Název v původním jazyce

Influence of weed infestation on the calorific value and chemical composition of maize (Zea mays L.)

Popis výsledku v původním jazyce

The influence of weed infestation on the calorific value in dry biomass, total energy production and chemical composition of maize was studied in 1998 to 2000. The studied variants were: 1. without weed eradication (control), 2. mechanically weeded fromthe beginning of the vegetation period till the 5-leaf stage of maize, 3. mechanically weeded from the 5-leaf stage of maize till the end of vegetation, 4. mechanically weeded throughout the whole vegetation period, 5. chemically weeded. The mechanical cultivation of the maize stands was done in 14-days intervals. Chemically weeded variant was treated by post-emergence herbicides application. The calorific value in dry matter of maize ranged from 16.57 to 18.13 kJ.g-1. Statistically significant difference (alpha=0.01) among individual parts of plants was recorded. Total energy production of maize particularly depended on biomass yield. Weed infestation caused in variants 1 and 2 significant reduction of maize energy production by 17.23
