Abstract
Three rates of Co, O, 1 and 4 me per pot, and 500 and 1000 lb/acre super were applied to soil in factorial pot experiments. Each rate of fertilizer P was labelled with 0.2 and 4 mu c of P32 per pot. Dry weights, total-P and fertilizer-P contents in tops and roots were depressed at the highest Co level and increased at the higher fertilizer-P treatment. The effects of Co and fertilizer P on total P were independent of dry-weight yields.
