Sažetak
Recent climate changes lead toward possibility of using longer period of higher temperatures after winter crops harvest for establishing post-harvest crop, such is sorghum. It can produce significant biomass, useful both for feed and bioenergy, even in drier summers, with reduced soil tillage preparation. The trial was set up in Poljanci, Croatia, in years 2015 and 2016 as a split-plot design with foliar fertilizers and sorghum cultivars treatments, established by diskharrowing soil after winter wheat harvest in mid-July, and harvested before autumn frosts at the end of November. Foliar fertilizers treatments were C) Control (no fertilization), B) Biological (Condi agro) and M) Mineral (EcoTop Folimax) foliar fertilizers. Cultivars used in trial were KSH3723, KSH3724, Lemnos, Leonie, Merlin, Sammos, Santos, Sole, Tarzan and Zerberus. Foliar fertilizer treatments B and M showed higher dried biomass yield for 7 and 11% in comparison with C, respectively. Difference between treatments were higher at fresh biomass yield. Treatments B and M showed 12 and 22% higher fresh biomass yield than C, respectively. Regarding the tested sorghum cultivars, the highest fresh biomass yield was recorded for Leonie (32933 kg ha-1), followed by Lemnos (27467 kg ha-1) and KSH3724 (26600 kg ha- 1), whereas the lowest yield was recorded for Zerberus (19600 kg ha- 1).
