Özet:

This study was carried out with the aim of determining the effect of different form frequencies on the herb production in the plants (Panicum virgatum) and some silage food quality characteristics. The study was conducted in 2017 in the Bornova experimental fields of the Department of Farm Plants of the Ziraat Faculty of the University of Ege. In a three-wheeled field test, a 5-year-old flagship genotype called 'Cloud Nine' was used. In the trial, six different forms on plants were tested (30, 60, 90, 120, 150, 180 days). The study measured characteristics such as age grass productivity, plant length, dry substance ratio, silage pH, raw protein ratio, metabolic energy (ME) and relative feed value. The findings showed that the slurry of the form frequency has a significant impact on the age grass productivity and some silage feed quality characteristics, as the form frequency decreases, the ME and the relative feed values (NYD) decreases. It has been determined that the most successful form frequency is the form forms made one every 60 days in the water condition of the Mediterranean climate, taking into account the age grass productivity. In ME and NYD, the highest values are obtained from applications made in a form every 30 days.
