Silage maize is a very
important forage crop for ruminants because of its high energy content. In this
study, 50 inbreed lines which were available at the Blacksea Agricultural
Research Station, Samsun, Turkey, were selected as parent genotypes.
The research was designed according to
randomized block design with four replicates. Whole-plant
and stover samples were analyzed for dry matter (DM), acid detergent fiber
(ADF), neutral detergent fiber (NDF), acid detergent lignin (ADL), crude
protein (CP), in vitro digestibility
(IVDMD) and ash. The data were
analyzed with MSTAT statistical program.
There were significant
differences among the inbreed lines for the dry matter yield and forage
quality. Dry matter yield (602.2-2175.3 kg/da), stover yield (295.0-1285.3
kg/da) and, harvest index (23.73-43.83%) values were recorded for inbreed
lines. Acid detergent fiber values were varied
for whole-plant (203.8 to 307.6 g kg-1) and stover (336.6
to 422.5 g kg-1). Neutral detergent fiber values were varied for
whole-plant (430.7 to 576.6 g kg-1) and stover (557.4
to 729.0 g kg-1). Whole-plant IVDMD
(62.39-74.16%) and stover IVDMD (57.40-69.95%) values were ranged. Maize
varieties stovers CP were recorded between 6.29 to 10.54%.
