Cattle grazed a mixture of cool-season grass frost seeded with a mixture of legumes over a three year study at the Iowa State University Rhodes Research Farm (41° 52’ N, 93° 10’ W). This study was set up to examine the effect of no grazing, rotational and continuous grazing systems along three different landscapes (toeslope, backslope and summit) on weed populations, species diversity and cover of seeded plant populations. Continuously grazing began in late-May through early- to mid-August. Pastures in the rotational system were grazed for a 4 day period in mid-May, early-July, and again in late-October. Cattle were removed from the trial pastures when stubble height was <13 cm and stocking rates were 9.4 AUM/ha in the rotational system and 10.1 AUM/ha in the continuous grazing system. Percent cover method was used to visually estimate cover of each plant species using 0.1 m².
