Abstract

The objective of this work was to evaluate the total dry matter production (TDMP) of stem (DMs), leaves (DMl), ear (DMe), crude protein content (CPC), acid detergent fiber (ADF), plant height (PH) and stem/leaves relation (S/L) of the hybrids (Zea mays L.) AG 122, AG 519, C 525, C 805, D 170, D 771, G 600, G 1328, P 3041, P 3069, XL 520, XL 530, OC 705, FO 01. The results indicated that the hybrid FO 01 showed the highest dry matter production, the highest plant and stem production, but the smallest ear and leaves percentage, decreasing the quality of the original material. The higher productivity of hybrids was associated with a higher plant height and stem production on total dry matter. The hybrid G 1328 showed a good dry matter production with equilibrium in the relation leaves/stem/corn cob.
