Potencial forrageiro de cultivares de girassol produzidos na safrinha para ensilagem.

The objective of this study was to evaluate some important agronomic traits for silage production of 12 hybrids and a variety of sunflower (Helianthus annuus L.) participant of the national assay of sunflower, in the agricultural year of 1996/97. The experiment was conducted from February to June 1997. The experimental procedure followed a randomized block design and the means values were compared by Student-Newman-Keuls test. Significant differences among hybrids for fresh and dry matter productions, leaf, head and stem percentages, stem's circumference close the head, broken plants percentage and height of the plants were observed. No significant differences among hybrids for stem's circumference close the ground, diameter of the head and laying plants percentage were found. The agronomic traits indicated that some hybrids of sunflower present potential to be used for silage production in double-cropping system, or during the drought
