This paper reviews two-year results of studies on yield and forage quality of soybean cultivars Krajina and Jelica (FAO maturity group 00) double cropped at AIC Becej, in Becej (Serbia) and Institute of Field and Vegetable Crops in Novi Sad (Serbia). With the average crop density of 421,500 plants/ha and irrigation, double cropped soybean produced over 20 t/ha of green forage or over 7 t/ha of dry matter suitable for ensiling. The average stem height was 68.4 cm, the percentage of dry matter at the time of harvest 30.5%. The proportions of stems, leaves and pods in the total biomass were 25.3%, 26.0% and 48.7%, respectively. The average number of pods per stem was 23.4. The feed dehydrated to 90.55% of dry matter had the following average values of crude proteins, crude cellulose, crude fats, crude ashes and N-free extract: 27.1%, 17.06%, 13.29%, 4.66% and 28.42%, respectively. The average value of the feed was very good: the average NEL and NEM values were 6.80 and 7.03 MJ/kg DM.
