Description
Pour fodder cropping rotations were compared at different degrees of crop intensification: (RI) a I-year continuous monoculture of Italian ryegrass (Loll111n multij/orum Lam.) +silage maize (Zea mays L.); (R3) a 3-year rotation of Italian ryegrass+silage maize - barley (Hordeum vulgare L.)+silage mai1:e - grain maize; (R6) a 6-year rotation of Italian ryegrass+silage maize for 3 years followed by meadow for 3 years (Trifolium repe11s L. + Festuca ari111di11acea Schreb,): (PM) a monoculture of permanent meadow. The most efficient rotation for dairy cattle feeding, on sandy-loam soils, was the I-year rotation of Italian ryegrass, followed by silage maize, with 22 9S0 milk feed units (MPU)lha, The 3-year rotation without meadow, ranked second, with 18 "ISO MPU/ha. On soils with higher clay content, the 6-year rotation with meadow, in spite of the lower yield (15 9S0 MPU/ha), deserves careful consideration. The permanent meadow, the less intensive rotation, yielded only 16S0 MPU/ha. The experiment indicates that 6.9, S.6, 4.8 and 2.3 adult cattle/ha can be fed with rotations Rl, R3, R6 and PM respectively.
