The purpose of the study energetic input effectiveness of chosen agricultural production activities like sugar beet - basic raw material for the processing industry, potato - a product with multiple uses in farms and in national economy, and broiler chickens, whose meat - due to its various values - is demanded on the market. A positive energetic balance is significant feature of plant products, while in fattening slaughter chicken the index of energetic efficiency is only 0,09. Differentiated structures of the types of energetic outlays for plant production and broiler chicken breeding were observed.
