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. At the same time, it can uptake mineral nutrients left after previous crop, and prevent their leaching into environment, showing its "catch-crop" function. 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. Cultivars showed N uptake range between 41 and 110 kg N ha- 1, P uptake range between 18 and 38 kg P2O5 ha-1, and K uptake range between 71 and 133 kg K2O ha-1. In comparison with C treatment, B and M treatments facilitated significantly higher N and K uptake in most cultivars.
