Sažetak
The objective of the study was to determine the yield of forage dry matter (DM) of a semi-natural lawn after one year and after ten years of spring and autumn application of farm yrd manure (FYM) in the amount of 30 t ha-1 and to compare the same with the results of standard mineral fertilization. Four fertilizing treatments with fertilizer application were investigated: (i) 30 t ha-1 of FYM every spring (treatment A); 30 t ha-1 of FYM every fall (treatment B); (iii) 0 t ha-1 of FYM + NPK and KAN every spring (treatment C); (iv) 0 t ha-1 of FYM + NPK and KAN every autumn (treatment D). The total average higher DM forage yield (P<0.05) of treatment B (8.28 t ha-1) compared to treatment A (7.63 t ha-1) was determined. Statistically significant differences in DM yield after the first year of the study or after the 10th year of the study were found between A and B fertilizing treatments. Fertilization with mineral fertilizers in the spring (treatment C) and in the autumn (treatment D) resulted in a higher DM yield compared to FYM treatments. It was concluded that, in terms of DM yield, the fertilization of semi-natural lawn with 30 t of FYM ha-1 is more efficient in autumn than in spring. The application of mineral fertilizers was found superior to fertilization with 30 t of FYM ha-1 in spring or autumn.
