Determination of correlation dependences of seed crop yield of slough grass (Beckmannia eruciformis) on soil features was realized in the conditions of the Republic of Belarus on sod-podzolic gleyic soils. Beckmania eruciformis is a perennial, hygrophilous, and rhizomatous grass. In course of the research there were made linear and not linear correlation dependences of seed productivity of Beckmania eruciformis from such factors as content of humus in soil, volume humidity and doses of the mineral fertilizers. As a result of realized research it was revealed that seed productivity of Beckmania eruciformis had a linear dependence from potential and effective soil fertility. Use equations of the dependences made it possible to calculate the biological seed productivity of Beckmania eruciformis, based on security of soil humus and volume humidity. The value of seed productivity in this case made it possible to value the influence of potential fertility. For the purpose of estimation of effective soil fertility the equations of correlation dependences taking into account doses of the used mineral fertilizers also were resulted.
