Abstract

The aim of the work was to confirm the hypothesis that broad bean (Vicia faba) is better harvested for silage directly than by wilting, and that the semi-early variety Mistral has better parameters than the older semilate variety Merkur. The broad bean was grown in the Malá Haná area at an altitude of 441 m. There was significantly less precipitation in the area from April to the end of July and the temperature was comparable to the normal from 1991 to 2020. The broad beans were harvested for silage into 4l bottles 15 weeks after sowing, and the bottles were opened for analysis after 19 weeks. The forage was harvested at a dry matter content of 42.9%, compared to a dry matter content of 64.1% after wilting. Silage after direct harvest had better silage quality indicators and lower dry matter losses than after wilting. The Mistrál variety had a better evaluation of the fermentation process. The hypotheses were confirmed.
