A field experiment, conducted in two locations (Bački Petrovac, Rimski Šančevi) for three years (2006, 2007, 2008), was aimed at assessing the effects of average air temperature (°C) and precipitation sum (mm) during growing season on dry matter yield (kg ha-1) and harvest index of two grain sorghum hybrids (Alba, Gold) and two corn hybrids (NS 300, NS 640). Dry matter yield was gcncraly higher in com than in grain sorghum. In the agroclimatic conditions of southern Bačka, the hybrid Alba was superior to the hybrid Gold and the hybrid NS 640 to NS 300 regarding dry matter yield. The hybrids Gold and NS 300 had a higher harvest index than the hybrids Alba and NS 640, respectively. The increase in average air temperature increased the dry matter yield in the case of grain sorghums and decreased the dry matter yield of corn. Regarding harvest index, decreases were registered with both crops. Increase in rainfall level tended to positively affect the dry matter yield. In the case of grain sorghum, higher harvest index was recorded when dry matter production was reduced. [ABSTRACT FROM AUTHOR]
