Effects of soil tillage and foliar fertilization on biomass yield of post-harvest seeded sorghum cultivars

The field experiments were carried out near Poljanci, Croatia, during summers 2015 and 2016. Treatments of soil tillage were as follows: MD) one passage with heavy disk harrow and SD) single passage by heavy disk harrow. Sub-treatments of side-dressing were as follows: C) no-sidedressing control ; B) Biological foliar fertilizer (Condi agro), with several aerobic and anaerobic microorganisms, including bacteria, actinomycetes, yeasts and mildews ; and M) Mineral foliar fertilizer (EcoTop Folimax) which contains both macro and micro nutrients. Ten sorghum cultivars were used: KSH3723, KSH3724, Lemnos, Leonie, Merlin, Sammos, Santos, Sole, Tarzan and Zerberus. The present study suggests better effects with foliar fertilizers in comparison with control, regardless of used soil tillage preparation. The results indicate several cultivars (Leonie, Lemnos and KSH3724) which can be used as successful summer catch crops after winter barley.
