Abstract

Grain, straw and cob percentage in ears of corn was studied in an experiment where 20 cultivars for silage production were under evaluation, in Ribeirão Preto, SP, Brazil. A randomized block design with 2 replications was used. The corn was sampled when plants were completely mature and dried. The results showed that grain percentage varied from 74.57 to 65.32% and differences (p < 0,05) were detected between cultivars. Straw plus cob percentages varied from 25.42 to 34.67% and there were diferences (p < 0.05) between cultivars for both straw and cob percentages. There were diferences (p < 0.05) between cultivars for crude protein percentages of the ground ears, that varied from 7.87 to 11.09% according to the cultivars. Grain crude protein percentages varied from 9,14 to 13,51 % and diferences (p < 0.05) were found between cultivars.
