Response of table beets to fertilizer P and K banded at planting time in 1960 was determined on a Honeoye silt loam soil which had received various levels of complete fertilizer from 1945 to 1951, and different levels of broadcast fertilizer P and K from 1954 to 1959. Soil P from previously applied fertilizer accumulated to a greater extent and had a longer residual effect than soil K as measured by soil tests; however, responses of beets to different levels of soil K were greater than they were to different levels of soil P. At high levels of soil P, there was little response to differences in soil P or banded fertilizer P. At medium levels of soil K, there were considerable increases in percentage of K in the leaves, plant size, and yield with increases in soil K and/or banded fertilizer K. Responses to different levels of soil P and K, and banded fertilizer P and K were cumulative and generally independent of each other. Generally, the soil P and K were relatively as important as the banded fertilizer P and K in producing high yields of beets.
