This work includes an agricultural, energy and economic evaluation of fodder grain production (covered oats and barley – single and mixed planting) on light soil. In single planting oats chaffed had the highest yield, while the yield of spring barley and naked oats gave 12% lower yield. Among mixes the highest yield had the mix of covered oats with barley. The energy value per yield (MJ per/hectare) and the energy effectiveness coefficient were best in oats chaffed. The lowest energy effectiveness characterized the spring barley production. Regardless of the sowing method the cost of production of 1 ton of grain was high while the economic effectiveness was low. The production cost of 1 ton of naked oats, Akt, was 16,4 zloty (8%) lower than that of the covered oats – German.
