of this thesis was to evaluate the starch and protien content in selected potato variarients in relation to nitrogen fertilization. The literature review is a general introduction to the given problem. In the year 2018, a one-year field trial was established where three starch yield varieties Anatori, Hermes a Ornella were observed. Nitrogen fertilizer was applied in two variants. The first variant was fertilized in the spring before planting with a dose of 73 kg N/ha, the second with a dose of 111 kg N/ha.In the experiment, tuber yield, average tuber weight, starch content, starch yield, dry matter content, and crude protein yield were evaluated. In the monitored year of 2018, which had above-average temperatures and on the contrary lowerprecipitation, the best evaluation was the application of higher nitrogen fertilizerswitha dose of 111 kg N/ha. Higher application of nitrogen fertilizers compared to lower dose increased potato tuber yield (t/ha), starch (%) and starch yield (t/ha).
