Evaluation of the expenditure and energy in production technology of sweet maize corn cobs for fresh-market was the objective of this work. Four growing variants were analyzed: direct-seeded plants without plastic cover (variant I), directseeded plants with plastic cover (variant II), plant growing with plastic cover (variant III), plant growing without plastic cover (variant IV). The sweet maize corn varieties: Candle, Sweet Trophy and Golda were analyzed. The expenditure of labour and energy recast in area and cobs yield for the whole varieties was the highest in variant IV and the smallest in variant The differences between varieties were caused by the changes in cobs yield and especially by the number of cobs.
