Present study analyses the suitability of selected grain legumes for integrated production system in Slovenia. Slovenia is a net-importer of grain legumes with approximately 70% of feed proteins imported. Another fact is that about 97.5% of the imported soybean is GM, and that the dependency because of lot imported soybean should be reduced. 18 and 15 different cultivars of soybean, two cultivars of peas and faba-beans were sown at two locations (Jablje and Rakičan) in 2015 to compare morphological traits, yields and content of protein and fat. Results indicate that soybean had higher average yields of grain (DM) and protein content (g kg-1 DM), compared to peas or faba-bean. Higher yields were achieved despite unfavourable growing conditions at both locations in 2015. In Jablje average yields of soybean ranged from 3171 kg ha-1 to 4806 kg ha-1 with average protein content from 335 g kg-1 DM to 405 g kg-1 DM. In Rakičan average yields ranged from 1780 kg ha-1 to 2939 kg ha-1 with average protein content from 296 g kg-1 DM to 375 g kg-1 DM. Average protein yields per hectare with soybean were 1288 and 747 kg ha-1, respectively. In both locations were maturity groups 00 and 000 favourable for production. Maturity groups 0 or 1 proved to be too late maturing and with greater yield variability.
