The results of investigations in comparative productivity of winter rye in combination with re-sowed cultures and maize for silo are presented. The most productive structure of specimens of forage on anthropogenic transformed degraded bog lands of Polesje is determined. Following links have appeared the most effective structures of specific composition of re-sowed intermediate forage crops on green weight: 1) winter rye (Secale cereale) + maple pea (Pisum arvense) + radish (Raphanus sativus); 2) winter rye (Secale cereale) + radish (Raphanus sativus); 3) maple pea (Pisum arvense) + radish (Raphanus sativus) + maple pea (Pisum arvense); 4) radish (Raphanus sativus) + maple pea (Pisum arvense) + radish (Raphanus sativus). These combinations of cultures on the degraded peat soils during a period May - October can provide animal husbandry with green forage in weight 626-10146 c/ha f.u., or 89,1-124,4 c/ha of f.u., at the content in fodder unit 8-150 g of digestible protein. Total productivity of fodder field in the condensed crops due to intermediate cultures surpasses productivity of field with corn in yield of fodder units on 10-53%, and on provision of fodder unit by digestible protein – in 2,4-3,0 times. The corn forage is less provided by digestible protein, but it is more expensive. It is the base for the winter period in animals maintenance. Productivity of the condensed crops on the degraded peat soils on output of fodder units surpasses efficiency of similar crops on sod-podzol sandy soils of Poles’e on 40-79%
