Weed infestation influence on chemical composition of silage maize (Zea mays L.)

Popis výsledku v původním jazyce

The influence of various ways of regulation in weed infestation of silage maize stands was studied in 1998 - 2000. Four variants of stands were compared: 1. without weed eradication (check), 2. mechanically weeded from the phase of 5th maize leaf till the end of vegetation, 3. mechanically weeded from the beginning of vegetation till the phase of 5th maize leaf and later on without protection, 4. chemical weeding. The percentage of ears, husks, stalks and leaves was evaluated from total weight of maizeplant in dependence weed infestation. The qualitative parameters of silage maize biomass were evaluated. There was proved, that weed infestation negatively influences the total plant weight of maize, but there is no influence on percentage share of indi vidual plant parts. Qualitative parameters of harvested biomass are worsening by presence of weeds. Energy content (NEL, NEG) is decreased and content of ash and crude fibre is increased. Variant with fungicide treatment showed the highest
