Description
The objective of this study was to determine the ensiling properties of ryegrass (Lolium multiflorum L) fertilized with different doses of nitrogen. A pure ryegrass pasture was sown in March 1994 and six N doses (0, 50, 100, 150, 200 and 250 kg N.ha-1) were applied in August 1994. The lots were harvested 60 days after fertilization. The harvested material was chopped and stored for about 60 days in 5 l Polyvinyl chloride (PVC) laboratory silos, and replicated 3 times. Values of DM, IVDMD, TN, NDF, WSC, pH, NH3-N and Sol-N were determined. A completely randomized design was applied, ANOVA for the statistical analyses and Duncan’s test (alpha = 0.05) were used to establish differences between treatments. Nitrogen fertilization in doses of N150 or higher determined critical values (p<0.05) for the fermentation parameters analyzed (DM<13.9%, pH>4.2, Ammonia-N >21.00 % TN and SOL-N>46.8 %TN).
