Yield Comparison Of Sorghum Varieties Depending On Sowing Date And Soil Conditions

Six varieties were tested for silage use in the conditions of more humid location with higher nutrient content (location Obora) and poorer dry soil (location Pisky) in the area of Zabcice, South Moravia. Highest fresh and dry matter yields were measured in the location Pisky, which supports the economic relevance and low-maintenance character of sorghum. Expediency of two sowing dates was evaluated, higher overall yields were observed in sorghum sown in May. Most versatile in the followed year in terms of soil conditions is the variety KWS Titus, in terms of sowing date it is KWS Merlin. Based on fresh and mostly dry matter yields from our study, best properties were found in varieties such as KWS Titus or Pampa Centurion (sown in May) and KWS Merlin (sown in June) on fertile soil conditions. For areas with less fertile soil, best properties were found in KWS Titus, KWS Merlin and Triunfo BMR. Lowest yields were observed in Sweet Susana variety and therefore it was deemed not sufficiently yielding.y
