In the southeastern USA annual ryegrass (Lolium multiflorium Lam.) is frequently mixed with commercial fertilizer and broadcast on a lightly disked or undisturbed warm-season perennial grass sod for temporary winter pasture. The implication of mixing annual ryegrass with commercial fertilizer has not been reported. TAM90 annual ryegrass was mixed with either ammonium nitrate (34-0-0), triple superphosphate (0-46-0), or murate of potash (0-0-60). Ryegrass seed was removed 0, 4, 8, 12, 24, and 48 hrs. after mixing with fertilizer and 10 seed planted per pot and placed in the greenhouse. Number of seedlings, rate of seedling emergence, shoot weight, and root weight 4 wk after planting were determined. Plant nutrients nor the amount of time ryegrass seed was in contact with the fertilizer had an effect on the number of seedlings, emergence rate, shoot weight, or root weight.
