Sažetak
Environmentally sustainable agricultural practices are key for preserving soil physical quality and providing stabile grain yields. The interacted impact of the tillage and organic fertilisation on soil bulk density (BD), penetration resistance (PR), and grain yields is not well understood in a Mediterranean climate. A study was carried out on Anthrosols in a Mediterranean Croatia (Raša valley) during 2017- 2018 period. In split-plot design in three repetitions main plots was conventional tillage (CT), minimum tillage (MT) and reduced tillage (RT). Subplots were treatments with 600 kg ha-1 organic fertiliser (OF), 30 t ha-1 (FMY30) and 15 t ha-1 (FYM15) of farmyard manure. During 2017, MT increased (p < 0.05) BD in the 10–20 cm depth in relation to RT and CT. During 2018 MT increased BD on 0-10 cm and 10-20 cm depths in addition to RT and CT. Reduced tillage treatment had a significantly lower PR comparing to MT and CT in 2017 and significantly lower than MT in 2018. In 2017, CT had significantly lower oat yields compared to RT. During 2018 barley grain yields was significantly the highest under the CT, while under MT was significantly the lowest. Oat grain yields were significantly lower under the PE treatment compared to FMY30 and FMY15 treatments in 2017. During 2017 and 2018 farmyard manure decreased (p < 0.05) BD in addition to OF. Reduced tillage treatments with addition of FMY30 can therefore be considered in Mediterranean environment as proper management strategy for desirable physical conditions and stabile grain yields.
