- Abstract
The aim of this study was to determine the effect of organic leaf fertilization on the chemical composition, nutritive value, yield of crude protein (CP) and feed units of natural Agropyron repens grassland in the region of South-Central Bulgaria (305 m altitude). The experiment was carried out with leaf organic fertilizer Naturamin Plus, during the period 2018-2019. The trial was designed by the block method in 4 repetitions and 3 doses of fertilizer were tested: 1500; 2500 and 3500 ml/ha. The obtained results were statistically processed by ANOVA. The applied leaf organic fertilizer Naturamin Plus promoted a positive effect on the productive parameters of natural Agropyron repens grassland but had no significant effect on the chemical composition and nutritive value of the harvested biomass. The results demonstrated that yield of CP, feed units for milk (FUM) and feed units for growth (FUG) increased significantly by fertilization with a dose of 2500 ml/ha - respectively 22.2%, 29.7% and 29.4% more compared to the control.
