Nutrient concentration of selected soybean cultivars

Abstract
Plant samples from 10 cultivars grown on 2 fertility levels were collected. The soybean cultivars were from maturity groups V, VI and VII. The plant samples were analyzed for N, P, K, Ca, Mg, Mn, Zn and Fe. The N, K and Ca concentrations varied more among cultivars. There was no apparent difference in nutrient concentration among the various maturity groups, even though they were sampled at one date.
