COMPARATIVE STUDY ON FODDER POTENTIALITIES OF SOME GRASSES OF LOCAL ORIGIN, FOR THE REGION OF THE CENTRAL BALKAN MOUNTAIN

摘要

In the experimental field of RIMSA - Troyan was studied the opportunity for growing of some grasses of local origin for the region of the Central Balkan Mountain.The highest yield for the period of 2011 - 2013 had the tall fescue. Its green mass exceeded the control on the average by 13 42%, and the dry mass by 1.39% The opportunity for growing of French ryegrass and white bentgrass was determined in the condition of highly gleyed pseudopodzolic soils. The perennial ryegrass had the lowest yield. Its green mass л/as by 30.97% less on fhe average for the period of study, аnd the dry mass was by 42.73% less, in comparison with the control. Close in relation to its productivity for the period was Briza maxima L., with average yield of green mass by 29.53% less, and of dry mass by 35.55% less in comparison with the control. The tall fescue had the highest sustainability of development for the period of the studyIn the end of the study (2013), it showed the greatest participation (88 9%) in the total forage yield. Great was the content of whiti bentgrass in the total forage yield - 39 3% Dr 2012 and of French ryegrass - 86 6% for 2012.
