The Waterboard Vallei en Veluwe, and LaMi have financed comparative research of five sorghum crops and maize on a sandy soil in Woudenberg. The average yield of the five sorghum crops studied was low and equal to those of maize (11.5 tonnes DM/ha). The most important causes are the dry and warm climate, and the poorer soil structure. It should be noted that the maize variety was sown three to four weeks later than normal. With regard to the feed value most sorghum crops have a relatively low starch content, low DCOM (Digestibility Coefficient of the Organic Matter), a relatively high crude protein content and a relatively high ADL (Acid Detergent Fiber) content, compared to maize. It was concluded that the sorghum crop STH 16149 was not suitable as a high-quality fodder crop. The soil moisture content did not differ between varieties. In the soil layer 0-90 cm, maize had the highest residual-N: 62 kg residual-N/ha, whereas the average value of the five sorghum varieties in this layer was 48 kg residual-N/ha. No significant differences between varieties were observed in residual-N (kg/ha) per soil layer 0-30 cm, 30-60 cm and 60-90 cm.
