Sažetak
Post-harvest cropping is one of the solutions to the growing demands both in food and bio- energy. The sudan grass (Sorghum bicolor subsp. drummondii), trials were set up at three sites in northeastern Croatia during the summers of 2009 and 2010. After the harvests of main crops (winter barley, winter wheat or oilseed rape), three soil tillage treatments were applied: CT) mouldboard ploughing (25-30 cm deep), followed by disk harrowing and seedbed preparation ; HDH) two passes by disk harrow (15-20 cm deep), followed by seedbed preparation, and ; LDH) single pass of disk harrow only. Beside the no- side-dressing control (NO), four sidedressing were applied twice: KAN) 100 kg ha-1 KAN (27 % N) in granular form ; UF) 60 kg ha-1 urea (46 % N), applied as 5 % foliar fertilizer ; PM1) 8 l ha-1 of foliar fertilizer "Profert Mara", which contains macro and micro nutrients, and PM2) double rate of PM1. Significant differences among soil tillage treatments were present. In both years, all side-dressing treatments had higher yield than control. Treatments KAN, UF and PM1 were not different among themselves, whereas PM2 had higher dry matter yield. Results are suggesting better effects of foliar than granular fertilizers for post-harvest sown sudan grass, either in drought (year 2009) or over wet (year 2010) conditions.
