I N Iowa the acreage planted to oats is second only to that planted to corn and has averaged $y2 million acres annually during, the past 10 years. Since .the yield of oats for this period averaged only 33.4 bushels per acre, it is important that means of raising the acre yield should receive consideration. Outstanding progress is being made by plant breeders in developing new varieties which are superior with respect to disease resistance, yield, stiffness of straw, and resistance to lodging (3). Apparently as a result of the above characteristics, the newer varieties are capable of giving a greater response to fertilizers than are the older varieties (2). During 1944 and 1945 a comprehensive investigation has been in progress to determine the effect of nitrogen, phosphorus, and potassium fertilizers on the yields of oats, largely of the Tama and Boone varieties, on various soils of Iowa. It is the purpose of this paper to summarize the data obtained from these experiments.
