Abstract
Abstract Effects were studied of fertilizer applications for nodulating and non‐nodulating soybeans and of varieties on the amounts of N, P, and K accumulated in aboveground plant parts of soybeans at successive stages of plant development. Total accumulation of N, P, and K in the plants followed patterns similar to that of drymatter accumulation. Rates of accumulation were slow early in the season, but became rapid, and the nutrients accumulated at constant daily rates between stages 5 and 9. Approximately 79% of the total accumulation of these nutrients occurred during the 46‐day period between stages 5 and 9. Approximately half of the N, P, and K in the mature seeds were translocated from other plant parts, and the remaining half taken up from the soil and nodules during seed development. Fertilizer applications increased the amounts of N, P, and K accumulated by the plants. Nutrient accumulation was similar in 8 varieties.
