Yield and quality of silage of maize hybrids

The objective of this research was to identify the potential of maize hybrids for the production of silage. Hybrids 1671B, 2B433, 20A78, SHS4070, BX1280 and DKB390 were tested in a randomized block design with three replications. The hybrids yields were evaluated (average plant height, height of ear insertion, number of broken and lodged plants/ha, leaf:stem and ear:plant ratio and production of of DM, CP and TDN/ha). There was no difference between hybrids for the variables studied, except for the height of ear insertion. With respect to chemical characteristics, N-NH3/NT organic acids, and pH, there was also no difference between cultivars and hybrid silages are rated as of very good quality
