The aim of undertaken study was evaluation of fertilizing value of undersown crops of birdsfoot-trefoil and spring barley straw used for table potato cultivation. Carried out investigations proved, that conditions of vegetation season modified significantly the yielding and chemical content of undersown crops and yield of fresh tubers mass. The fertilizing value of birdsfoot-trefoil with straw, the combination of birdsfoot-trefoil with Italian ryegrass and birdsfoot-trefoil was equal, and even exceeded the fertilizing value of 30 tons dose of farmyard manure applied in potato cultivation
