Description
A replacement series experiment was carried out at Chapingo, México aimed to study the seasonal evolution of growth rates of oats (Avena sativa L.) and annual ryegrass (Lolium multiflorum L.) in monocultures and mixtures. Three grazing cycles took place in a period of 181 days. Herbage mass on offer and residual herbage mass were measured, allowing the calculation of herbage accumulation rates. Aggressiveness of oats was higher during the first 105 days growth period, later in the season annual ryegrass was more aggressive than oats. The advantage of the mixture compared to monocultures, depends on a more efficient use of environmental resources due to the combination of the earliness of oats with the higher growth rates of annual ryegrass later in the season.
