Yield of some alternative grazing species in the 1st summer cut at East Croatia

The field trial comprised hay-type lucerne “Mirna”, grazing-type lucerne “Verbena”, perennial forage chicory “Puna II” and several other combinations, which were seeded on the 24th March 2015 near Osijek on a deep fertile soil, in 3 replicates, with basic parcels 5m×1m. The yield was harvested by cutting at height of 4 cm aboveground. The 1st cut was taken on 10th Jun 2015 without any measurements because of excessive weedeness. The 2nd cut was taken on 17th July 2015, when majority of perennial grasses and semi-natural grasslands start to exhibit their summer slump. Average herbage yields of the hay-type lucerne, grazing-type lucerne and chicory were 5.26 t/ha, 4.43 t/ha and 23.9 t/ha, respective. Dry matter (DM) concentrations in herbages were 20% in both lucernes and 7.5% in chicory. Dry matter yields were 1.06 t/ha, 0.89 t/ha and 1.8 t/ha. Considerable weed yields were brought along with targeted species: 2.29 t/ha of DM along with hay-type lucerne, 2.06 with grazing- type lucerne and 1.32 t/ha with chicory. If further investigations confirm the chicory’s superiority this may give a significant lever to farmers’ shift to the grazing dairy operations.
