Impact Of Organo-Mineral Fertilization Upon Phytocoenosis And Feed Quality Of The Grasslands In The Region Of Transylvania

The paper aimes to present the analysis of the qualitative and quantitative changes in the feed obtained as a result of the Festuca rubra - Agrostis capillaris organic and mineral fertilization. The experiment was conducted in 2014, in Baisoara village (Cluj county), at an altitude of 1240 m above sea level. The experiment included four variants in three repetitions, as follows: first variant (V1) - control variant, (unfertilized); second variant (V2) fertilized with 10 t manure/ha; V3 - fertilized with 10 t manure/ha + 50 N + 25 P2O5 + 25 K2O kg/ha active substance/ha; V4 - fertilized with 20 t manure/ha; V5 - fertilized with 10 t manure/ha + 100 N + 50 P2O5 + 50 K2O kg/ha active substance/ha; V6 - fertilized with 100 N + 50 P2O5 + 50 K2O kg active substance/ha. The grass was cut once in 2014, in 2015 and in 2016 and the botanical composition was determined, along with the feed quality. The Festuca rubra L. and Agrostis capillaris L. grassland responded very well to the application of the organic and mineral fertilization.
