Adaptive and productive characteristics of perennial meadow grasses in the conditions of the Central Balkan Mountain
Tatyana Bozhanska
Abstract: During the period of 2016-2019 in the experimental field at Research Institute of Mountain Stockbreeding and Agriculture – Troyan was conducted a field experiment. It was traced the adaptability and productivity on perennial forage grasses (Lolium perenne L. – cv. K-11; Lolium multiflorum L. – cv. K-13; Lolium multiflorum L. – cv. K-29t; Festuca arundinaceae Scherb. – cv. K-20; Festuca pratensis Huds. – cv. K-21; Dactylis glomerata L. – cv. K-24 and Bromus inermis Leyss – cv. BV-1 exp.) in the conditions of the Central Balkan Mountain, Bulgaria. The highest average fresh mass productivity in the first (1740.7 kg/da) and second (629.6 kg/da) regrowth, and the highest average dry mass yield in the second regrowth (226.7 kg/da) were found in tall fescue (cv. K-20). Smooth brome (cv. BV-1exp.) achieves maximum yield of dry mass in the first regrowth (487.8 kg/da). Compared to the other types of forage grasses included in the experiment, the Italian ryegrass (cv. K-29t) gave (P <0.05 – P <0.001) the highest grass cover in spring (84.1 cm) and summer (59.8 cm) regrowths.
