YIELD AND CHEMICAL COMPOSITION OF SILAGE PRODUCED BY DIFFERENT CORN HYBRIDS
CORN HYBRIDS YIELD AND CHEMICAL COMPOSITION
Abstract
The objective of this study was to evaluate the agronomic performance of corn hybrids cultivated for silage production and the chemical composition of the ensiled material. The experiment was conducted from September 2022 to August 2023, under field and laboratory conditions, at the Federal Institute of Education, Science and Technology of Rondônia, Colorado do Oeste Campus, in the municipality of Colorado do Oeste, RO. The experimental design was completely randomized, consisting of seven corn hybrids (BM3063PRO3, BM709PRO3, BM990VIP3, BM3088 VTPRO4, HLX2045PRO2, KWS9606VIP3 and Defender VIP3) and five replications. In the R5 phenological stage, the production components were determined and in the second experimental stage, the remaining material in the useful area of each experimental unit was chopped in a manual silage machine for silage preparation. After the 70-day fermentation period, the silos were opened and samples were taken to determine the nutritional value of the silage. The results allowed us to conclude that there is variation in the agronomic performance of commercial corn hybrids for the southern region of Rondônia; and that the hybrid BM990 VIP3 stood out in terms of green mass yield, N and P content in the shoots, as well as in the contents of NDF, ADF, starch, lignin, acetic acid in the silage, allowing to infer a better alternative for production and silage of high nutritional value and good digestibility, due to the lower amount of fiber and higher amount of digestible and metabolizable energy.
