Grain sorghum brought maximum yields in Austria

Published Feb 24, 2022

Tridge summary

Grain sorghum crops in Styria, Austria, achieved high yields in 2021, reaching 132 dt/ha, despite concerns from cool May and hot summer weather. The yields exceeded the long-term average, with minimal issues from corn rootworm, borer, or fungal diseases. Sown between late April and mid-May, the crops required weed control and specific herbicides. The results varied by variety, with good crude protein levels. Trials were also conducted in Burgenland and Lower and Upper Austria, with varying yields and leading varieties.

Sorghum millet for grain use surprised last year with good yields. However, the cool May at the start of the season gave rise to serious fears. However, grain millet was able to more than make up for the severely delayed youth development due to the hot summer weather. In the exact test of the province of Styria, grain sorghum reached the maximum value of 2016 of 132 dt/ha with an average dry yield of around 128 dt/ha last year and clearly exceeded the long-term average of 110 dt/ha. Grain sorghum is thus just below the yield level of grain maize, but does not count towards the "grain-maize share" in the crop rotation. Corn rootworm, borer or fungal diseases play no role in the culture. Grain sorghum is sown from the end of April to mid-May at a maize spacing of 70 cm using single-seed technology. With a spacing of 4.6 cm in the row, the seed rate is 311,000 seeds per hectare. Due to the slow development of young plants, weed control is of great importance. In conventional ...
