Description
The objective of this study was to study the establishment dynamics and persistence of a legume mixture oversown into natural grasslands under five different grazing management systems. Topographic position had the most significant effect on establishment and persistence. The lowlands were the best sites for legume establishment and persistence. Two years of previous management changed the ground cover components affecting the germination pattern of introduced seeds. The more frequent grazing treatments increased the total number of established legumes and their persistence throughout five years of grazing in the lowlands. Legume persistence on the slopes was generally shorter and was optimized under intermediate defoliation frequencies (rest periods of 40 and 60 days). The performance of each legume was optimized at a different grazing frequency. Site selection and grazing management were the main factors conditioning their establishment, contribution and persistence.
