Other claims from this paper (5)

Observation Fifty sorghum genotypes differed in dry matter yield and concentrations of P, K, Ca, Mg, S, Si, Al, Mn, Cu, and Zn.
Intervention effect Liming did not change low, high, or mean leaf concentrations of P, K, Mg, S, and Cu.
Intervention effect Leaf Al, Mn, and Fe concentrations were higher at 2 than at 6 Mg lime ha‐1.
Intervention effect At 6 Mg ha‐1 lime, leaf Ca and Si concentrations increased.
Recommendation Mineral element concentrations varied enough among genotypes that selection for improved values appears feasible.
