Abstract

During the falls of 1965 and 1966 ‘Amcl’ clover (Trifolium vesiculosum) was allowed to volunteer, and starting the following spring in mid-March new plots were clipped each week to establish the rate of dry matter and cell wall development accumulation. The clipping was continued until early June at which stage the clover had matured. Data obtained indicated that Amclo was capable of producing more than 100 kg/ha of dry forage each day at the peak of productivity. In dry years, however, a much lower level of productivity can be expected. In the young vegetative forage, cell walls comprised less than 40% of the total yield. During flowering, cell walls increased to 40 to 47% of the total yield. At maturity cell walls increased to more than 50% of the total. Both yield and cell walls varied significantly between years.
